Hi Tobias and all, I can confirm instrumented builds are also broken with [ mailto:clang-runtime@15 | clang-runtime@15 ] at the moment(using `clang -fprofile-instr-generate`) because `libclang_rt.profile-x86_64.a` doesn't exist. In my opinion your suggested patch is just fine, as I believe we have to keep static files for this package: - clang's driver actually explicitly link static files for some of them: [ https://github.com/llvm/llvm-project/blob/4c6f95be29c6ce0f89663a5103c58ee63d76cda3/clang/lib/Driver/ToolChains/CommonArgs.cpp#L1070-L1072 | https://github.com/llvm/llvm-project/blob/4c6f95be29c6ce0f89663a5103c58ee63d76cda3/clang/lib/Driver/ToolChains/CommonArgs.cpp#L1070-L1072 ] - I couldn't find a recent explanation for this and all compiler-rt components, but this forum post explains why there are both static libs and shared libs: [ https://discourse.llvm.org/t/asan-static-linking-on-android/29223/3 | https://discourse.llvm.org/t/asan-static-linking-on-android/29223/3 ] (basically they use static linking to intercept only calls from the main binary and not from dependent libraries, thanks to a glibc load order behavior, but the trick doesn't work on android and other platforms so they LD_PRELOAD a shared lib). By a quick glance at the installed components I couldn't find any static library that we can remove (most of them only exist as a static library, and the others are sanitizers). Regards, Philippe
