2023-04-13Matrix swizzle writes (#2713)Ellie Hermaszewska
* Add a bunch of builder emit wrappers for constant indices To avoid cluttering any calling code with int instruction construction * Matrix swizzle stores Closes https://github.com/shader-slang/slang/issues/2512 * Matrix swizzle store tests * Squash vs warnings * Select scalar for singular swizzles * Test singular swizzle materialization * Use IRIntegerValue over UInt for IR wrappers * Correct size of swizzle vector type * Remove variable shadowing

2023-04-11Implement FileCheck tests for several test commands (#2747)Ellie Hermaszewska
* Add missing expected.txt for test * Diagnostics -> StdWriters in render test * Allow specifying several test prefixes to run `slang-test -- tests/foo tests/bar` * Squash warnings in some tests * Enable gfx debug layer in gfx test util Makes this issue present consistently: https://github.com/shader-slang/slang/issues/2766 * Allow DebugDevice to return interfaces instantiated by the debugged object * Check that we actaully have a shader cache for shader cache tests * Implement FileCheck tests for several test commands - SIMPLE, SIMPLE_EX - SIMPLE_LINE - REFLECTION, CPU_REFLECTION - CROSS_COMPILE It does not currently support the render tests or the COMPARE_COMPUTE commands It is invoked by adding `(filecheck=MY_FILECHECK_PREFIX)` to the test command, for example TEST:CROSS_COMPILE(filecheck=SPIRV): -target spirv-assembly * Move LLVM FileCheck interface to slang-llvm * Neaten slang-test tests * Refine handling of expected output in slang-test * Add example FileCheck buffer test * Add cuda-kernel-export tests Which were waiting on FileCheck * Bump vs project files * Make createLLVMFileCheck_V1 return a void* rather than specifically an IFileCheck * Remove use of CharSlice from filecheck interface * Bump slang-llvm version --------- Co-authored-by: jsmall-nvidia <jsmall@nvidia.com>
