This allows specifying a fixed host linker version during Clang configuration (e.g. -DHOST_LINK_VERSION=1249), bypassing the default auto-detection. This is useful for hermetic packaging scripts where the auto-detected host linker might differ from the intended target linker, and we do not want certain features to be enabled that depends on the host linker version -- e.g. https://github.com/llvm/llvm-project/issues/203385 >From bb50102862e6db9921fdfd7ea5ee14d49d8a0e5b Mon Sep 17 00:00:00 2001 From: Yue She <[email protected]> Date: Mon, 15 Jun 2026 10:21:10 -0400 Subject: [PATCH] [clang][CMake] Make HOST_LINK_VERSION a CACHE option on Darwin --- clang/CMakeLists.txt | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/clang/CMakeLists.txt b/clang/CMakeLists.txt index db79131af9c1f..cd7ba53b03061 100644 --- a/clang/CMakeLists.txt +++ b/clang/CMakeLists.txt @@ -407,9 +407,12 @@ if (LLVM_COMPILER_IS_GCC_COMPATIBLE) endif () # Determine HOST_LINK_VERSION on Darwin. -set(HOST_LINK_VERSION) -if (APPLE AND NOT CMAKE_LINKER MATCHES ".*lld.*") +set(HOST_LINK_VERSION "" CACHE STRING "Host linker version on Darwin") +if (APPLE AND NOT HOST_LINK_VERSION AND NOT CMAKE_LINKER MATCHES ".*lld.*") get_darwin_linker_version(HOST_LINK_VERSION) + set(HOST_LINK_VERSION "${HOST_LINK_VERSION}" CACHE STRING "Host linker version on Darwin" FORCE) +endif() +if (HOST_LINK_VERSION) message(STATUS "Host linker version: ${HOST_LINK_VERSION}") endif() _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
