Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2024-07-09T23:18:36+00:00 2024-07-09T23:18:36+00:00 venkataram-nv vedavamadath@nvidia.com 2024-07-09T23:18:36+00:00 urn:sha1:0e6c5c518953141f31c09e5f10d3939054f9b1ee This extends the code for handling uninitialized output parameters. Still needs to handle generic templates and assignment of uninitialized values more carefully. The file containing the relevant code are now in source/slang/slang-ir-use-uninitialized-values.cpp rather than the previous source/slang/slang-ir-use-uninitialized-out-param.h and the top-level function is now checkForUsingUinitializedValues. Additionally a rudimentary test shader has been added for this case, which replaces the old file for out params only; tests/diagnositcs/uninitialized-out.slang becomes tests/diagnositcs/uninitialized.slang. What this does not implement (could be future PRs): * Checking uninitialized fields within constructors * Partially uninitialized values with respect to data structure (e.g. arrays/structs/vector types) * Partially uninitialized values with respect to control flow (e.g. if/else/loop) 2024-02-01T21:26:03+00:00 Yong He yonghe@outlook.com 2024-02-01T21:26:03+00:00 urn:sha1:f370947c63bca707b9cfde7b18e67298f5fbace3 * FP16 atomics for RWByteAddresBuffer, fp32 atomics for images. * Fix spelling. * Add overload. * Fix test failures. --------- Co-authored-by: Yong He <yhe@nvidia.com> 2023-10-04T18:20:35+00:00 Yong He yonghe@outlook.com 2023-10-04T18:20:35+00:00 urn:sha1:ac886fd3e329a9599ed1ac7a6d8b26ca5821046c * SPIRV compiler performance fixes. * Cleanup. * update project files * Cleanup debug code. * Make redundancy removal non-recursive. --------- Co-authored-by: Yong He <yhe@nvidia.com> 2023-08-31T20:49:40+00:00 Yong He yonghe@outlook.com 2023-08-31T20:49:40+00:00 urn:sha1:cc412af89e54b04ead508ca84825a18d001b92d0 * Fix atomics intrinsics and buffer layout lowering. * Fix. * Add more test. * Fix. --------- Co-authored-by: Yong He <yhe@nvidia.com> 2023-05-03T03:29:38+00:00 Yong He yonghe@outlook.com 2023-05-03T03:29:38+00:00 urn:sha1:d52376a65f37fcbbb67428b917fd3819436b6dfb * Various dxc/fxc compatibility fixes. * Cleanup. * Fix test cases. * Fix comments. --------- Co-authored-by: Yong He <yhe@nvidia.com> 2023-04-21T06:05:49+00:00 Ellie Hermaszewska ellieh@nvidia.com 2023-04-21T06:05:49+00:00 urn:sha1:deb130645e8538eed8fb9f682de64e2dd329473d * Add warning for returning without initializing out parameter * Add unused prelude function to squash uninitialized out variable warnings 2023-04-14T15:12:14+00:00 Yong He yonghe@outlook.com 2023-04-14T15:12:14+00:00 urn:sha1:168c58389e9155312a8cef88d986a4ceee5a511e * Diagnose on using uninitialized `out` param. * Hack to allow `out Vertices<T>`. * Fix. --------- Co-authored-by: Yong He <yhe@nvidia.com>
