CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet. Will need to evaluate them (eg. is there a reasonable max number of params for Calls?) * ConcurrentStack instead of ConcurrentQueue for Rejit * Optimize some parts of LSRA - BitMap now operates on 64-bit int rather than 32-bit - BitMap is now pooled in a ThreadStatic pool (within lrsa) - BitMap now is now its own iterator. Marginally speeds up iterating through the bits. - A few cases where enumerators were generated have been converted to forms that generate less garbage. - New data structure for sorting _usePositions in LiveIntervals. Much faster split, NextUseAfter, initial insertion. Random insertion is slightly slower. - That last one is WIP since you need to insert the values backwards. It would be ideal if it just flipped it for you, uncomplicating things on the caller side. * Use a static pool of thread static pools. (yes.) Prevents each execution thread creating its own lowCq pool and making me cry. * Move constant value to top, change naming convention. * Fix iteration of memory operands. * Increase max thread count. * Address Feedback

Reduce JIT GC allocations (#2515) * Turn `MemoryOperand` into a struct * Remove `IntrinsicOperation` * Remove `PhiNode` * Remove `Node` * Turn `Operand` into a struct * Turn `Operation` into a struct * Clean up pool management methods * Add `Arena` allocator * Move `OperationHelper` to `Operation.Factory` * Move `OperandHelper` to `Operand.Factory` * Optimize `Operation` a bit * Fix `Arena` initialization * Rename `NativeList<T>` to `ArenaList<T>` * Reduce `Operand` size from 88 to 56 bytes * Reduce `Operation` size from 56 to 40 bytes * Add optimistic interning of Register & Constant operands * Optimize `RegisterUsage` pass a bit * Optimize `RemoveUnusedNodes` pass a bit Iterating in reverse-order allows killing dependency chains in a single pass. * Fix PPTC symbols * Optimize `BasicBlock` a bit Reduce allocations from `_successor` & `DominanceFrontiers` * Fix `Operation` resize * Make `Arena` expandable Change the arena allocator to be expandable by allocating in pages, with some of them being pooled. Currently 32 pages are pooled. An LRU removal mechanism should probably be added to it. Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

Reduce JIT GC allocations (#2515) * Turn `MemoryOperand` into a struct * Remove `IntrinsicOperation` * Remove `PhiNode` * Remove `Node` * Turn `Operand` into a struct * Turn `Operation` into a struct * Clean up pool management methods * Add `Arena` allocator * Move `OperationHelper` to `Operation.Factory` * Move `OperandHelper` to `Operand.Factory` * Optimize `Operation` a bit * Fix `Arena` initialization * Rename `NativeList<T>` to `ArenaList<T>` * Reduce `Operand` size from 88 to 56 bytes * Reduce `Operation` size from 56 to 40 bytes * Add optimistic interning of Register & Constant operands * Optimize `RegisterUsage` pass a bit * Optimize `RemoveUnusedNodes` pass a bit Iterating in reverse-order allows killing dependency chains in a single pass. * Fix PPTC symbols * Optimize `BasicBlock` a bit Reduce allocations from `_successor` & `DominanceFrontiers` * Fix `Operation` resize * Make `Arena` expandable Change the arena allocator to be expandable by allocating in pages, with some of them being pooled. Currently 32 pages are pooled. An LRU removal mechanism should probably be added to it. Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet.

