| // formatters in the circumstances under which they will decide to emit REX prefixes. |
| // These should be used where any register operand signifies a byte register. |
| // |
| // The disctinction is due to the handling of register numbers in the range 4..7 on |
| // x86-64. These register numbers may either represent the second byte of the first |
| // four registers (ah..bh) or the first byte of the second four registers (spl..dil). |
| // |
| // Since ah..bh cannot be used in all permutations of operands (specifically cannot |
| // be accessed where a REX prefix is present), these are likely best treated as |
| // deprecated. In order to ensure the correct registers spl..dil are selected a |
| // REX prefix will be emitted for any byte register operand in the range 4..15. |
| // |
| // These formatters may be used in instructions where a mix of operand sizes, in which |
| // case an unnecessary REX will be emitted, for example: |
| // movzbl %al, %edi |
| // In this case a REX will be planted since edi is 7 (and were this a byte operand |
| // a REX would be required to specify dil instead of bh). Unneeded REX prefixes will |
| // be silently ignored by the processor. |
| // |
| // Address operands should still be checked using regRequiresRex(), while byteRegRequiresRex() |
| // is provided to check byte register operands. |
