| /* | |
| * Generic 32-bit "/2addr" binary operation. Provide an "instr" line | |
| * that specifies an instruction that performs "result = r0 op r1". | |
| * This could be an ARM instruction or a function call. (If the result | |
| * comes back in a register other than r0, you can override "result".) | |
| * | |
| * If "chkzero" is set to 1, we perform a divide-by-zero check on | |
| * vCC (r1). Useful for integer division and modulus. | |
| * | |
| * For: add-int/2addr, sub-int/2addr, mul-int/2addr, div-int/2addr, | |
| * rem-int/2addr, and-int/2addr, or-int/2addr, xor-int/2addr, | |
| * shl-int/2addr, shr-int/2addr, ushr-int/2addr, add-float/2addr, | |
| * sub-float/2addr, mul-float/2addr, div-float/2addr, rem-float/2addr | |
