Chris Lattner 63602fb868 Do not CopyFromReg physregs for live-in values. Instead, create a vreg for ... each live in, and copy the regs from the vregs. As the very first thing we do in the function, insert copies from the pregs to the vregs. This fixes problems where the token chain of CopyFromReg was not enough to allow reordering of the copyfromreg nodes and other unchained nodes (e.g. div, which clobbers eax on intel). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21932 91177308-0d34-0410-b5e6-96231b3b80d8		2005-05-13 07:38:09 +00:00
