2016-06-28[AArch64] Make register indices be full 64-bit valuesRichard Sandiford1-0/+5
aarch64_opnd_info used bitfields to hold vector element indices, but values were stored into those bitfields before their ranges had been checked. This meant large invalid indices could be silently truncated to smaller valid indices. The two obvious fixes were to do the range checking earlier or use a full 64-bit field for the index. I went for the latter for two reasons: - Doing the range checking in operand_general_constraint_met_p seems structurally cleaner than doing it while parsing. - The bitfields didn't really buy us anything. The imm field of the union is already 128 bits, so we can use a full int64_t index without growing the structure. The patch also adds missing range checks for the elements in a register list index. include/ * opcode/aarch64.h (aarch64_opnd_info): Change index fields to int64_t. opcodes/ * aarch64-opc.c (operand_general_constraint_met_p): Check the range of ldst_elemlist operands.

2016-06-28MIPS16: Add R_MIPS16_PC16_S1 branch relocation supportMaciej W. Rozycki1-0/+33
For R_MIPS16_PC16_S1 the calculation is `(sign_extend(A) + S - P) >> 1' and the usual MIPS16 bit shuffling applies to relocated field handling, as per the encoding of the branch target in the extended form of the MIPS16 B, BEQZ, BNEZ, BTEQZ and BTNEZ instructions. include/ * elf/mips.h (R_MIPS16_PC16_S1): New relocation. bfd/ * elf32-mips.c (elf_mips16_howto_table_rel): Add R_MIPS16_PC16_S1.

2016-06-25MIPS16/GAS: Restore unsupported relocation diagnosticsMaciej W. Rozycki1-0/+87
Correct a MIPS16 relocation handling regression in GAS introduced with: commit 177b4a6ad0047c8995fbc55016bc4f4b68d53b4a Author: Alexandre Oliva <aoliva@redhat.com> Date: Mon Mar 18 18:56:18 2002 +0000 discussed at <https://sourceware.org/ml/binutils/2002-03/msg00345.html>, which removed a preparatory call to `mips16_extended_frag' previously made from `md_estimate_size_before_relax'. As a result the function is never called with its `sec' parameter non-NULL and consequently all the unsupported relocation checks within are dead and never trigger, causing any unhandled relocations to silently resolve to 0. Unfortunately there was no sufficient test suite coverage back then to catch this. Remove all dead code then, and all the associated comments. Update the remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass the relocation section as the `sec' parameter and use it to mark frags which require an external relocation, as extended. Finally handle any outstanding MIPS16 relocations in `md_convert_frag' and report an error since we don't support any except with percent operators. gas/ * config/tc-mips.c (append_insn): Use any `O_symbol' expression unchanged with relaxed MIPS16 instructions. (mips16_extended_frag): Adjust accordingly. Return 1 right away if a relocation will be required for the symbol requested. Remove dead first relaxation pass code. (mips_relax_frag): Pass `sec' down to `mips16_extended_frag'. (md_convert_frag): Adjust symbol value calculation. Raise an error if a relocation is required for the symbol requested. * testsuite/gas/mips/mips16@relax-swap3.d: Remove dump patterns, add error output. * testsuite/gas/mips/mips16@relax-swap3.l: New error output. * testsuite/gas/mips/mips16-pcrel-relax-0.d: New test. * testsuite/gas/mips/mips16-pcrel-relax-1.d: New test. * testsuite/gas/mips/mips16-pcrel-relax-2.d: New test. * testsuite/gas/mips/mips16-pcrel-relax-3.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-0.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-1.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-2.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-3.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-4.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-5.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-6.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-7.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-0.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-1.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-2.d: New test. * testsuite/gas/mips/mips16-pcrel-addend-3.d: New test. * testsuite/gas/mips/mips16-pcrel-absolute.d: New test. * testsuite/gas/mips/mips16-branch-reloc-0.d: New test. * testsuite/gas/mips/mips16-branch-reloc-1.d: New test. * testsuite/gas/mips/mips16-branch-reloc-2.d: New test. * testsuite/gas/mips/mips16-branch-reloc-3.d: New test. * testsuite/gas/mips/mips16-branch-addend-0.d: New test. * testsuite/gas/mips/mips16-branch-addend-1.d: New test. * testsuite/gas/mips/mips16-branch-addend-2.d: New test. * testsuite/gas/mips/mips16-branch-addend-3.d: New test. * testsuite/gas/mips/mips16-branch-absolute.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-0.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-1.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-2.d: New test. * testsuite/gas/mips/mips16-absolute-reloc-3.d: New test. * testsuite/gas/mips/mips16-pcrel-reloc-2.l: New error output. * testsuite/gas/mips/mips16-pcrel-reloc-3.l: New error output. * testsuite/gas/mips/mips16-pcrel-reloc-6.l: New error output. * testsuite/gas/mips/mips16-pcrel-reloc-7.l: New error output. * testsuite/gas/mips/mips16-pcrel-addend-2.l: New error output. * testsuite/gas/mips/mips16-pcrel-addend-3.l: New error output. * testsuite/gas/mips/mips16-pcrel-absolute.l: New error output. * testsuite/gas/mips/mips16-branch-reloc-2.l: New error output. * testsuite/gas/mips/mips16-branch-reloc-3.l: New error output. * testsuite/gas/mips/mips16-branch-addend-2.l: New error output. * testsuite/gas/mips/mips16-branch-addend-3.l: New error output. * testsuite/gas/mips/mips16-branch-absolute.l: New error output. * testsuite/gas/mips/mips16-absolute-reloc-2.l: New error output. * testsuite/gas/mips/mips16-absolute-reloc-3.l: New error output. * testsuite/gas/mips/mips16-pcrel-relax-0.s: New test source. * testsuite/gas/mips/mips16-pcrel-relax-2.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-0.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-1.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-2.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-3.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-4.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-5.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-6.s: New test source. * testsuite/gas/mips/mips16-pcrel-reloc-7.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-0.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-1.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-2.s: New test source. * testsuite/gas/mips/mips16-pcrel-addend-3.s: New test source. * testsuite/gas/mips/mips16-pcrel-absolute.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-0.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-1.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-2.s: New test source. * testsuite/gas/mips/mips16-branch-reloc-3.s: New test source. * testsuite/gas/mips/mips16-branch-addend-0.s: New test source. * testsuite/gas/mips/mips16-branch-addend-1.s: New test source. * testsuite/gas/mips/mips16-branch-addend-2.s: New test source. * testsuite/gas/mips/mips16-branch-addend-3.s: New test source. * testsuite/gas/mips/mips16-branch-absolute.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-0.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-1.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-2.s: New test source. * testsuite/gas/mips/mips16-absolute-reloc-3.s: New test source. * testsuite/gas/mips/mips.exp: Run the new tests.

