* Previously the offset was only updated with EOpIndexDirectStruct, but we also
need to update it for the other index types into arrays, and when expanding an
aggregate reached after dereferencing.
* Changed unit tests to only record known the validation pass/fail
status
* errors are output as part of the failure message if the result is
unexpected
* can turn off validation for each test individually
* Moved some SPV_KHR_vulkan_memory_model tests to be compiled for Vulkan
1.1
Without this commit, if the XfbStride was explicitly set, the
decoration was added twice on the shader.
v2 (changes after Jonh Kessenich first review)
* Simplified by just removing the firs assignment
* Removed assert
including SPV generation using SPV_EXT_fragment_invocation_density.
This is an alias of the functionality in SPV_NV_shading_rate, and thus in some
cases we can only have one set of the tokens present (switch statements), so
we have picked the EXT version. This required updating the expected test
results for SPV_NV_shading_rate.
Also updated the known-good for spirv-headers so that the validator in
spirv-tools knows about the new extension.
This change adds unary conversion folding when the source is a constant.
This fixes an ISV issue whereby:
```
const float16_t f = float16_t(42.0);
```
Wouldn't compile because the conversion operator would always produce an
EvqTemporary when it could have produced an EvqConst.
I've also added a test case that proves out that all basic-type to
basic-type conversions work.
Adjusted a test not to use c register for
a structured buffer, they are supposed to
use t registers
Added comments with hints for what are the
register types are used for.
If a block has assigned a XfbOffset it is assumed that it would
inherit the current global XfbBuffer. This commit fixes two use cases:
1) Getting the members of a Block with a XfbOffset to be assigned an
offset, as explained on GLSL 4.60 spec, section "4.4.2 Output
Layout Qualifiers", subsection "Transform Feedback Layout
Qualifiers".
2) Compute properly an error on overlapping ranges if a block is
assigned a XfbOffset and one of it members is assigned a explicit
one. This gets working because when the members of a block get
assigned a Offset/Buffer at fixBlockXfbOffsets, then the block is
deassigned the Offsets, so ranges are computed only with the block
members.
BTW, this is already done when redeclaring block builtins.
Fixes#1535
