Eric Christopher	598198edbc	Revert "Temporarily Revert "Add basic loop fusion pass."" ... The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@358552 91177308-0d34-0410-b5e6-96231b3b80d8	2019-04-17 04:52:47 +00:00
Eric Christopher	02cc44c1b9	Temporarily Revert "Add basic loop fusion pass." ... As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@358546 91177308-0d34-0410-b5e6-96231b3b80d8	2019-04-17 02:12:23 +00:00
Nikita Popov	16ca3e1017	[MergeFuncs] Generate alias instead of thunk if possible ... The MergeFunctions pass was originally intended to emit aliases instead of thunks where possible (unnamed_addr). However, for a long time this functionality was behind a flag hardcoded to false, bitrotted and was eventually removed in r309313. Originally the functionality was first disabled in r108417 due to lack of support for aliases in Mach-O. I believe that this is no longer the case nowadays, but not really familiar with this area. In the interest of being conservative, this patch reintroduces the aliasing functionality behind a default disabled -mergefunc-use-aliases flag.
