2024-06-08SPIRV `Block` decoration fixes. (#4303)Yong He
* SPIRV `Block` decoration fixes. - SPIRV does not allow duplicate `Block` decorations. So we shouldn't be generating them. - Also fixes duplication of OpName. - SPIRV and HLSL do not allow ConstantBuffer with trailing unsized arrays. Added a check in the front-end against such code. * Convert failing cross-compile tests to filecheck. --------- Co-authored-by: Jay Kwak <82421531+jkwak-work@users.noreply.github.com>

2024-06-07Precompute UIntSet from individual capabilities inside generator (#4269)ArielG-NV
* fixes: #4163 Precompute UIntSet from individual capabilities inside generator (removes intermediate form of capabilities). note: 1. I still expand capabilities which are missing `target` and `stage` atoms. * fix compile warning<->error with clang * address review preallocate the pregenerated UIntSet's * disable incorrect warning of 'unreachable code' The warning is wrong since, when `out` has 0 elements (does not start `for` loop), the `return` is reached. * fix clang warnings 1. use unsigned long for the buffer serializer 2. braces around scalar init * address review added work around to avoid warning with `for(...) return; return;` pattern `else if constexpr` addition instead of cascading blocks * push fix for use of `_BitScanForward` * cleanup * move around assert for proper checking * syntax error * use SLANG_ASSERT instead of assert * test for why SLANG_ASSERT caused CI to fail with linux-arm builds * test if `SLANG_ASSERT` really is causing a build issue for linux-arm

2024-06-06Remove unnecessary call to __requireComputeDerivative (#4283)Jay Kwak
* Remove unnecessary call to __requireComputeDerivative When SPIR-V uses operators whose name has a keyword, "Implicit", they require calling a function "__requireComputeDerivative()". When it uses "Explicit", the function doesn't need to be called.

2024-06-04Add APIs to get profile of compile time (#4242)kaizhangNV
* Add APIs to get profile of compile time Add serial time measurement Add profiler to measure lots of stages in slang compilation, and it can accumulate the time spent in each thread in multi-threads case and finally report a serial timing info. * Add invocation times to the profiler * Simplify the profiler and provide a 'clear' option Change the profiler design to only return the thread_local profiler to user. We create a ISlangProfiler interface to carry the thread_local variable PerformanceProfilerImpl profiler to user. In addition, we provide a new option in the input parameter to control whether or not user want to clear the previous profile data. So spGetCompileProfile() can always returns a fresh new profiling data. * Change to use slang container List Stop using std::vector, instead use slang's container List. Generate a UUID for ISlangProfiler

2024-05-28Print memory leak info in Debug build of slangc.exe (#4210)Jay Kwak
When memory leak is detected, this commit will dump the information about the memory leak. This feature is available only in Debug build on Windows platform. Also note that the message will not be printed on the client applications that use slang.dll, because the printing happens as a part of slangc.exe not slang.dll. I found a bug that Slang::StdWriters was closing `stdout` and `stderr` in its destructor, which prevented Crt functions to print the messages to `stdout` and `stderr`.
