| * Generic 64bit-to-32bit unary operation. Provide an "instr" line |
| * that specifies an instruction that performs "result = op a0/a1", where |
| * "result" is a 32-bit quantity in a0. |
| * |
| * For: long-to-float, double-to-int, double-to-float |
| * If hard floating point support is available, use fa0 as the parameter, except for |
| * long-to-float opcode. |
| * (This would work for long-to-int, but that instruction is actually |
| * an exact match for OP_MOVE.) |
