[PATCH] D39525: [cfi-verify] Add blacklist parsing for result filtering.

[Mitch Phillips via Phabricator via llvm-commits]

hctim created this revision.
Herald added a subscriber: mgorny.

Adds blacklist parsing behaviour for filtering results into four categories:

- Expected Protected: Things that are not in the blacklist and are protected.
- Unexpected Protected: Things that are in the blacklist and are protected.
- Expected Unprotected: Things that are in the blacklist and are unprotected.
- Unexpected Unprotected: Things that are not in the blacklist and are unprotected.

`llvm-cfi-verify` now can optionally be invoked with a second command line argument, which specifies the blacklist file that the binary was built with.

Current `-fsanitize=cfi-vcall,cfi-icall` statistics for chromium:

  Expected Protected: 100375 (69.00%)
  Unexpected Protected: 12171 (8.37%)
  Expected Unprotected: 16207 (11.14%)
  Unexpected Unprotected (BAD): 16726 (11.50%)
