5// 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:
6// RUN: %clang_profgen -O2  -fcoverage-mapping  -o %t.2 %s
7// RUN: env LLVM_PROFILE_FILE=%t.2.profraw %run %t.2
8// RUN: llvm-profdata merge -o %t.2.profdata %t.2.profraw

10// Check covmap is not garbage collected when GC is turned on with BFD linker. Due to the bug mentioned above, we can only
11// do the check with objdump:
12// RUN: %clang_profgen -O2  -fcoverage-mapping -Wl,--gc-sections -o %t.3 %s
13// RUN: llvm-objdump -h %t.3 | FileCheck --check-prefix COVMAP %s
