2021-04-08PR27676, PowerPC missing extended dcbt, dcbtst mnemonicsAlan Modra1-7/+82
Note that this doesn't implement the ISA to the letter regarding dcbtds (and dcbtstds), which says that the TH field may be zero. That doesn't make sense because allowing TH=0 would mean you no long have a dcbtds but rather a dcbtct instruction. I'm interpreting the ISA wording about allowing TH=0 to mean that the TH field of dcbtds is optional (in which case the TH value is 0b1000). opcodes/ PR 27676 * ppc-opc.c (DCBT_EO): Move earlier.

2019-12-18More signed overflow fixesAlan Modra1-2/+2
The arc fix in create_map avoiding signed overflow by casting an unsigned char to unsigned int before shifting, shows one of the dangers of blinding doing that. The problem in this case was that the variable storing the value, newAuxRegister->address, was a long. Using the unsigned cast meant that the 32-bit value was zero extended when long is 64 bits. Previously we had a sign extension. Net result was that comparisons in arcExtMap_auxRegName didn't match. Of course, I could have cast the 32-bit unsigned value back to signed before storing in a long, but it's neater to just use an unsigned int for the address. opcodes/ * alpha-opc.c (OP): Avoid signed overflow. * arm-dis.c (print_insn): Likewise. * mcore-dis.c (print_insn_mcore): Likewise. * pj-dis.c (get_int): Likewise. * ppc-opc.c (EBD15, EBD15BI): Likewise. * score7-dis.c (s7_print_insn): Likewise. * tic30-dis.c (print_insn_tic30): Likewise. * v850-opc.c (insert_SELID): Likewise. * vax-dis.c (print_insn_vax): Likewise. * arc-ext.c (create_map): Likewise.

2019-04-05PowerPC bc extended branch mnemonics and "y" hintsAlan Modra1-141/+141
This patch fixes a problem with disassembly of branch instructions for processors complying with PowerPC ISA versions prior to version 2.0, ie. those that use "y" bit branch taken hints. Many of the extended bcctr and bclr mnemonics that should have disassembled with a "-" suffix, ie. not taken, did not display the "-" due to the ordering in powerpc_opcodes. I believe it's been that way from the original 85dcf36d72b commit of ppc-opc.c. I've also added a BH field (optional) to a few opcodes. This gives better disassembly in raw mode, showing the branch taken hint in the mnemonic as is done for bc. It would be reasonable to add a BH field to all bcctr, bclr, and bctar extended mnemonics but that runs into a small difficulty: Currently we print all or none of the optional operands. That means for example that "bgectr cr2" would display as "bgectr cr2,0" if a BH field is added to bgectr. * ppc-opc.c (XLBH_MASK): Subtract off BH field from BB_MASK. (powerpc_opcodes): Reorder bcctr and bclr extended mnemonics to favour printing of "-" branch hint when using the "y" bit. Allow BH field on bc{ctr,lr,tar}{,l}{-,+}.

"mtfsb0 4*cr7+lt" doesn't make all that much sense, but unfortunately glibc uses just that instead of "mtfsb0 28" to clear the fpscr xe bit.

2018-11-06PowerPC instruction mask checksAlan Modra1-141/+58
The instruction mask bits should never overlap any of the operands, nor should operand bits overlap, but some operands weren't checked. This patch arranges to check the omitted operands, using a mask returned by the operand->insert function. Some tweaking of various insert functions is needed to support this: The error case must set field bits. Since I was looking at the insert functions, I tidied some dead code and simplified some of the powerpc_operands entries. gas/ * config/tc-ppc.c (insn_validate): Don't ignore mask in PPC_OPSHIFT_INV case.

2018-08-21Use operand->extract to provide defaults for optional PowerPC operandsAlan Modra1-42/+53
Most optional operands to powerpc instructions use a default value of zero, but there are a few exceptions. Those have been handled by PPC_OPERAND_OPTIONAL_VALUE and an entry in the powerpc_operands table for the default value, smuggled in the shift field. This patch changes that to using the operand extract function to provide non-zero defaults. I've also moved the code determining whether optional operands are provided or omitted, to the point the first optional operand is seen, and allowed for the possibility of optional base register operands in a future patch. The patch does change the error you get on invalid assembly like ld 3,4 You'll now see "missing operand" rather than "syntax error; end of line, expected `('". gas/ * config/tc-ppc.c (md_assemble): Delay counting of optional operands until one is encountered.

2018-07-26PowerPC Improve support for Gekko & BroadwayAlex Chadwick1-5/+71
This is a relatively straightforward patch to improve support for the IBM Gekko and IBM Broadway processors. Broadway is functionally equivalent to the IBM 750CL, while Gekko's functionality is a subset of theirs. The patch simplifies this reality and adds -mgekko and -mbroadway as aliases for -m750cl. I didn't feel it was worth wasting a PPC_OPCODE_* bit to differentiate Gekko. The patch adds a number of simplified mnemonics for special purpose register access. Notably, Broadway adds 4 additional IBAT and DBAT registers but these are not assigned sequential SPR numbers. gas/ * config/tc-ppc.c (md_show_usage): Add -mgekko and -mbroadway. * doc/as.texi (Target PowerPC options): Add -mgekko and -mbroadway. * doc/c-ppc.texi (PowerPC-Opts): Likewise. * testsuite/gas/ppc/broadway.d, * testsuite/gas/ppc/broadway.s: New test for broadway. * testsuite/gas/ppc/ppc.exp: Run new test. include/ * opcode/ppc.h (PPC_OPCODE_750): Adjust comment. opcodes/ * ppc-dis.c (ppc_opts): Add -mgekko and -mbroadway.
