Squash attributes into the pointer's integer, making them an uintptr_t
pair containing 2 bits at the bottom and then the pointer. These bits
are currently unused thanks to alignment requirements.
Configure Dynarmic to mask out these bits on pointer reads.
While we are at it, remove some unused attributes carried over from
Citra.
Read/Write and other hot functions use a two step unpacking process that
is less readable to stop MSVC from emitting an extra AND instruction in
the hot path:
mov rdi,rcx
shr rdx,0Ch
mov r8,qword ptr [rax+8]
mov rax,qword ptr [r8+rdx*8]
mov rdx,rax
-and al,3
and rdx,0FFFFFFFFFFFFFFFCh
je Core::Memory::Memory::Impl::Read<unsigned char>
mov rax,qword ptr [vaddr]
movzx eax,byte ptr [rdx+rax]
Some games such as NEKOPARA Vol. 3 send invalid device handles when calling InitializeVibrationDevice. Introduce a check to validate the device handle before use.
Simplifies and removes some casts. In all cases, these were generally
widening from a 32-bit unsigned type to a 64-bit unsigned type, so no
information would be lost from the conversion.
Actually, two enum classes, since for some reason there are two separate
yet identical `PollFD` types used in the codebase. I get that one is
ABI-compatible with the Switch while the other is an abstract type used
for the host, but why not use `WSAPOLLFD` directly for the latter?
Anyway, why make this change? Because on Apple platforms, `POLL_IN`,
`POLL_OUT`, etc. (with an underscore) are defined as macros in
<sys/signal.h>. (This is inherited from FreeBSD.) So defining
a variable with the same name causes a compile error.
I could just rename the variables, but while I was at it I thought I
might as well switch to an enum for stronger typing.
Also, change the type used for values copied directly to/from the
`events` and `revents` fields of the host *native*
`pollfd`/`WSASPOLLFD`, from `u32` to `short`, as `short` is the correct
canonical type on both Unix and Windows.
`PhysicalCore`'s move assignment operator was declared as `= default`,
but was implicitly deleted because `PhysicalCore` has fields
of reference type. Switch to explicitly deleting it to avoid a Clang
warning.
The move *constructor* is still defaulted, and is required to exist due
to the use of `std::vector<PhysicalCore>`.
- Add a type check so that calling Push with an invalid type produces a
compile error rather than a linker error.
- vi.cpp was calling Push with a variable of type `std::size_t`.
There's no explicit overload for `size_t`, but there is one for `u64`,
which on most platforms is the same type as `size_t`. On macOS,
however, it isn't: both types are 64 bits, but `size_t` is `unsigned
long` and `u64` is `unsigned long long`. Regardless, it makes more
sense to explicitly use `u64` here instead of `size_t`.
