2017-02-24x86: also correctly support TEST opcode aliasesJan Beulich2-2/+6
Opcodes F6/1 and F7/1 are aliases of F6/0 and F7/0 in all modes. This complements commit 8b89fe14b5 ("X86: Decode opcode 0x82 as opcode 0x80 in 32-bit mode"), just that here 64-bit mode is also covered.
2017-02-23S/390: Add support for new cpu architecture - arch12.Andreas Krebbel3-79/+311
This adds support of new instructions to the S/390 specific parts. The important feature of the new instruction set is the support of single and extended precision floating point vector operations. Note: arch12 is NOT the official name of the new CPU. It just continues the series of archXX options supported as alternate names. The archXX terminology refers to the edition number of the Principle of Operations manual. The official CPU name will be added later while keeping support of the arch12 for backwards compatibility. No testsuite regressions. Committed to mainline. Bye, -Andreas- opcodes/ChangeLog: 2017-02-23 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * s390-mkopc.c (main): Accept arch12 as cpu string and vx2 as facility. * s390-opc.c: Add new operand description macros, new instruction types, instruction masks, and new .insn instruction types. * s390-opc.txt: Add new arch12 instructions. include/ChangeLog: 2017-02-23 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * opcode/s390.h (enum s390_opcode_cpu_val): New value S390_OPCODE_ARCH12.

With this change an architecture level bump due to assembly ASIs will show up as a warning/error depending on options passed to gas.

2017-02-23x86: drop stray VEX opcode 82 referencesJan Beulich2-4/+9
No such ModR/M-less opcode has ever existed in public documentation afaict, so I can't see why it had been added in the first place. Furthermore opcode 77 is special only with implied prefix 0F.
2017-02-22aarch64: actually copy first operand in convert_bfc_to_bfm()Jan Beulich2-2/+7
Commit 93562a343c ("[AArch64] PR target/20666, fix wrong encoding of new introduced BFC pseudo") changed the destination operand to 0, making the whole function invocation a no-op. We really want to copy operand 0 (a register) to operand 1 (an immediate before coming here), even if right now this likely is only a latent bug.

When I inspect the return values of disassmblers, I happen to see various -1/-2/-3 magic numbers are used in m68k-dis.c. This patch is to replace them with enum. -1 and -2 is "clearly documented" in print_ins_arg's comments, but -3 isn't. In fact, -3 is returned when FETCH_DATA returns false, which means memory error (because fetch_data return 0 on memory error). So I name enum PRINT_INSN_ARG_MEMORY_ERROR for -3.

2016-12-29Return 'int' rather than 'unsigned short' in avrdis_opcodeYao Qi2-6/+23
avrdis_opcode return type is unsigned short, but -1 at the end of this function is returned. Additionally, print_insn_avr doesn't handle when -1 (in case of memory error) is returned from avrdis_opcode. This patch changes avrdis_opcode returning int indicating the error, and adds a new argument for instruction we got on success. The opcode is 16-bit, so I change local variables type to uint16_t, and include "bfd_stdint.h" as a result. On memory error, print_insn_avr returns -1, which is a common convention among most of print_insn_$ARCH functions. opcodes: 2016-12-29 Yao Qi <yao.qi@linaro.org> * avr-dis.c: Include "bfd_stdint.h" (avrdis_opcode): Change return type to int, add argument insn.

2016-12-23MIPS16: Handle non-extensible instructions correctlyMaciej W. Rozycki3-68/+86
Identify non-extensible instructions in the MIPS16 opcode table and disallow their use with the `.e' instruction size suffix in assembly and do not interpret any EXTEND prefix present as a part of the instruction in disassembly. According to all versions of the MIPS16 ASE specifications the following instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R, I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e ASE specifications it has been further clarified what was previously implied, that non-extesiable instructions when preceded with an EXTEND prefix must cause a Reserved Instruction exception [3][5]. Therefore in the presence of an EXTEND prefix none of these instructions are supposed to be handled as extended instructions and supporting these forms in disassembly causes confusion, and in the case of the RRR major opcode it also clashes with the ASMACRO encoding.

