APPENDIX A Support for Extended Mnemonics The IBM440GP defines two sets of instruction codes defined in Section 28 5 of the IBM PPC440GP Embedded Processor User s Manual Preliminary The Book E opcodes are the ones that are displayed by default in the disassembly listing The IBM440GP disassembler also supports the Extended Mnemonics for the PowerPC family as listed in Section 28 5 subject to the qualifications detailed in this appendix The actual opcode binary between the two mnemonics is unchanged simply the mnemonic text that is used to represent the opcode Because there is no way for the IBM440GP software to know which opcodes the user prefers to view a select field has been added to allow switching from one to the other Refer to Section 6 1 for information on how this switching is done The following Extended Mnemonics documented in Section 28 5 are supported Table 28 4 Extended Mnemonics for addi la addi RT RA D li addi RT 0 IM subi addi RT RA IM Table 28 5 Extended Mnemonics for addic subic addic RT RA M Table 28 6 Extended Mnemonics for addic subic addic RT RA M Table 28 7 Extended Mnemonics for addis lis subis addis RT 0 IM addis RT RA IM Table 28 8 Extended Mnemonics for bc bca bcl bcla NOTE where duplicate extended mnemonics exist they are shown in a merged form For example bge nl bdnz be 16 0 target bdnza bca 16 0 target bdnzl bcl 16 0 target bdnzla bcla 16 0 tar
