Lioncash 763778e6c0 gl_rasterizer: Make const on references consistent 
Applies const to auto& instances that would actually resolve to a const
reference for readability and explicitness.

Lioncash df97021f55 gl_rasterizer: Make use of std::string_view in IsVendorAmd() 
Same behavior, no heap allocation.

strings returned from glGetString() are guaranteed to be static strings,
so this is safe to do. They're also guaranteed to be null-terminated.

Lioncash 59a614a70f gl_rasterizer_cache: Remove unnecessary reference parameter in LoadCustomTexture() 
This is only ever used in a self-referential manner, so we can make use
of the texture info member directly.

Lioncash e342f36e02 gl_rasterizer_cache: Flatten LoadCustomTexture() 
Makes the control flow much nicer to follow, as we don't store to a
local before returning anymore.

gl_shader_disk: Make use of std::nullopt where applicable (#5293) 
Some implementations can use the std::nullopt_t constructor of
std::optional to avoid needing to completely zero out the internal
buffer of the optional and instead only set the validity byte within it.

e.g. Consider the following function:

std::optional<std::vector<ShaderDiskCacheRaw>> fn() {
    return {};
}

With libc++ this will result in the following code generation on x86-64:

Fn():
  mov     rax, rdi
  vxorps  xmm0, xmm0, xmm0
  vmovups ymmword ptr [rdi], ymm0
  vzeroupper
  ret

With libstdc++, we also get the similar equivalent:

Fn():
  vpxor   xmm0, xmm0, xmm0
  mov     rax, rdi
  vmovdqu XMMWORD PTR [rdi], xmm0
  vmovdqu XMMWORD PTR [rdi+16], xmm0
  ret

If we change this function to return std::nullopt instead, then this
simplifies both the code gen from libc++ and libstdc++ down to:

Fn():
  mov     BYTE PTR [rdi+24], 0
  mov     rax, rdi
  ret

Given how little of a change is necessary to result in better code
generation, this is essentially a "free" very minor optimization.

Lioncash f20120e5a7 gl_shader_gen: Mark hash implementations as noexcept

Lioncash 41b7df4a32 command_processor: Resolve undefined behavior type punning 
We can use std::memcpy to achieve the same behavior without undefined
behavior. Once Citra moves to C++20 we can convert this over to
std::bit_cast.

Lioncash 623cc926ed post_processing_opengl: Make use of std::string_view with GetPostProcessingShaderCode() 
Same behavior, but doesn't result in an allocating copy of the passed in
string. Particularly given the string is only compared against other
existing strings.

Lioncash c72d9b806b gl_shader_manager: std::move std::string where applicable 
Prevents unnecessary copies from occurring. In the case of ShaderCache,
we can just remove the parameter, given it's unused.

Lioncash 12d4c835db geometry_pipeline: std::move vertex handler in SetVertexHandler() 
std::function is allowed to internally allocate, so this prevents
potential reallocations from occurring, should that case ever happen.
 2020-04-18 21:26:47 -04:00
Lioncash 12279b22cc gl_resource_manager: Make use of noexcept on move assignment and move constructors 
Several standard constructors generally check if objects can be moved in
a non-throwing manner (usually via std::move_if_noexcept) to preserve
its exception guarantees. This means that if these were used with
certain containers any reallocations internally would cause resource
churn, as copies would be necessary instead of moves.

This way, if they're every used in that manner, the right behavior is
always performed.

Lioncash 2cefd16850 primitive_assembly: Mark constructor explicit

Lioncash 59bb84b86c primitive_assembly: Take triangle_handler by reference 
Avoids copying the std::function when we don't need to. Particularly
given the std::function isn't actually stored anywhere, so there's no
need to move it.