Reduce JIT GC allocations (#2515) * Turn `MemoryOperand` into a struct * Remove `IntrinsicOperation` * Remove `PhiNode` * Remove `Node` * Turn `Operand` into a struct * Turn `Operation` into a struct * Clean up pool management methods * Add `Arena` allocator * Move `OperationHelper` to `Operation.Factory` * Move `OperandHelper` to `Operand.Factory` * Optimize `Operation` a bit * Fix `Arena` initialization * Rename `NativeList<T>` to `ArenaList<T>` * Reduce `Operand` size from 88 to 56 bytes * Reduce `Operation` size from 56 to 40 bytes * Add optimistic interning of Register & Constant operands * Optimize `RegisterUsage` pass a bit * Optimize `RemoveUnusedNodes` pass a bit Iterating in reverse-order allows killing dependency chains in a single pass. * Fix PPTC symbols * Optimize `BasicBlock` a bit Reduce allocations from `_successor` & `DominanceFrontiers` * Fix `Operation` resize * Make `Arena` expandable Change the arena allocator to be expandable by allocating in pages, with some of them being pooled. Currently 32 pages are pooled. An LRU removal mechanism should probably be added to it. Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet. Will need to evaluate them (eg. is there a reasonable max number of params for Calls?) * ConcurrentStack instead of ConcurrentQueue for Rejit * Optimize some parts of LSRA - BitMap now operates on 64-bit int rather than 32-bit - BitMap is now pooled in a ThreadStatic pool (within lrsa) - BitMap now is now its own iterator. Marginally speeds up iterating through the bits. - A few cases where enumerators were generated have been converted to forms that generate less garbage. - New data structure for sorting _usePositions in LiveIntervals. Much faster split, NextUseAfter, initial insertion. Random insertion is slightly slower. - That last one is WIP since you need to insert the values backwards. It would be ideal if it just flipped it for you, uncomplicating things on the caller side. * Use a static pool of thread static pools. (yes.) Prevents each execution thread creating its own lowCq pool and making me cry. * Move constant value to top, change naming convention. * Fix iteration of memory operands. * Increase max thread count. * Address Feedback

CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet. Will need to evaluate them (eg. is there a reasonable max number of params for Calls?) * ConcurrentStack instead of ConcurrentQueue for Rejit * Optimize some parts of LSRA - BitMap now operates on 64-bit int rather than 32-bit - BitMap is now pooled in a ThreadStatic pool (within lrsa) - BitMap now is now its own iterator. Marginally speeds up iterating through the bits. - A few cases where enumerators were generated have been converted to forms that generate less garbage. - New data structure for sorting _usePositions in LiveIntervals. Much faster split, NextUseAfter, initial insertion. Random insertion is slightly slower. - That last one is WIP since you need to insert the values backwards. It would be ideal if it just flipped it for you, uncomplicating things on the caller side. * Use a static pool of thread static pools. (yes.) Prevents each execution thread creating its own lowCq pool and making me cry. * Move constant value to top, change naming convention. * Fix iteration of memory operands. * Increase max thread count. * Address Feedback

CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet. Will need to evaluate them (eg. is there a reasonable max number of params for Calls?) * ConcurrentStack instead of ConcurrentQueue for Rejit * Optimize some parts of LSRA - BitMap now operates on 64-bit int rather than 32-bit - BitMap is now pooled in a ThreadStatic pool (within lrsa) - BitMap now is now its own iterator. Marginally speeds up iterating through the bits. - A few cases where enumerators were generated have been converted to forms that generate less garbage. - New data structure for sorting _usePositions in LiveIntervals. Much faster split, NextUseAfter, initial insertion. Random insertion is slightly slower. - That last one is WIP since you need to insert the values backwards. It would be ideal if it just flipped it for you, uncomplicating things on the caller side. * Use a static pool of thread static pools. (yes.) Prevents each execution thread creating its own lowCq pool and making me cry. * Move constant value to top, change naming convention. * Fix iteration of memory operands. * Increase max thread count. * Address Feedback