2016-12-23MIPS16: Remove "extended" BREAK/SDBBP handlingMaciej W. Rozycki2-2/+6
Remove special casing for the `6' operand code used for the embedded trap code of the BREAK and the SDBBP instructions to support supposedly extended forms of these instructions. According to all versions of the MIPS16 ASE specifications these instructions are not extensible [1][2][3][4][5][7][8][10][11], and as from revision 2.50 of the MIPS16e ASE specifications it has been further clarified what was previously implied, that non-extesiable instructions when preceded with an EXTEND prefix must cause a Reserved Instruction exception [5][6][9][10]. Therefore supposedly extended BREAK and SDBBP instructions do not serve their purpose anymore as they do not cause a Bp and a Debug exception respectively and supporting these forms in disassembly only causes confusion.

2016-12-23MIPS16/GAS: Disallow EXTEND delay-slot schedulingMaciej W. Rozycki2-1/+6
Do not allow any explicitly coded EXTEND instruction to be automatically scheduled into a jump delay slot, as an EXTEND prefix is coupled with the next regular MIPS16 instruction and therefore swapping it with a jump would change program's semantics; EXTEND is not architecturally allowed to be present in a jump delay slot anyway. opcodes/ * mips16-opc.c (mips16_opcodes): Set NODS in `pinfo' for "extend". gas/ * testsuite/gas/mips/mips16-extend-swap.d: New test. * testsuite/gas/mips/mips16-extend-swap.s: New test source. * testsuite/gas/mips/mips.exp: Run the new test.

2016-12-20MIPS16/opcodes: Respect ISA and ASE in disassemblyMaciej W. Rozycki2-1/+11
Limit MIPS16 instruction disassembly according to the ISA level and ASE set selected, as with the regular MIPS and microMIPS instruction sets. Retain the property of `objdump -m mips:16' disassembling all MIPS16 instructions however, regardless of any ISA level recorded in the binary examined. To validate the disassembler use the GAS test suite for its convenience of running tests across multiple ISAs, even though placing the tests in the binutils test suite would be more appropriate. Adjust the single binutils test which depends on 64-bit instruction disassembly to have the ISA level required actually recorded in the binary examined. opcodes/ * mips-dis.c (mips_arch_choices): Use ISA_MIPS64 rather than ISA_MIPS3 as the `isa' selection in the `bfd_mach_mips16' entry.

2016-12-20MIPS16: Switch to 32-bit opcode table interpretationMaciej W. Rozycki3-81/+90
Switch to 32-bit MIPS16 opcode table entry interpretation, similar to how the microMIPS opcode table is handled, for both the `match' and `mask' fields, removing special casing for JAL and JALX instructions and their `a' and `i' operand codes throughout, while retaining automatic processing of extendable opcodes in assembly and disassembly. In assembly disallow size enforcement suffixes as appropriate: `.t' for both 32-bit instructions and macros and `.e' for macros only, making macro handling consistent with the microMIPS instruction set. In disassembly fully decode EXTEND prefixes prepended to unsupported instruction encodings (according to the ISA selection) rather than dumping them as hexadecimal data along with the following instruction, removing all special casing for the EXTEND prefix and making its handling rely on its opcode table entry, except where it is considered a part of an extendable instruction. include/ * opcode/mips.h (mips_opcode_32bit_p): New inline function. gas/ * config/tc-mips.c (micromips_insn_length): Use `mips_opcode_32bit_p'.

Limit the DDIV, DDIVU, DREM, DREMU and DSUBU macros to the MIPS III rather than MIPS I ISA. These macros expand to machine code sequences including 64-bit instructions which require a 64-bit ISA. Entries for those instructions are already correctly marked, however the marking is ignored if entries are used in the process of macro expansion rather than directly, making it possible to indirectly produce 64-bit machine code even when output requested has been limited to a 32-bit ISA. opcodes/ * mips16-opc.c (mips16_opcodes): Set membership to I3 rather than I1 for the "ddiv", "ddivu", "drem", "dremu" and "dsubu" INSN_MACRO entries. gas/ * testsuite/gas/mips/mips16-macro.l: New list test. * testsuite/gas/mips/mips.exp: Run the new test.
