Jakob Stoklund Olesen c26e2e6221 Permit remat of partial register defs when it is safe. ... An instruction may define part of a register where the other bits are undefined. In that case, it is safe to rematerialize the instruction. For example: %vreg2:ssub_0<def> = VLDRS <cp#0>, 0, pred:14, pred:%noreg, %vreg2<imp-def> The extra <imp-def> operand indicates that the instruction does not read the other parts of the virtual register, so a remat is safe. This patch simply allows multiple def operands for the virtual register. It is MI->readsVirtualRegister() that determines if we depend on a previous value so remat is impossible. llvm-svn: 138953		2011-09-01 18:27:51 +00:00