Reduce JIT GC allocations (#2515) * Turn `MemoryOperand` into a struct * Remove `IntrinsicOperation` * Remove `PhiNode` * Remove `Node` * Turn `Operand` into a struct * Turn `Operation` into a struct * Clean up pool management methods * Add `Arena` allocator * Move `OperationHelper` to `Operation.Factory` * Move `OperandHelper` to `Operand.Factory` * Optimize `Operation` a bit * Fix `Arena` initialization * Rename `NativeList<T>` to `ArenaList<T>` * Reduce `Operand` size from 88 to 56 bytes * Reduce `Operation` size from 56 to 40 bytes * Add optimistic interning of Register & Constant operands * Optimize `RegisterUsage` pass a bit * Optimize `RemoveUnusedNodes` pass a bit Iterating in reverse-order allows killing dependency chains in a single pass. * Fix PPTC symbols * Optimize `BasicBlock` a bit Reduce allocations from `_successor` & `DominanceFrontiers` * Fix `Operation` resize * Make `Arena` expandable Change the arena allocator to be expandable by allocating in pages, with some of them being pooled. Currently 32 pages are pooled. An LRU removal mechanism should probably be added to it. Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet. Will need to evaluate them (eg. is there a reasonable max number of params for Calls?) * ConcurrentStack instead of ConcurrentQueue for Rejit * Optimize some parts of LSRA - BitMap now operates on 64-bit int rather than 32-bit - BitMap is now pooled in a ThreadStatic pool (within lrsa) - BitMap now is now its own iterator. Marginally speeds up iterating through the bits. - A few cases where enumerators were generated have been converted to forms that generate less garbage. - New data structure for sorting _usePositions in LiveIntervals. Much faster split, NextUseAfter, initial insertion. Random insertion is slightly slower. - That last one is WIP since you need to insert the values backwards. It would be ideal if it just flipped it for you, uncomplicating things on the caller side. * Use a static pool of thread static pools. (yes.) Prevents each execution thread creating its own lowCq pool and making me cry. * Move constant value to top, change naming convention. * Fix iteration of memory operands. * Increase max thread count. * Address Feedback

Reduce JIT GC allocations (#2515) * Turn `MemoryOperand` into a struct * Remove `IntrinsicOperation` * Remove `PhiNode` * Remove `Node` * Turn `Operand` into a struct * Turn `Operation` into a struct * Clean up pool management methods * Add `Arena` allocator * Move `OperationHelper` to `Operation.Factory` * Move `OperandHelper` to `Operand.Factory` * Optimize `Operation` a bit * Fix `Arena` initialization * Rename `NativeList<T>` to `ArenaList<T>` * Reduce `Operand` size from 88 to 56 bytes * Reduce `Operation` size from 56 to 40 bytes * Add optimistic interning of Register & Constant operands * Optimize `RegisterUsage` pass a bit * Optimize `RemoveUnusedNodes` pass a bit Iterating in reverse-order allows killing dependency chains in a single pass. * Fix PPTC symbols * Optimize `BasicBlock` a bit Reduce allocations from `_successor` & `DominanceFrontiers` * Fix `Operation` resize * Make `Arena` expandable Change the arena allocator to be expandable by allocating in pages, with some of them being pooled. Currently 32 pages are pooled. An LRU removal mechanism should probably be added to it. Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

Reduce JIT GC allocations (#2515) * Turn `MemoryOperand` into a struct * Remove `IntrinsicOperation` * Remove `PhiNode` * Remove `Node` * Turn `Operand` into a struct * Turn `Operation` into a struct * Clean up pool management methods * Add `Arena` allocator * Move `OperationHelper` to `Operation.Factory` * Move `OperandHelper` to `Operand.Factory` * Optimize `Operation` a bit * Fix `Arena` initialization * Rename `NativeList<T>` to `ArenaList<T>` * Reduce `Operand` size from 88 to 56 bytes * Reduce `Operation` size from 56 to 40 bytes * Add optimistic interning of Register & Constant operands * Optimize `RegisterUsage` pass a bit * Optimize `RemoveUnusedNodes` pass a bit Iterating in reverse-order allows killing dependency chains in a single pass. * Fix PPTC symbols * Optimize `BasicBlock` a bit Reduce allocations from `_successor` & `DominanceFrontiers` * Fix `Operation` resize * Make `Arena` expandable Change the arena allocator to be expandable by allocating in pages, with some of them being pooled. Currently 32 pages are pooled. An LRU removal mechanism should probably be added to it. Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet. Will need to evaluate them (eg. is there a reasonable max number of params for Calls?) * ConcurrentStack instead of ConcurrentQueue for Rejit * Optimize some parts of LSRA - BitMap now operates on 64-bit int rather than 32-bit - BitMap is now pooled in a ThreadStatic pool (within lrsa) - BitMap now is now its own iterator. Marginally speeds up iterating through the bits. - A few cases where enumerators were generated have been converted to forms that generate less garbage. - New data structure for sorting _usePositions in LiveIntervals. Much faster split, NextUseAfter, initial insertion. Random insertion is slightly slower. - That last one is WIP since you need to insert the values backwards. It would be ideal if it just flipped it for you, uncomplicating things on the caller side. * Use a static pool of thread static pools. (yes.) Prevents each execution thread creating its own lowCq pool and making me cry. * Move constant value to top, change naming convention. * Fix iteration of memory operands. * Increase max thread count. * Address Feedback

