From 02239847305c20b3bcd6928516c7013c298e270f Mon Sep 17 00:00:00 2001 From: Joseph Huber Date: Sun, 10 Aug 2025 12:12:20 -0500 Subject: [PATCH] [libc] Expose the AMDGPU code object version Summary: People might want to modify this to run on older machines. Expose this so it can be set with `-DRUNTIMES_amdgcn-amd-amdhsa_LIBC_GPU_CODE_OBJECT_VERSION`. --- libc/cmake/modules/prepare_libc_gpu_build.cmake | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/libc/cmake/modules/prepare_libc_gpu_build.cmake b/libc/cmake/modules/prepare_libc_gpu_build.cmake index f8f5a954e5e91..df1de1454c3eb 100644 --- a/libc/cmake/modules/prepare_libc_gpu_build.cmake +++ b/libc/cmake/modules/prepare_libc_gpu_build.cmake @@ -100,12 +100,10 @@ if(NOT TARGET libc.utils.gpu.loader AND gpu_loader_executable) ) endif() -if(LIBC_TARGET_ARCHITECTURE_IS_AMDGPU) - # The AMDGPU environment uses different code objects to encode the ABI for - # kernel calls and intrinsic functions.
