Eli Bendersky	107db21c2b	Similar to bitcast, treat addrspacecast as a foldable operand. ... Added a test sink-addrspacecast.ll to verify this change. Patch by Jingyue Wu. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209343 91177308-0d34-0410-b5e6-96231b3b80d8	2014-05-22 00:02:52 +00:00
Manuel Jacob	f8909fa140	CodeGenPrep: sink extends of illegal types into use block. ... Summary: This helps the instruction selector to lower an i64 * i64 -> i128 multiplication into a single instruction on targets which support it. This is an update of D2973 which was reverted because of a bug reported as PR19084.
