Evan Cheng 35ff79370b 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. llvm-svn: 43192		2007-10-19 21:23:22 +00:00
