New Revision: b56488c8790a8fc3cd0fc97c74999b54afcd9176

URL: https://github.com/llvm/llvm-project/commit/b56488c8790a8fc3cd0fc97c74999b54afcd9176
DIFF: https://github.com/llvm/llvm-project/commit/b56488c8790a8fc3cd0fc97c74999b54afcd9176.diff

LOG: [libc++] Improve the output of the generated-output CI job (#68903)

The step that checked for ignore_format.txt being consistent with the
tree wouldn't print any explicit diagnostic when failing, which led to
confusion. After this patch, an explicit diagnostic will be printed by
the job along with the required diff to ignore_format.txt.
