* Fix broken -emit-spirv-via-glsl test option (#7091)sricker-nvidia2025-05-16
| | | | | | | | | | | | | | | | | | | | | | | | Fixes issue #6898 The -emit-spirv-via-glsl slang-test option has been broken for some amount of time. Tests that were using it were operating as if using -emit-spirv-directly, leading to many duplicated tests. After fixing the test option, there were an number of errors that appeared as a result. This change fixes the broken test option and the resulting test errors. Some of the test errors revealed some legitimate issues, such as: -The GLSL bitCount instrinsic only supports 32-bit integers and requires emulation for other bit widths. -Emitting GLSL 8-bit and 16-bit glsl integer types did not emit the proper extension requirements -Emitting GLSL and casting for 16-bit integers was missing a closing parenthesis. -Missing profile for GL_EXT_shader_explicit_arithmetic_types -Missing toType cases for UInt8/Int8 for the kIROp_BitCast case in tryEmitInstExprImpl.
* Implement spec const for generic parameter (#7121)kaizhangNV2025-05-15
Close #6840. This PR add supports to use specialize constant in generic parameter, and that parameter can also be used as array size, e.g. following code should work: ``` struct MyStruct<let N: int> { float buffer[N]; } MyStruct<SpecConstVar> s; ``` - Loose the restriction from Link-Time to SpecializationConstant when extract generic argument - Tweak the logic of how we decide whether a inst is hoistable. Besides checking existing hoistable flag of each IRInst, when we detect a IRInst's type is SpecConstRateType, we will treat that inst hoistable. Because IRInst in global scope can be deduplicated, and every SpecConstRateType inst should be in the global scope or IRGeneric scope (which will be at global scope after specialization). - Remove the SpecConstIntVal to IRInst map in IR lowering logic, because we already have way to deduplicate the global scope IR.
