// BFD linker older than 2.26 has a bug that per-func profile data will be wrongly garbage collected when GC is turned on. We only do end-to-end test here without GC:
// RUN: %clang_profgen -O2 -fcoverage-mapping -o %t.2 %s

// Check covmap is not garbage collected when GC is turned on with BFD linker. Due to the bug mentioned above, we can only
// do the check with objdump:
