2016-06-30[ARM][GAS] ARMv8.2 should enable ARMv8.1 NEON instructions.Matthew Wahab2-0/+83
GAS fails to recognize march=armv8.2-a as a superset of march=armv8.1-a when assembling NEON instructions. The patch corrects this, making -march=armv8.2-a -mfpu=neon-fp-armv8 enable the NEON intructions introduced with ARMv8.1-A. include/ 2016-06-30 Matthew Wahab <matthew.wahab@arm.com> * opcode/arm.h (ARM_ARCH_V8_2a): Add FPU_NEON_EXT_RDMA to the set of enabled FPU features. gas/ 2016-06-30 Matthew Wahab <matthew.wahab@arm.com> * testsuite/gas/arm/armv8_2+rdma.d: New.

2016-06-29GAS: Fix `abort' expansion in write.cMaciej W. Rozycki2-1/+4
Remove an internal diagnostic regression introduced with the inclusion of "libbfd.h" from write.c, added with: commit e7ff5c732e7b95aafccd0910ea1a5cb8251a1033 Author: Alan Modra <amodra@gmail.com> Date: Fri Feb 16 03:40:17 2007 +0000 That change made "libbfd.h" override the `abort' definition provided by "as.h" earlier on, making the message produced by any calls reached from write.c, which is a part of the GAS proper, look like they came from BFD, e.g.: .../gas/testsuite/gas/elf/type.s: Assembler messages: .../gas/testsuite/gas/elf/type.s:30: Error: symbol type "gnu_unique_object" is supported only by GNU targets ../as-new: BFD (GNU Binutils) 2.26.51.20160628 internal error, aborting at .../gas/write.c:608 in size_seg ../as-new: Please report this bug. vs: .../gas/testsuite/gas/elf/type.s: Assembler messages: .../gas/testsuite/gas/elf/type.s:30: Error: symbol type "gnu_unique_object" is supported only by GNU targets .../gas/testsuite/gas/elf/type.s: Internal error, aborting at .../gas/write.c:602 in size_seg Please report this bug.

2016-06-28[AArch64] Make register indices be full 64-bit valuesRichard Sandiford3-0/+77
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.

2016-06-25MIPS16/GAS: Restore unsupported relocation diagnosticsMaciej W. Rozycki77-63/+1227
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.

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.

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.

2016-06-17opcodes,gas: adjust sparc insns and make GAS aware of itJose E. Marchesi7-22/+75
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. Marchesi2-141/+264
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.
