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
Martin Storsjo	d2bdcd6f8a	[Analysis] Validate the return type of s(n)printf like libcalls ... If the sprintf function is static (as on mingw-w64, where many stdio functions are static inline wrappers), earlier optimization passes could optimize out the return value altogether, and make it void, which could break optimizations of this libcall that touch the return value. This fixes the issue discussed in PR37408 for the sprintf function.
