Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290 2009-09-09 01:54:48 +02:00			`; RUN: llc < %s -mtriple=x86_64-linux -relocation-model=static \| grep xmm \| count 2`
Enable rematerialization of constants using AliasAnalysis::pointsToConstantMemory, and knowledge of PseudoSourceValues. This unfortunately isn't sufficient to allow constants to be rematerialized in PIC mode -- the extra indirection is a complication. llvm-svn: 54000 2008-07-25 02:02:30 +02:00
