| const MachineOperand * | MO = nullptr ) const |
Check if MO would be a legal operand for gfx12+ packed math FP32 instructions.
Packed math FP32 instructions typically accept SGPRs or VGPRs as source operands. On gfx12+, if a source operand uses SGPRs, the HW can only read the first SGPR and use it for both the low and high operations. SrcN can be 0, 1, or 2, representing src0, src1, and src2, respectively. If MO is nullptr, the operand corresponding to SrcN will be used.
