[clang] [clang][OpenMP][NFC] Anchor "bar" CHECK-LABELs on the function definition (PR #232628)

[Bill Wendling via cfe-commits]

https://github.com/isanbard created https://github.com/llvm/llvm-project/pull/232628

ordered_doacross_codegen.cpp and parallel_for_simd_codegen.cpp use a bare "bar" as a CHECK-LABEL. That also matches the ModuleID and source_filename lines when the source path contains "bar" (e.g. a home directory like /home/isanbard), which splits the input at the wrong place and makes the tests fail. Match the define of @_Z3barv instead.

Subject: [PATCH] [clang][OpenMP][NFC] Anchor "bar" CHECK-LABELs on the
 function definition

ordered_doacross_codegen.cpp and parallel_for_simd_codegen.cpp use a
bare "bar" as a CHECK-LABEL. That also matches the ModuleID and
source_filename lines when the source path contains "bar" (e.g. a home
directory like /home/isanbard), which splits the input at the wrong
place and makes the tests fail. Match the define of @_Z3barv instead.
