2021-04-09PowerPC disassembly of pcrel referencesAlan Modra1-10/+131
This adds some annotation to Power10 pcrel instructions, displaying the target address (ie. pc + D34 field) plus a symbol if there is one at exactly that target address. pld from the .got or .plt will also look up the entry and display it, symbolically if there is a dynamic relocation on the entry. include/ * dis-asm.h (struct disassemble_info): Add dynrelbuf and dynrelcount. binutils/ * objdump.c (struct objdump_disasm_info): Delete dynrelbuf and dynrelcount.

2019-04-05PowerPC disassembler: Don't emit trailing spacesAlan Modra1-4/+11
When an instruction has operands, the PowerPC disassembler prints spaces after the opcode so as to line up operands.

PPC_INT_FMT is redundant now that bfd.h pulls in inttypes.h if available.

2018-08-21Use operand->extract to provide defaults for optional PowerPC operandsAlan Modra1-6/+13
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. Allow for the possibility of optional base regs, ie. PPC_OPERAND_PARENS. Call ppc_optional_operand_value with extra args. include/ * opcode/ppc.h (struct powerpc_operand): Correct "insert" comment. Mention use of "extract" function to provide default value. (PPC_OPERAND_OPTIONAL_VALUE): Delete.

2018-07-26PowerPC Improve support for Gekko & BroadwayAlex Chadwick1-0/+7
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.

2018-07-02GDB PR tdep/8282: MIPS: Wire in `set disassembler-options'Maciej W. Rozycki1-6/+12
Implement MIPS target support for passing options to the disassembler, complementing commit 65b48a81404c ("GDB: Add support for the new set/show disassembler-options commands."). This includes options that expect an argument, so adjust the generic code and data structures used so as to handle such options. So as to give backends syntax flexibility no specific delimiter has been defined to separate options from their respective arguments, so it has to be included as the last character of the option name. Completion code however has not been adjusted and consequently option arguments cannot be completed at this time. Also the MIPS target has non-empty defaults for the options, so that ABI names for the general-purpose registers respect our `set mips abi ...' setting rather than always being determined from the ELF headers of the binary file selected. Handle these defaults as implicit options, never shown to the user and always prepended to the user-specified options, so that the latters can override the defaults. The resulting output for the MIPS target is as follows: (gdb) show disassembler-options The current disassembler options are '' The following disassembler options are supported for use with the 'set disassembler-options <option>[,<option>...]' command: no-aliases Use canonical instruction forms. msa Recognize MSA instructions. virt Recognize the virtualization ASE instructions. xpa Recognize the eXtended Physical Address (XPA) ASE instructions. ginv Recognize the Global INValidate (GINV) ASE instructions. gpr-names=ABI Print GPR names according to specified ABI.

The relevant part the new code is now also used by `objdump --help', which means these formatting changes apply to both outputs, except for argument list wrapping, which is GDB-specific. This also adds a separating new line between the heading and option lists where descriptions are provided, hence: (gdb) set architecture s390:31-bit (gdb) show disassembler-options The current disassembler options are '' The following disassembler options are supported for use with the 'set disassembler-options <option>[,<option>...]' command: esa Disassemble in ESA architecture mode zarch Disassemble in z/Architecture mode insnlength Print unknown instructions according to length from first two bits (gdb) but: (gdb) set architecture powerpc:common (gdb) show disassembler-options The current disassembler options are '' The following disassembler options are supported for use with the 'set disassembler-options <option>[,<option>...]' command: 403, 405, 440, 464, 476, 601, 603, 604, 620, 7400, 7410, 7450, 7455, 750cl, 821, 850, 860, a2, altivec, any, booke, booke32, cell, com, e200z4, e300, e500, e500mc, e500mc64, e5500, e6500, e500x2, efs, efs2, power4, power5, power6, power7, power8, power9, ppc, ppc32, 32, ppc64, 64, ppc64bridge, ppcps, pwr, pwr2, pwr4, pwr5, pwr5x, pwr6, pwr7, pwr8, pwr9, pwrx, raw, spe, spe2, titan, vle, vsx (gdb) Existing affected target backends have been adjusted accordingly.

2018-05-08Correct powerpc spe opcode lookupAlan Modra1-6/+6
Defining SPE2_OPCD_SEGS as 13 discounts the possibility that we'd ever look up spe2_opcd_indices[14..16], which I think is possible.

This bit is also useless as it can be replaced with PPC_OPCODE_POWER9.

Currently, the -maltivec and -mvsx GAS options enable *all* of the altivec and vsx instructions respecitively that have ever been added. This is in constract to GCC's -maltivec and -mvsx options, which only enable the oldest (ie, first) set of altivec and vsx instructions. This patch changes GAS to mimic GCC's behaviour with respect to -maltivec and -mvsx and it solves a problem with trying to assemble the lxvx instruction which is different between POWER8 and POWER9. opcodes/ * ppc-dis.c (ppc_opts) <altivec>: Do not use PPC_OPCODE_ALTIVEC2; <vsx>: Do not use PPC_OPCODE_VSX3; gas/ * testsuite/gas/ppc/altivec2.d (as): Use the -mpower8 option. (objdump): Use the -Mpower8 option.
2017-02-28GDB: Add support for the new set/show disassembler-options commands.Peter Bergner1-21/+38
This commit adds support to GDB so that it can modify the disassembler-options value that is passed to the disassembler, similar to objdump's -M option. Currently, the only supported targets are ARM, PowerPC and S/390, but adding support for a new target(s) is not difficult. include/ * dis-asm.h (disasm_options_t): New typedef.

2016-12-08Fix crash when disassembling invalid range on powerpc vleLuis Machado1-1/+1
I got a report of a gdb crash for vle and further investigation showed an attempt to disassemble an invalid memory range. I tracked the crash down to the code in get_powerpc_dialect, where we fail to make sure we have a valid section pointer before dereferencing it. There is no such problem for rs6000-based disassembling. opcodes/ChangeLog: 2016-12-08 Luis Machado <lgustavo@codesourcery.com> * ppc-dis.c (get_powerpc_dialect): Check NULL info->section.

2016-06-07PowerPC VLEAlan Modra1-34/+37
VLE is an encoding, not a particular processor architecture, so it isn't really proper to select insns based on PPC_OPCODE_VLE. For example {"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}}, {"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}}, shows two insns that have the same encoding, both available with VLE. Enabling both with VLE means we can't disassemble the second variant even if -Maltivec is given rather than -Mspe. Also, we don't check user assembly against the processor type as well as we could. Another problem is that when using the VLE encoding, insns from the main ppc opcode table are not available, except those using opcode 4 and 31. Correcting this revealed two errors in the ld testsuite, use of "nop" and "rfmci" when -mvle. This patch fixes those problems in the opcode table, and removes PPCNONE. I find a plain 0 distracts less from other values. In addition, I've implemented code to recognize some machine values from the apuinfo note present in ppc32 objects. It's not a complete disambiguation since we're lacking info to detect newer chips, but what we have should help with disassembly. include/ * elf/ppc.h (APUINFO_SECTION_NAME, APUINFO_LABEL, PPC_APUINFO_ISEL, PPC_APUINFO_PMR, PPC_APUINFO_RFMCI, PPC_APUINFO_CACHELCK, PPC_APUINFO_SPE, PPC_APUINFO_EFS, PPC_APUINFO_BRLOCK, PPC_APUINFO_VLE: Define. opcodes/ * ppc-dis.c (ppc_opts): Delete extraneous parentheses.
