Those headers are generated by LLVM-libc for the GPU triple.\n\nA concrete example is the amdgcn runtimes build:\n\n -DLLVM_RUNTIME_TARGETS\u003d\u0027default;amdgcn-amd-amdhsa\u0027\n -DRUNTIMES_amdgcn-amd-amdhsa_LLVM_ENABLE_RUNTIMES\u003d\u0027compiler-rt;libc\u0027\n -DRUNTIMES_amdgcn-amd-amdhsa_RUNTIMES_USE_LIBC\u003dllvm-libc\n\nEven though `libc` is configured before `compiler-rt`, both sets of\ntargets live in the same ninja graph and race each other. Ninja can\nstart compiling `compiler-rt/lib/profile/InstrProfiling.c` before\nLLVM-libc has finished generating its GPU `string.h`, and even when\nhdrgen has finished, the profile compile needs `-isystem` pointing at\nthe generated header tree.\n\nUse the runtimes-side libc-provider abstraction in\n`runtimes/cmake/Modules/HandleLibC.cmake`:\n\n - at compiler-rt top level, `include(HandleLibC)` when\n `LLVM_RUNTIMES_BUILD` is set, so all compiler-rt subcomponents can\n reuse the `runtimes-libc-*` targets. `libcxx` / `libcxxabi` /\n `libunwind` include it the same way at their top-level CMakeLists.\n - in `compiler-rt/lib/profile/CMakeLists.txt`, when the GPU build\n sees the sibling `runtimes-libc-headers` target, pass it through\n `LINK_LIBS` of `add_compiler_rt_runtime(clang_rt.profile ...)`.\n\nIn the `llvm-libc` case this pulls in LLVM-libc\u0027s `libc-headers`\n(`-isystem \u003cbuild\u003e/include/\u003ctriple\u003e`), waits for\n`generate-libc-headers`, and adds `-nostdlibinc` so the profile compile\ndoes not consult host C library paths.\n\nThe dependency is added only when `COMPILER_RT_GPU_BUILD` is on and the\nsibling `runtimes-libc-headers` target actually exists, so host\ncompiler-rt builds, standalone compiler-rt builds, and runtimes builds\nwithout LLVM-libc selected are unchanged.\n\n`add_compiler_rt_runtime` passes `LINK_LIBS` to\n`target_link_libraries(\u003clibname\u003e PRIVATE ...)`, so the include path is\nused when compiling the profile target itself but is not propagated to\ndownstream consumers of `libclang_rt.profile.a`.\n\nRelated: PR #177665.\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: e0b4a7063f78d36ffa5679e1d0e564a3668db1f0\n" }, { "commit": "27e20cd35603c9b403f3fee7a9d50df04a0bc006", "tree": "8f5a6d8bdd470ff41128841b5c251212c3baeb75", "parents": [ "df9fb83ee751cc9ac0326953f9237ab7a955115b" ], "author": { "name": "PiJoules", "email": "leonardchan@google.com", "time": "Tue Apr 21 19:09:11 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Apr 21 19:10:56 2026" }, "message": "[compiler-rt][asan] Add asan checks for __builtin_assume_dereferencable (#190871)\n\nThis checks that the range covered by this intrinsic is dereferencable.\nSpecifically it checks for `llvm.assume` intrinsics using the\n`dereferencable` operator bundle and just asserts the shadow for this\nrange is zero.\n\nThe bulk of this PR was made by gemini but it was thoroughly edited and\nreviewed to the best of my ability.\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: bf8cf4b7b31b956ea4dfec93b0b4d77b359b188b\n" }, { "commit": "df9fb83ee751cc9ac0326953f9237ab7a955115b", "tree": "d22dceabb8b268c618635f5010e93281e76d206b", "parents": [ "3c27cdad271a614e397adb2a63930d7a91036eac" ], "author": { "name": "Brian Cain", "email": "brian.cain@oss.qualcomm.com", "time": "Tue Apr 21 15:20:01 2026" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Tue Apr 21 15:26:12 2026" }, "message": "[compiler-rt] Implement __clear_cache for Hexagon (#188411)\n\nAdd Hexagon support to compiler-rt\u0027s __clear_cache implementation.
