For example, bazel test --config=fuzzer --test_output=all //common:check_test results in the following output.

...

  1.  <eof> parser at end of file

  2.  Code generation

  3.  Running pass 'Function Pass Manager' on module 'external/llvm-project/llvm/lib/Support/ARMAttributeParser.cpp'.

  4.  Running pass 'Live Variable Analysis' on function '@_ZN4llvm18ARMAttributeParser7handlerEmRb'

bazel's per_file_copt can be used to exclude llvm/ sources from fuzzing as a workaround:

bazel test --config=fuzzer --per_file_copt=-llvm/.*@-fno-sanitize=fuzzer --test_output=all toolchain/driver:driver_fuzzer

Workaround LLVM compiler bug when fuzzing. (#1340)
c62b0d1 
Fixes #1173

There is a long standing crash in the LLVM code generator that we manage
to hit when fuzzing. Disable the fast instruction selector in the
fuzzing config to avoid it. I reduced a test case and filed the LLVM bug
here: llvm/llvm-project#56133
