* Fix 7441: CUDA boolean vector layout to use 1-byte elements
Boolean vectors (bool1, bool2, bool3, bool4) were incorrectly implemented
as integer-based types using 4 bytes per element instead of actual 1-byte
boolean elements on CUDA targets.
Changes:
- Update CUDA prelude to define boolean vectors as structs with bool fields
instead of typedef aliases to integer vectors
- Implement CUDALayoutRulesImpl::GetVectorLayout to use 1-byte alignment
for boolean vectors, matching actual CUDA memory layout behavior
- Update make_bool functions to populate struct fields correctly
This ensures boolean vectors have the same memory layout as bool[4] arrays:
- bool1: 1 byte (was 4 bytes)
- bool2: 2 bytes (was 8 bytes)
- bool3: 3 bytes (was 12 bytes)
- bool4: 4 bytes (was 16 bytes)
Fixes memory layout mismatch between Slang reflection API and actual
CUDA compilation, achieving 75% memory savings for boolean vector usage.
* Fix CI issues -
Add and update associated functions and operators
* Make boolX same as uchar
* Use align construct on struct for boolX
* Improve Test case for robust alignment checks
* Formatting
* Disable selected slangpy tests
* add metal check which is slightly different than cuda
* Test-1
* Test-2
* Test-3
* Test-4
* ReflectionChange
* cleanup and update
* _slang_select with plain bool is needed for reverse-loop-checkpoint-test

* Improvements to HLSLToVulkanLayoutOptions.
* WIP vk-shift-* with HLSL like binding.
Detecting clashes.
* Shift example seems to be working correctly.
One oddness is that "used" data is now reflected, as we only enable for D3D shader resource types. Now we use those with inferred VK mode they appear.
* Implicit seems to work.
* Disable inference with Sampler/CombinedTextureSampler.
I guess? we could just use the HLSL texture register binding to infer.
* Report overlapping ranges in diagnostic.
The hlsl-to-vulkan-shift-diagnostic result might be surprising but it is correct, because u is automatically laid out so consumes DescriptorSlot 0, but that's already consumed by c.
* First attempt at array layout with infer on Vulkan.
* Fix the vulkan shift output.
* Array example.
