If the arch is P8, we will select XFLOAD to load the floating point, and then, expand it to vsx and non-vsx X-form instruction post RA. This patch is trying to convert the X-form to D-form if it meets the requirement that one operand of the x-form inst is the special Zero register, and another operand fed by add inst. i.e. y = add imm, reg LFDX. 0, y --> LFD imm(reg) Reviewers: Nemanjai Differential Revision: https://reviews.llvm.org/D49007 llvm-svn: 340149
