Evan Cheng 32dfbeada7 EXTRACT_SUBREG coalescing support. The coalescer now treats EXTRACT_SUBREG like ... (almost) a register copy. However, it always coalesced to the register of the RHS (the super-register). All uses of the result of a EXTRACT_SUBREG are sub- register uses which adds subtle complications to load folding, spiller rewrite, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42899 91177308-0d34-0410-b5e6-96231b3b80d8		2007-10-12 08:50:34 +00:00
