[Sami Tolvanen via Phabricator via cfe-commits]

samitolvanen updated this revision to Diff 427764.
samitolvanen added a comment.

Based on LKML feedback:

- Fixed a bug in `Twine` usage.
- Changed AArch64 to encode register information into the ESR and dropped `.kcfi_traps` generation for the arch.
- Changed X86 to generate valid instructions for the type data.
- Dropped the `.kcfi_types` section entirely.
