* Legalizer optimize a pair of div / mod to a call to divrem libcall if they areEvan Cheng2012-10-121-12/+34
| | | | | | | | | | | not legal. However, it should use a div instruction + mul + sub if divide is legal. The rem legalization code was missing a check and incorrectly uses a divrem libcall even when div is legal. rdar://12481395 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165778 91177308-0d34-0410-b5e6-96231b3b80d8
