MaskRay added a comment. I have tested the following configurations on x86_64-linux-gnu and I don't find a difference.
CC=/tmp/RelA/bin/clang CXX=/tmp/RelA/bin/clang++ $CC -c a.c $CC a.o '-###' &> a/c.raw.txt $CC a.o --rtlib=compiler-rt --unwindlib=none '-###' &> a/c.rt.none.txt $CC a.o --rtlib=compiler-rt --unwindlib=libgcc '-###' &> a/c.rt.libgcc.txt $CC a.o --rtlib=compiler-rt --unwindlib=libunwind '-###' &> a/c.rt.libunwind.txt $CXX a.o '-###' &> a/cc.raw.txt $CCX a.o --rtlib=compiler-rt --unwindlib=none '-###' &> a/cc.rt.none.txt $CCX a.o --rtlib=compiler-rt --unwindlib=libgcc '-###' &> a/cc.rt.libgcc.txt $CCX a.o --rtlib=compiler-rt --unwindlib=libunwind '-###' &> a/cc.rt.libunwind.txt I'd hope we reduce the usage of `UnspecifiedLibGcc` as it has the tricky `--as-needed` implication. I think the idea is that for C (no exceptions, so no `_Unwind_Resume` at the end of non-catch handlers), `libgcc_s.so.1` is usually unneeded, so `--as-needed` can likely result in one fewer DT_NEEDED... This optimization probably does not have much value. So if you want to add a condition, please test mingw triple instead of testing `RLT == ToolChain::RLT_Libgcc` Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D98023/new/ https://reviews.llvm.org/D98023 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
