* Replaced uses in opcode validation of current_function()
* Added non-const accessor to function lookup in ValidationState_t
* Updated a couple bad tests due to check reordering
This CL splits the switch in ImagePass into individual validate
functions. The error messages have been updated to drop the
suffix/prefix of the opcode name since it will be displayed in the
disassembly.
Implemented Vulkan-specific rules:
- OpTypeImage must declare a scalar 32-bit float or 32-bit integer type
for the “Sampled Type”.
- OpSampledImage must only consume an “Image” operand whose type has its
“Sampled” operand set to 1.
@ehsannas had filed an issue against SPIR-V spec, concerning
Image Operands section (3.14):
Sample
A following operand is the sample number of the sample to use. Only
valid with OpImageFetch, OpImageRead, and OpImageWrite.
Relaxing the check to allow OpImageSparseRead and
OpImageSparseFetch to fix failing tests.
Re-formatted the source tree with the command:
$ /usr/bin/clang-format -style=file -i \
$(find include source tools test utils -name '*.cpp' -or -name '*.h')
This required a fix to source/val/decoration.h. It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.
Removed the check that result type of OpImageRead should be a vector4.
Will reenable/adapt once the spec is clarified on what the right
dimension should be.
