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.

2016-12-23MIPS16: Handle non-extensible instructions correctlyMaciej W. Rozycki3-68/+86
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. Rozycki2-2/+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.

2016-12-23MIPS16/GAS: Disallow EXTEND delay-slot schedulingMaciej W. Rozycki2-1/+6
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.

2016-12-20MIPS16/opcodes: Respect ISA and ASE in disassemblyMaciej W. Rozycki2-1/+11
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. Rozycki3-81/+90
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'.

(match_mips16_insn): Likewise. Don't shift the instruction's opcode with the `a' and `i' operand codes. Use `mips_opcode_32bit_p' in operand decoding.

2016-12-20MIPS16/opcodes: Correct 64-bit macros' ISA membershipMaciej W. Rozycki2-6/+12
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 Waterman2-2/+11
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.

2016-12-20Formatting changes for RISC-VAndrew Waterman2-8/+10
This is a mixed bag of format changes: * Replacing constants with macros (0xffffffff with MINUS_ONE, for example). There's one technically functional change in here (some MINUS_ONEs are changed to 0), but it only changes the behavior of an otherwise-unused field. * Using 0 instead of 0x0 in the relocation table. * There were some missing spaces before parens, the spaces have been added. * A handful of comments are now more descriptive. * A bunch of whitespace-only changes, mostly alignment and brace newlines. bfd/ * elfnn-riscv.c: Formatting and comment fixes throughout. * elfxx-riscv.c: Likewise.

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.

2016-11-22gas,opcodes: fix hardware capabilities bumping in the sparc assembler.Jose E. Marchesi2-15/+50
When the assembler finds an instruction which is part of a higher opcode architecture it bumps the current opcode architecture. For example: $ echo "mwait" | as -bump {standard input}: Assembler messages: {standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait" However, when two instructions pertaining to the same opcode architecture but associated to different SPARC hardware capabilities are found in the input stream, and no GAS architecture is specified in the command line, the assembler bangs: $ echo "mwait; wr %g0,%g1,%mcdper" | as -bump {standard input}: Assembler messages: {standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait" {standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr". ... and it should'nt, as WRMCDPER pertains to the same architecture level than MWAIT. This patch fixes this by extending the definition of sparc opcode architectures to contain a set of hardware capabilities and making the assembler to take these capabilities into account when updating the set of allowed hwcaps when an architecture bump is triggered by some instruction. This way, hwcaps associated to architecture levels are maintained in opcodes, while the assembler keeps the flexibiity of defining GAS architectures including additional hwcaps (like -Asparcfmaf or the v8plus* variants). A test covering this failure case is included. gas/ChangeLog: 2016-11-22 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c: Move HWS_* and HWS2_* definitions to opcodes/sparc-opc.c.
