isPreISelGenericFloatingPointOpcode()

static bool isPreISelGenericFloatingPointOpcode ( unsigned  Opc )

static

Returns whether opcode Opc is a pre-isel generic floating-point opcode, having only floating-point operands.

FIXME: this is copied from target AArch64. Needs some code refactor here to put this function in GlobalISel/Utils.cpp.
