This stops an --enable-targets selection affecting the main target in regards to forcing 64-bit archives. It also means mips64 and s390x will revert to binutils-2.25 and binutils-2.26 behaviour of not forcing 64-bit archives at least in the common case when plugins were enabled.

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.

2016-12-22Fix placement of forced local symbols in the dynamic symbol table.Cary Coutant8-97/+220

2016-12-22Class-ify ui_outSimon Marchi64-2377/+2341
This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

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.

2016-12-20Fix longjmp across readline w/ --enable-sjlj-exceptions toolchainsPedro Alves2-5/+27
Nowadays, GDB propagates C++ exceptions across readline using setjmp/longjmp 89525768cd08 ("Propagate GDB/C++ exceptions across readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding can't cross C functions compiled without -fexceptions (see details from the commit above). Unfortunately, toolchains that use SjLj-based C++ exceptions got broken with that fix, because _Unwind_SjLj_Unregister, which is put at the exit of a function, is not executed due to the longjmp added by that commit.

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.

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 Waterman13-131/+186
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.