Apparently MHR can allocate bitmaps large enough to exceed the 16MB limit for the type. * Move `Arena` & `ArenaList` to `Common` * Remove `ThreadStaticPool` & co * Add `PhiOperation` * Reduce `Operand` size from 56 from 48 bytes * Add linear-probing to `Operand` intern table * Optimize `HybridAllocator` a bit * Add `Allocators` class * Tune `ArenaAllocator` sizes * Add page removal mechanism to `ArenaAllocator` Remove pages which have not been used for more than 5s after each reset. I am on fence if this would be better using a Gen2 callback object like the one in System.Buffers.ArrayPool<T>, to trim the pool. Because right now if a large translation happens, the pages will be freed only after a reset. This reset may not happen for a while because no new translation is hit, but the arena base sizes are rather small. * Fix `OOM` when allocating larger than page size in `ArenaAllocator` Tweak resizing mechanism for Operand.Uses and Assignemnts. * Optimize `Optimizer` a bit * Optimize `Operand.Add<T>/Remove<T>` a bit * Clean up `PreAllocator` * Fix phi insertion order Reduce codegen diffs. * Fix code alignment * Use new heuristics for degree of parallelism * Suppress warnings * Address gdkchan's feedback Renamed `GetValue()` to `GetValueUnsafe()` to make it more clear that `Operand.Value` should usually not be modified directly. * Add fast path to `ArenaAllocator` * Assembly for `ArenaAllocator.Allocate(ulong)`: .L0: mov rax, [rcx+0x18] lea r8, [rax+rdx] cmp r8, [rcx+0x10] ja short .L2 .L1: mov rdx, [rcx+8] add rax, [rdx+8] mov [rcx+0x18], r8 ret .L2: jmp ArenaAllocator.AllocateSlow(UInt64) A few variable/field had to be changed to ulong so that RyuJIT avoids emitting zero-extends. * Implement a new heuristic to free pooled pages. If an arena is used often, it is more likely that its pages will be needed, so the pages are kept for longer (e.g: during PPTC rebuild or burst sof compilations). If is not used often, then it is more likely that its pages will not be needed (e.g: after PPTC rebuild or bursts of compilations). * Address riperiperi's feedback * Use `EqualityComparer<T>` in `IntrusiveList<T>` Avoids a potential GC hole in `Equals(T, T)`.

CodeGen Optimisations (LSRA and Translator) (#978) * Start of JIT garbage collection improvements - thread static pool for Operand, MemoryOperand, Operation - Operands and Operations are always to be constructed via their static helper classes, so they can be pooled. - removing LinkedList from Node for sources/destinations (replaced with List<>s for now, but probably could do arrays since size is bounded) - removing params constructors from Node - LinkedList<> to List<> with Clear() for Operand assignments/uses - ThreadStaticPool is very simple and basically just exists for the purpose of our specific translation allocation problem. Right now it will stay at the worst case allocation count for that thread (so far) - the pool can never shrink. - Still some cases of Operand[] that haven't been removed yet. Will need to evaluate them (eg. is there a reasonable max number of params for Calls?) * ConcurrentStack instead of ConcurrentQueue for Rejit * Optimize some parts of LSRA - BitMap now operates on 64-bit int rather than 32-bit - BitMap is now pooled in a ThreadStatic pool (within lrsa) - BitMap now is now its own iterator. Marginally speeds up iterating through the bits. - A few cases where enumerators were generated have been converted to forms that generate less garbage. - New data structure for sorting _usePositions in LiveIntervals. Much faster split, NextUseAfter, initial insertion. Random insertion is slightly slower. - That last one is WIP since you need to insert the values backwards. It would be ideal if it just flipped it for you, uncomplicating things on the caller side. * Use a static pool of thread static pools. (yes.) Prevents each execution thread creating its own lowCq pool and making me cry. * Move constant value to top, change naming convention. * Fix iteration of memory operands. * Increase max thread count. * Address Feedback
