Alan Modra	9cf7e5687f	Use operand->extract to provide defaults for optional PowerPC operands 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.

Andrew Jenner	b8891f8d62	Add support for the C_SKY series of processors. This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc. This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.)

Alex Chadwick	fa758a7046	PowerPC Improve support for Gekko & Broadway 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.

Jan Beulich	2fb5be8dac	x86: drop {,reg16_}inoutportreg variables The checking against reg16_inoutportreg can be had with a simple test of a bit, and the value setting from inoutportreg can be replaced by using the actual register's reg_type field. Note that the so far redundant 2nd instance of OPERAND_TYPE_INOUTPORTREG is left in place, for its use in type_names[].	8 years ago

Maciej W. Rozycki	471b9d1507	GDB PR tdep/8282: MIPS: Wire in `set disassembler-options' Implement MIPS target support for passing options to the disassembler, complementing commit `65b48a8140` ("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.

Thomas Preud'homme	c0c468d562	[ARM] Update bfd's Tag_CPU_arch knowledge BFD's bfd_get_mach () function returns a bfd specific value representing the architecture of the target which is populated from the Tag_CPU_arch build attribute value of that target. Among other users of that interfacem, objdump which uses it to print the architecture version of the binary being examinated and to decide what instruction is available if run with "-m arm" via its own mapping from bfd_mach_arm_X values to feature bits available. However, both BFD and objdump's most recent known architecture is Armv5TE. When encountering a newer architecture bfd_get_mach will return bfd_mach_arm_unknown. This is unfortunate since objdump uses that value to allow all instructions on all architectures which is already what it does by default, making the "-m arm" trick useless. This patch updates BFD and objdump's knowledge of Arm architecture versions up to the latest Armv8-M Baseline and Mainline, Armv8-R and Armv8.4-A architectures. Since several architecture versions (eg. 8.X-A) share the same Tag_CPU_arch build attribute value and bfd_mach_arm values, the mapping from bfd machine value to feature bits need to return the most featureful feature bits that would yield the given bfd machine value otherwise some instruction would not disassemble under "-m arm" mode. The patch rework that mapping to make this clearer and simplify writing the mapping rules. In particular, for simplicity all FPU instructions are allowed in all cases. Finally, the patch also rewrite the cpu_arch_ver table in GAS to use the TAG_CPU_ARCH_X macros rather than hardcode their value. 2018-07-02 Thomas Preud'homme <thomas.preudhomme@arm.com> bfd/ * archures.c (bfd_mach_arm_5TEJ, bfd_mach_arm_6, bfd_mach_arm_6KZ, bfd_mach_arm_6T2, bfd_mach_arm_6K, bfd_mach_arm_7, bfd_mach_arm_6M, bfd_mach_arm_6SM, bfd_mach_arm_7EM, bfd_mach_arm_8, bfd_mach_arm_8R, bfd_mach_arm_8M_BASE, bfd_mach_arm_8M_MAIN): Define. * bfd-in2.h: Regenerate. * cpu-arm.c (arch_info_struct): Add entries for above new bfd_mach_arm values. * elf32-arm.c (bfd_arm_get_mach_from_attributes): Add Tag_CPU_arch to bfd_mach_arm mapping logic for pre Armv4 and Armv5TEJ and later architectures.
