GitHub action benchmark (#4804)

2024-08-13T18:44:19+00:00

Adds a new Github CI action for benchmarking the slangc compiler on the MDL shaders. For now, the results are only dumped to the output of the CI, which can be later viewed through raw logs. The next step is to use github-action-benchmark to push these results into a page which will show the benchmark results over time as commits are pushed.

Use memcpy to replace strncpy_s (#4270)

Use memcpy to replace strncpy_s in SlangProfiler::SlangProfiler to fix the error in Windows.

Add APIs to get profile of compile time (#4242)

2024-06-05T01:24:12+00:00

* 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

Fix race-condition and visual artifacts issues (#4152)

2024-05-11T00:32:09+00:00

* Fix race-condition and visual artifacts issues In PerformanceProfiler::getProfiler() we return a static object for the profiler implementation, this is not thread-safe, so change it to thead_local. There is still some visual artifacts when using slang as the shading language. We don't know the root cause yet, but found out it's related to our loop inversion algorithm. So stage this feature for now, and turn it into an internal option and default off. We will re-enable it after more investigation on this optimization. File an new issue 4151 to track it. * Add '-loop-inversion' to the few tests
