Teach the assembler about PowerPC extended mnemonics. Also make a few changes to basic mnemonics. Fix typo in name of the basic "creqv". Add the basic "addc" and relatives, because it would be odd to have the extended "subc" without "addc". Fix the basic "rldicl", "rldicr", "rldic", "rldimi" to correctly encode the 6-bit MB field. Fix "slw" and relatives to correctly swap their RA and RS operands. Add many, but not all, of the extended mnemonics from IBM's Power ISA Version 2.06 Book I Appendix E. (I used 2.06, published 2009, just because I already had the PDF of it.) This commit includes mnemonics for branching, subtraction, traps, bit rotation, and a few others, like "mflr" and "nop". The assembler now understands branches like `beq cr7, label` and bit shifts like `slwi r7, r7, 2`. These encode the same machine instructions as the basic "bc" and "rlwinm". Some operands to basic names become optional. The assembler no longer requires the level in "sc" or the branch hint in "bcctr" and "bclr"; they default to zero. Some extended names take an optional branch hint or condition register. Some extended names are still missing. I don't provide names with static branch prediction, like "beq+" or "bge-", because the assembler parses '+' and '-' as operators, not as part of an instruction name. I also don't provide some names that 2.06 has for moving to or from the condition register or some special purpose registers, names like "mtcr" or "mfuamr". This commit also deletes some unused tokens and one unused yacc rule.

I did not try all the newly added instructions, but these seem to work: dcbt, dcbtst, icibi, isync, lwarx, stwcx., mftb, mftbu In man/powerpc_as.6 (not installed), add a summary of the registers and addressing modes (like in i386_as.6), describe short forms, update description of hi16/ha16, add CAVEATS about instructions that some processors can't run.

Swap RA and RS when assembling "and", "or", and such instructions. They must use OP_RA_RS_RB_C instead of OP_RS_RA_RB_C. The code generator often sets RS and RA to the same register, so swapping them causes no change in many programs. I also rename OP_RS_RA_UI_CC to OP_RA_RS_UI_CC, and OP_RS_RA_C to OP_RA_RS_C, because they already swap RA and RS.

Some extended names take an optional branch hint or condition register. Some extended names are still missing. I don't provide names with static branch prediction, like "beq+" or "bge-", because the assembler parses '+' and '-' as operators, not as part of an instruction name. I also don't provide some names that 2.06 has for moving to or from the condition register or some special purpose registers, names like "mtcr" or "mfuamr". This commit also deletes some unused tokens and one unused yacc rule.

Add assembler support for fixing up arbitrary oris/addi pairs of instructions; this should allow oris/lwz constant value loads, which will save an opcode.

Teach the assembler about PowerPC extended mnemonics. Also make a few changes to basic mnemonics. Fix typo in name of the basic "creqv". Add the basic "addc" and relatives, because it would be odd to have the extended "subc" without "addc". Fix the basic "rldicl", "rldicr", "rldic", "rldimi" to correctly encode the 6-bit MB field. Fix "slw" and relatives to correctly swap their RA and RS operands. Add many, but not all, of the extended mnemonics from IBM's Power ISA Version 2.06 Book I Appendix E. (I used 2.06, published 2009, just because I already had the PDF of it.) This commit includes mnemonics for branching, subtraction, traps, bit rotation, and a few others, like "mflr" and "nop". The assembler now understands branches like `beq cr7, label` and bit shifts like `slwi r7, r7, 2`. These encode the same machine instructions as the basic "bc" and "rlwinm". Some operands to basic names become optional. The assembler no longer requires the level in "sc" or the branch hint in "bcctr" and "bclr"; they default to zero. Some extended names take an optional branch hint or condition register. Some extended names are still missing. I don't provide names with static branch prediction, like "beq+" or "bge-", because the assembler parses '+' and '-' as operators, not as part of an instruction name. I also don't provide some names that 2.06 has for moving to or from the condition register or some special purpose registers, names like "mtcr" or "mfuamr".

Add instructions like "lwarx". Extend manual. Add more page numbers from PowerPC version 2.01. Remove "xnop" not in 2.01, add "mtcr" from 2.01. Add "lwarx" and the other instructions from Book II. I did not try all the newly added instructions, but these seem to work: dcbt, dcbtst, icibi, isync, lwarx, stwcx., mftb, mftbu In man/powerpc_as.6 (not installed), add a summary of the registers and addressing modes (like in i386_as.6), describe short forms, update description of hi16/ha16, add CAVEATS about instructions that some processors can't run.
