Stephen Lin	771e0ab32a	Disambiguate function names in some CodeGen tests. (Some tests were using function names that also were names of instructions and/or doing other unusual things that were making the test not amenable to otherwise scriptable pattern matching.) No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186621 91177308-0d34-0410-b5e6-96231b3b80d8	2013-07-18 22:29:15 +00:00
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

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

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.
