Some compiler-rt tests check for the presence of the compiler accepting -fno-lto to add that flag. Otherwise some tests don't link due to -flto mismatch between compiling and linking. $ cmake ... -DLLVM_ENABLE_LTO=Thin ... $ ninja projects/compiler-rt/lib/sanitizer_common/tests/Sanitizer-x86_64-Test.exe previously failed, now links.
