Instructions with the same op code, mnemonic, and function

Edit online

The instructions are available in POWER® family and PowerPC®. These instructions share the same op code and mnemonic, and have the same function in a POWER® family and PowerPC®.

The following instructions are available in POWER® family and PowerPC®. These instructions share the same op code and mnemonic, and have the same function in POWER® family and PowerPC®, but use different input operand formats.

  • cmp
  • cmpi
  • cmpli
  • cmpl

The input operand format for POWER® family is:

BF, RA, SI | RB | UI

The input operand format for PowerPC® is:

BF, L, RA, SI | RB | UI

The assembler handles these as the same instructions in POWER® family and PowerPC®, but with different input operand formats. The L operand is one bit. For POWER® family, the assembler presets this bit to 0. For 32-bit PowerPC® platforms, this bit must be set to 0, or an invalid instruction form results.
