Eric Christopher	bcaedb5ce0	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 llvm-svn: 129842	2011-04-20 01:19:45 +00:00
Eric Christopher	bb14f65672	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. llvm-svn: 123864	2011-01-20 00:29:24 +00:00

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.
