  "message": "Subzero: Legalize FP constants directly into memory operands.\n\nPreviously, the legalize() function would always force a floating point constant into an xmm register before it could be used in an instruction.  This uses an extra register unnecessarily when the instruction allows a memory operand for that operand.\n\nWe improve this by lowering the FP constant operand to an OperandX8632Mem that wraps a ConstantRelocatable representing the label for the constant pool entry, e.g. [.L$float$0].  (This may end up being copied into an xmm register if the instruction doesn\u0027t allow a memory operand for that operand.)\n\nBUG\u003d https://code.google.com/p/nativeclient/issues/detail?id\u003d4095\nR\u003djvoung@chromium.org\n\nReview URL: https://codereview.chromium.org/1163943005\n",
