Eric Christopher	abbbfbd672	Rewrite the expander for umulo/smulo to remember to sign extend the input ... manually and pass all (now) 4 arguments to the mul libcall. Add a new ExpandLibCall for just this (copied gratuitously from type legalization). Fixes rdar://9292577 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129842 91177308-0d34-0410-b5e6-96231b3b80d8	2011-04-20 01:19:45 +00:00
Eric Christopher	38a18261b9	If we can, lower the multiply part of a umulo/smulo call to a libcall ... with an invalid type then split the result and perform the overflow check normally. Fixes the 32-bit parts of rdar://8622122 and rdar://8774702. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123864 91177308-0d34-0410-b5e6-96231b3b80d8	2011-01-20 00:29:24 +00:00
