2017-01-18PR gas/20649: MIPS: Fix GOT16/LO16 reloc pairing with comdat sectionsMaciej W. Rozycki5-5/+89
Correct a regression from commit 8614eeee67f9 ("Traditional MIPS patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>, which caused symbols in linkonce or what is these days known as comdat sections to be treated as external for the purpose of PIC relocation generation even if their binding remains STB_LOCAL. This in turn disabled GOT16/LO16 relocation pairing with references to such symbols, as no complementing LO16 relocation is expected for external GOT16 references in the o32 ABI, which ultimately leads to link errors, e.g.: ld: comdat-reloc.o: Can't find matching LO16 reloc against `foo' for R_MIPS_GOT16 at 0x24 in section `.text.bar[bar]' as with the LD test case included with this change. Revert the special case for symbols in comdat sections then, making code actually match `adjust_reloc_syms' as indicated in its explanatory comment, and adjust calling code accordingly. Also bring back the corresponding description of what now is `s_is_linkonce', lost with commit 5f0fe04bc550 ("Improved MIPS16/MIPS32 code intermixing for gas."), <https://www.sourceware.org/ml/binutils/2006-07/msg00039.html>. gas/ PR gas/20649 * config/tc-mips.c (pic_need_relax): Don't check for linkonce symbols, remove the `segtype' parameter.

2017-01-18[ARM] Fix the decoding of indexed element VCMLA instructionSzabolcs Nagy3-0/+31
Bit 24 of the indexed element vcmla decode mask was incorrectly left unset. This could cause incorrect disassembly of some currently undefined instructions as vcmla.

2016-12-23MIPS16: Handle non-extensible instructions correctlyMaciej W. Rozycki25-43/+1135
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.

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.

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.

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.
2016-12-23[msp430] Sync tc-msp430.c with devices.csvJoe Seymour2-6/+10
This patch syncs the generated data structure in tc-msp430.c with the latest version of devices.csv released by TI. My understanding is that the devices being removed were "invalid spins", so can't be being used by anyone, and never will be. Current web searches related to these devices return no relevant results. Built and tested (no regressions) as follows: Configured with: --target=msp430-elf --disable-gdb Test variations: msp430-sim/-mcpu=msp430 msp430-sim/-mcpu=msp430x msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either msp430-sim/-mhwmult=none msp430-sim/-mhwmult=f5series gas/ * config/tc-msp430.c (msp430_mcu_data): Sync with data from TI's devices.csv file as of September 2016.

2016-12-22Support aligning text section from odd addressesAndrew Waterman2-6/+21
Previously, the alignment directives were not correctly supported in the text section when current alignment was only 1 byte (i.e., when the address was odd). Since there are no 1-byte instructions in RISC-V, this patch resolves the bug by writing a zero byte to obtain 2-byte alignment, at which point a 2-byte NOP can be used to obtain 4-byte alignment.

2016-12-20MIPS16/opcodes: Respect ISA and ASE in disassemblyMaciej W. Rozycki15-0/+1681
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. Rozycki14-24/+375
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'.
