it's a little strange how the resolver takes an arbitrary intermediate
in it's constructor. Really this should be an 'options' object that
holds the various resolve/remapping options which are read from this
intermediate.
At least for now rename it so it's more clear it's used differently from
other intermediates that are accessed in the resolver (such as the per
stage ones).
* add ability to upgrade uniform block to push constants assuming it fits within the size limit imposed by the caller
* allow selecting the packing for the auto push constants
* check the size using the potential layout packing of the push constants
instead of allowing for multiple declarations of the variable in the
resulting SPIR-V, instead use a retargeted mechanism to cause references
to gl_VertexID and gl_InstanceID to use the gl_VertexIndex and
gl_InstanceIndex symbol.
When using GL_EXT_vulkan_glsl_relaxed, check to see if a
uniform already exists in the block uniform block, and if so,
ensure they are the same type. Otherwise, avoid growing the block
with a duplicate.
MINGW_HAS_SECURE_API can be defined as 0, but this will be ignored here without this change.
Without these *_s "safe" functions, this code will also build on Windows XP.
Full vector and fully specified vector swizzle stores are not affected by this change, only partial swizzles ie swizzles with fewer components than the vector being stored to.
Previously the vector being stored to loaded and any components not specified in the swizzle were used to create a full store to the vector.
While this change generates more SPIR-V instructions, it is necessary for correctness.
Fixes#2518.
Fix OpImageRead result type when compiling HLSL
- Per the Vulkan spec, OpImageRead must return a 4-component vector always. When compiling HLSL, loads from a RWTexture of a template type with < 4 components would incorrectly generate an OpImageRead with a < 4 component result, resulting in validation errors.
- This was previously fixed for OpImageFetch in commit 4425f24; this commit does the same thing for OpImageRead.
- Added associated tests and expanded existing image fetch tests to check all the different types of textures, in both float and int incarnations, for completeness.
- Update other HLSL tests involving OpImageRead
