Support Vulkan memory model (#7057)

2025-05-17T02:26:44+00:00

The user can explicitly use Vulkan memory model, or it will be automatically used when cooperative-matrix is used. When vulkan memory model is used, two keywords, "Coherent" and "Volatile", are not allowed. There are many differences regarding atomic and texture but this PR has changes limited to support `globallycoherent` keyword. When variables with `globallycoherent` is used with `OpLoad`, it will use additional options, `MakePointerAvailable|NonPrivatePointer`, that will provide the same effect. For `OpStore`, it will use `MakePointerVisible|NonPrivatePointer`.

Fix broken -emit-spirv-via-glsl test option (#7091)

2025-05-16T00:01:08+00:00

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.
