steakhal updated this revision to Diff 432525.
steakhal retitled this revision from "[analyzer] Drop the unused
'analyzer-opt-analyze-nested-blocks' cc1 flag" to "[analyzer] Deprecate the
unused 'analyzer-opt-analyze-nested-blocks' cc1 flag".
steakhal edited the summary of this revision.
steakhal added a comment.
- Rebase on top of D126215 <https://reviews.llvm.org/D126215>
- Accept the flag with a warning, rather than erroring out.
