2017-01-20objdump: Better objdump section headers in wide modeAndrew Burgess2-8/+54
When displaying the section headers table using objdump (-h), the column containing the section header name is currently fixed at 13 characters. A section name that is longer than 13 characters will overflow the column causing the table to become miss-aligned. In this commit I change the behaviour so that _in wide mode_ (-w -h) the section name column is dynamically resized to fit the longest section name we plan to display. In wide mode the column still retains a minimum width of 13 characters. In non-wide more the behaviour is completely unchanged. While I was changing the dump_headers function I have unified the two printf lines that handled the different address widths into a single printf, the address width is now passed into printf using the '*' field width format character. binutils/ChangeLog: * objdump.c (dump_section_header): Extract max section name length from data parameter, use this when formatting output. (find_longest_section_name): New function. (dump_headers): Calculate longest section name when in wide mode, reformat to unify printing of header line. ld/ChangeLog: * testsuite/ld-elf/eh-frame-hdr.d: Update expected results.

2016-12-23MIPS16: Handle non-extensible instructions correctlyMaciej W. Rozycki4-0/+973
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.

2016-12-20MIPS16/opcodes: Respect ISA and ASE in disassemblyMaciej W. Rozycki2-1/+6
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.

2016-12-20MIPS16: Switch to 32-bit opcode table interpretationMaciej W. Rozycki2-6/+17
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'.

2016-12-20Re-work RISC-V gas flags: now we just support -mabi and -marchAndrew Waterman2-2/+25
We've decided to standardize on two flags for RISC-V: "-march" sets the target architecture (which determines which instructions can be generated), and "-mabi" sets the target ABI. We needed to rework this because the old flag set didn't support soft-float or single-float ABIs, and didn't support an x32-style ABI on RISC-V. Additionally, we've changed the behavior of the -march flag: it's now a lot stricter and only parses things we can actually understand. Additionally, it's now lowercase-only: the rationale is that while the RISC-V ISA manual specifies that ISA strings are case-insensitive, in Linux-land things are usually case-sensitive. Since this flag can be used to determine library paths, we didn't want to bake some case-insensitivity in there that would case trouble later. This patch implements these two new flags and removes the old flags that could conflict with these. There wasn't a RISC-V release before, so we want to just support a clean flag set. include/ * elf/riscv.h (EF_RISCV_SOFT_FLOAT): Don't define. (EF_RISCV_FLOAT_ABI, EF_RISCV_FLOAT_ABI_SOFT): Define.

2016-12-08MIPS16/opcodes: Fix PC-relative operation delay-slot adjustmentMaciej W. Rozycki4-0/+426
Complement commit dd8b7c222e0e ("MIPS: mips16e jalrc/jrc opcodes"), <https://sourceware.org/ml/binutils/2005-07/msg00349.html>, and stop the disassembler making a delay-slot adjustment for PC-relative operations following either MIPS16e compact jumps, or undefined RR/J(AL)R(C) encodings that have the `l' (link) and `ra' (source register is `ra') bits set both at a time. Adjust code description for accuracy. Add a suitable test case. opcodes/ * mips-dis.c (print_mips16_insn_arg): Avoid delay-slot adjustment for PC-relative operations following MIPS16e compact jumps or undefined RR/J(AL)R(C) encodings. binutils/ * testsuite/binutils-all/mips/mips16-pcrel.d: New test. * testsuite/binutils-all/mips/mips16-pcrel.s: New test source. * testsuite/binutils-all/mips/mips.exp: Run the new test.

2016-12-01Fix calculation of synthetic symbol sizes (ppc64)Luis Machado2-2/+10
The attached patch fixes a problem where nm displays bogus information for synthetic symbol sizes when --size-sort is used. This happens because the synthetic symbols (dot symbols for ppc64) are generated based on their non-dot symbols. The generation process doesn't copy over the ELF-specific bits of the regular non-dot symbols. When --size-sort is used, the code attempts to access the symbol size from the ELF-specific bits and ends up reading gargabe, causing the size to be displayed incorrectly. With the patch, i can see dot and non-dot symbols having the same size with --size-sort. This doesn't fix the fact that we don't display size information for synthetic symbols without --size-sort, which i may address in the future. binutils/ChangeLog: 2016-12-01 Luis Machado <lgustavo@codesourcery.com> * nm.c (sort_symbols_by_size): Don't read symbol size if symbol is synthetic.
