Eugene.Zelenko created this revision.
Eugene.Zelenko added reviewers: hans, aaron.ballman.
Eugene.Zelenko added a subscriber: cfe-commits.
Eugene.Zelenko set the repository for this revision to rL LLVM.
Autos are also used for pointer variables assigned via casts or memory
allocation. Patch includes other minor cleanups.
Build and regressions were fine on RHEL 6.
