Evan Cheng 66f7163545 Local spiller optimization: ... Turn a store folding instruction into a load folding instruction. e.g. xorl %edi, %eax movl %eax, -32(%ebp) movl -36(%ebp), %eax orl %eax, -32(%ebp) => xorl %edi, %eax orl -36(%ebp), %eax mov %eax, -32(%ebp) This enables the unfolding optimization for a subsequent instruction which will also eliminate the newly introduced store instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43192 91177308-0d34-0410-b5e6-96231b3b80d8		2007-10-19 21:23:22 +00:00
