The recent expression type changes still need more discussion, which will happen on phabricator or on the mailing list. The precise list of commits reverted are: - "Refactor division generation code" - "[NFC] Generate runtime checks after the SCoP" - "[FIX] Determine insertion point during SCEV expansion" - "Look through IntToPtr & PtrToInt instructions" - "Use minimal types for generated expressions" - "Temporarily promote values to i64 again" - "[NFC] Avoid unnecessary comparison for min/max expressions" - "[Polly] Fix -Wunused-variable warnings (NFC)" - "[NFC] Simplify min/max expression generation" - "Simplify the type adjustment in the IslExprBuilder" Some of them are just reverted as we would otherwise get conflicts. I will try to re-commit them if possible. llvm-svn: 272483
