Simplify extended operand handling and only specially process immediates which require bit shuffling, using the generic operand insertion and extraction handlers for the '<' (5-bit shift amount) operand code in particular.

Bail out right away when an unextended instruction encoding is required either with the use of a `.t' suffix or by means of `.set noautoextend', however an operand supplied requires the extended instruction form to be used. This is to avoid messing up with the internal state of the assembler, even though no actual failures are known to happen as a result.

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.

2016-12-23MIPS16: Remove "extended" BREAK/SDBBP handlingMaciej W. Rozycki2-8/+6
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. According to all versions of the MIPS16 ASE specifications these instructions are not extensible [1][2][3][4][5][7][8][10][11], 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 [5][6][9][10]. 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.

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.

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'.

2016-12-20Re-work RISC-V gas flags: now we just support -mabi and -marchAndrew Waterman5-123/+122
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 Waterman3-54/+185
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).

2016-12-05[ARM] Add ARMv8.3 VCMLA and VCADD instructionsSzabolcs Nagy7-0/+281
Add support for VCMLA and VCADD advanced SIMD complex number instructions. The command line option is -march=armv8.3-a+fp16+simd for enabling all instructions.