2016-06-23[ARC] Misc minor edits/fixesGraham Markall1-0/+7
The code supporting -mspfp, -mdpfp, and -mfpuda options are in sections of code that are commented as being for backward compatibility only, and having no effect. However, they do have an effect, enabling the SPX, DPX, and DPA instruction subclasses respectively. This commit moves the code supporting these options away from the comments indicating that they are dummy options, and also fixes a small issue where -mnps400 had the additional effect of enabling SPX instructions. A couple of other minor edits (that make no functional change) are also included. gas/ChangeLog: * config/tc-arc.c (options, md_longopts, md_parse_option): Move -mspfp, -mdpfp and -mfpuda out of the sections for dummy options. Correct erroneous enabling of SPFP instructions when using -mnps400. include/ChangeLog: * opcode/arc.h: Make insn_class_t alphabetical again. opcodes/ChangeLog: * arc-opc.c: Correct description of availability of NPS400 features.

Avoid segmentation faults in alignment checks made in `md_apply_fix' for BFD_RELOC_MIPS_18_PCREL_S3 and BFD_RELOC_MIPS_19_PCREL_S2 relocations caused by dereferencing `fixP->fx_addsy' which will be null if the relocation processed has been fully resolved. gas/ * config/tc-mips.c (md_apply_fix) <BFD_RELOC_MIPS_18_PCREL_S3> <BFD_RELOC_MIPS_19_PCREL_S2>: Avoid null pointer dereferences via `fixP->fx_addsy'.
2016-06-21MIPS/GAS: Correct BFD_RELOC_MIPS_18_PCREL_S3 calculationMaciej W. Rozycki1-0/+7
The PC-relative R_MIPS_PC18_S3 relocation and consequently its BFD internal BFD_RELOC_MIPS_18_PCREL_S3 representation is calculated from the address of the aligned doubleword containing the location being relocated: (sign_extend(A) + S - (P & ~0x7)) >> 3 rather than the address of the location itself. Reflect this in calculations made by GAS so that the relocated field is set correctly if resolved by GAS, such as with local symbols in the same section which do not require relocations to be propagated to the link stage. gas/ * config/tc-mips.c (md_pcrel_from) <BFD_RELOC_MIPS_18_PCREL_S3>: Calculate relocation from the containing aligned doubleword.

2016-06-21MIPS/GAS: Use the module level ISA setting for R6 relaxationMaciej W. Rozycki1-0/+14
Use the module level ISA setting rather than the last ISA selected with a `.set' directive in the source file in determination as to whether to keep PC-relative relocations and then with the original symbol referred, for the purpose of R6 linker relaxation. This is so that with e.g. code like this: b foo .set mips32r2 ... it's the command line options or any `.module' directive that decides how to encode any relocation for `foo' rather than the presence of `.set mips32r2'. gas/ * config/tc-mips.c (mips_force_relocation): Use `file_mips_opts' rather than `mips_opts' for the R6 ISA check.

2016-06-17opcodes,gas: adjust sparc insns and make GAS aware of itJose E. Marchesi1-0/+15
This patch marks the SPARC instructions in the opcodes table with their proper opcode architectures, and makes the assembler aware of them. This allows the assembler to properly realize when a new instruction needs a higher architecture (after v9b) and to react accordingly emitting an error message or bumping the architecture. It also expands architecture mismatch tests to cover architectures higher than v9b, and fixes a couple of minor bugs in the GAS testsuite. opcodes/ChangeLog: 2016-06-17 Jose E.

2016-06-17gas: sparc: fix collision of registers and pseudo-ops.Jose E. Marchesi1-0/+24
The current sparc assembler breaks when the name of an ancillary-state register, privileged register or hyperprivileged register has a %-pseudo-operation name as a prefix. For example, %hmcdper and %hm(), or %hintp and %hi(). This patch fixes it by introducing a new table `perc_table' (for %-table) that contains an entry for every %name supported by the assembler, other than the general registers. This table is used to detect name collisions when the assembler tries to detect a %-pseudo-op. This patch also fixes a related bug, making sure that v9a_asr_table and hpriv_reg_table are sorted in reverse lexicographic order, as otherwise the search code may fail. gas/ChangeLog: 2016-06-17 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c (priv_reg_table): Use NULL instead of the empty string to mark the end of the array. (hpriv_reg_table): Likewise. (v9a_asr_table): Likewise.

2016-06-07PowerPC VLEAlan Modra1-0/+10
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.
