When the path is registered as SYSTEM, it is used with `-isystem` option not `-I` option and it gets less searching order on MacOS. When spirv.h is installed on the system directory, it will end up using the system installed spirv.h, which is most likely an older version than we should use. 2025-09-17T19:27:57+00:00 Gangzheng Tong tonggangzheng@gmail.com 2025-09-17T19:27:57+00:00 urn:sha1:58060d2f7e86427124551f3f6edcf05bf6e4d229 This PR resolves a configuration conflict where the SLANG_ENABLE_SPIRV_TOOLS_MIMALLOC option was defined twice with different defaults, causing user settings to be overridden. Changes: - Removed duplicate definition in external/CMakeLists.txt that only applied to WIN32 - Define default in main CMakeLists.txt - ON by default for Windows - OFF by default for other platforms (still need to resolve crashes so set it to `OFF` for now) Preserved user configuration - explicit -DSLANG_ENABLE_SPIRV_TOOLS_MIMALLOC=value settings are now properly respected Related to https://github.com/shader-slang/slang/issues/8158 --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> 2025-09-16T01:46:59+00:00 Gangzheng Tong tonggangzheng@gmail.com 2025-09-16T01:46:59+00:00 urn:sha1:8ad0ae17880480abe587617c997ab28b23abc146 * Added optional mimalloc integration for SPIRV-Tools to improve compilation performance * Cloning `mimalloc` repo to external/ on demand during cmake config * Enabled by default on Windows, configurable via `SLANG_ENABLE_SPIRV_TOOLS_MIMALLOC` CMake option, to enable static mimalloc build in spirv-tools. * There are some crashes in Linux and Mac with static mimalloc enabled, likely due to the system malloc and mimalloc mixed usage. This might be expected as mimalloc in spirv-tools is not extensively tested according to https://github.com/KhronosGroup/SPIRV-Tools?tab=readme-ov-file#dependency-on-mimalloc. So by default only Windows has this enabled.
