2016-12-21bfd: aarch64: fix word and arrdess size declaration in ilp32 modeYury Norov2-4/+11
ILP32 has 32-bit word and address, but currently they declared as 64-bit in bfd_aarch64_arch_ilp32, which breaks further logic of bfd. This patch fixes it. Glibc testsuite build with patched binutils shows that next tests stop to fail: iconvdata/mtrace-tst-loading iconvdata/tst-loading iconvdata/tst-tables localedata/mtrace-tst-leaks localedata/tst-leaks posix/tst-getaddrinfo4 posix/tst-getaddrinfo5 posix/tst-regex2

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.

2016-12-20MIPS16/opcodes: Respect ISA and ASE in disassemblyMaciej W. Rozycki19-2/+1698
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. Rozycki21-111/+494
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'.

2016-12-20MIPS16/opcodes: Correct 64-bit macros' ISA membershipMaciej W. Rozycki5-6/+30
Limit the DDIV, DDIVU, DREM, DREMU and DSUBU macros to the MIPS III rather than MIPS I ISA. These macros expand to machine code sequences including 64-bit instructions which require a 64-bit ISA. Entries for those instructions are already correctly marked, however the marking is ignored if entries are used in the process of macro expansion rather than directly, making it possible to indirectly produce 64-bit machine code even when output requested has been limited to a 32-bit ISA. opcodes/ * mips16-opc.c (mips16_opcodes): Set membership to I3 rather than I1 for the "ddiv", "ddivu", "drem", "dremu" and "dsubu" INSN_MACRO entries. gas/ * testsuite/gas/mips/mips16-macro.l: New list test. * testsuite/gas/mips/mips.exp: Run the new test.

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.

2016-12-20Rework RISC-V relocationsAndrew Waterman11-71/+472
Before this commit we didn't cleanly support CFI directives because the internal offsets used to get relaxed which broke them. This patch significantly reworks how we handle linker relaxations: * DWARF is now properly supported * There is a ".option norelax" to disable relaxations, for when users write assembly that can't be relaxed (if it's to be later patched up, for example). * There is an additional _RELAX relocation that specifies when previous relocations can be relaxed. We're in the process of documenting the RISC-V ELF ABI, which will include documentation of our relocations https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md but we expect that this relocation set will remain ABI compatible in the future (ie, it's safe to release).

2016-12-19MIPS/opcodes: Only call `bfd_mips_elf_get_abiflags' if BFD64Maciej W. Rozycki2-2/+14
Complement commit 5e7fc731f80e ("MIPS/opcodes: Also set disassembler's ASE flags from ELF structures") and fix an `--enable-targets=all' GDB build regression on 32-bit hosts where the MIPS target is a secondary: ../opcodes/libopcodes.a(mips-dis.o): In function `set_default_mips_dis_options': mips-dis.c:(.text+0x906): undefined reference to `bfd_mips_elf_get_abiflags' collect2: error: ld returned 1 exit status make[2]: *** [gdb] Error 1 by avoiding making a call to the `bfd_mips_elf_get_abiflags' function, which is not available, because there is no MIPS/ELF BFD included in 32-bit BFD builds. This call is only made from a conditional code block guarded by a check against `bfd_target_elf_flavour', which is dead in such a configuration, however cannot be optimized away by the compiler. Also some other MIPS BFDs may be available, such as a.out, ECOFF or PE, so the disassembler has to remain functional. opcodes/ * mips-dis.c (set_default_mips_dis_options) [BFD64]: Only call `bfd_mips_elf_get_abiflags' here.

2016-12-14MIPS/opcodes: Also set disassembler's ASE flags from ELF structuresMaciej W. Rozycki15-3/+191
Respect any ASE flags recorded in ELF file structures for the purpose of selecting instructions to be disassembled, preventing code from being hex-dumped even though having been clearly indicated as valid at the assembly time. Use date from the MIPS ABI flags structure if present, and otherwise there may be an MDMX ASE flag set in the ELF file header. For backwards compatibility only set extra flags and do not clear any, preserving all previously set by the architecture selected to be disassembled for. include/ * elf/mips.h (Elf_Internal_ABIFlags_v0): Also declare struct typedef as `elf_internal_abiflags_v0'. bfd/ * bfd-in.h (elf_internal_abiflags_v0): New struct declaration.

Move ELF file header flag interpretation code, used to set disassembler options, beyond architecture setup.
