2024-07-19MIPS/opcodes: Mark MT thread context move assembly idioms as aliasesMaciej W. Rozycki1-38/+38
A number of instructions in the regular MIPS opcode table are assembly idioms for the MT thread context move MFTR and MTTR instructions, so mark them as aliases accordingly. Add suitable test cases, which also cover the PAUSE assembly idiom.
2024-07-19MIPS/opcodes: Mark PAUSE as an aliasMaciej W. Rozycki1-1/+1
PAUSE is an assembly idiom for 'sll $0,$0,5', so mark it as an alias in the regular MIPS opcode table, matching the microMIPS opcode table. A test case will be supplied separately.
2024-07-19MIPS/opcodes: Reorder coprocessor moves alphabeticallyMaciej W. Rozycki1-48/+52
A number of coprocessor move encodings have been randomly sprinkled over the regular MIPS and microMIPS opcode tables rather than where they'd be expected following the alphabetic order. Fix the ordering, taking into account precedence where it has to be observed for correct disassembly. No functional change.
2024-07-19MIPS/opcodes: Make AL a shorthand for INSN2_ALIASMaciej W. Rozycki1-34/+36
Make AL a shorthand for INSN2_ALIAS with the regular MIPS and microMIPS opcode tables, just as with the MIPS16 opcode table, and use it throughout. No functional change.
2024-07-19MIPS/opcodes: Rename the AL membership shorthand to ALXMaciej W. Rozycki1-88/+88
Make room for AL as a shorthand for INSN2_ALIAS with the regular MIPS opcode table, just as with the MIPS16 opcode table. No functional change.
2024-07-19MIPS/opcodes: Remove the regular MIPS "+t" operand codeYunQiang Su1-2/+1
The semantics of the regular MIPS "+t" operand code is exactly the same as that of the "E" operand code, so replace the former with the latter in the single MFTC0 instruction with implicit 'sel' == 0 encoding where it's used, matching the encoding with explicit 'sel' as well as other instructions.
2024-07-19MIPS/opcodes: Output thread context registers numerically with MFTR/MTTRMaciej W. Rozycki1-2/+2
We print MFTR and MTTR instructions' thread context register operand in disassembly using the ABI name the register number would correspond to should the targeted register be a general-purpose register. However in most cases it is wrong, because general-purpose registers are only referred when the 'u' and 'sel' operands are 1 and 0 respectively. And even in these cases the MFGPR and MTGPR aliases take precedence over the corresponding generic instruction encodings, so you won't see the valid case to normally trigger. Conversely decoding the thread context register operand numerically is always valid, so switch to using it. Adjust test coverage accordingly.
2024-07-19MIPS/opcodes: Exclude $0 from "-x" R6 operand typeMaciej W. Rozycki1-1/+1
The "-x" operand type is used for the reverse encoding of the BOVC and BNVC instructions, where 'rs' and 'rt' have been supplied as the second and the first operand respectively rather than the order the instruction expects. In this case we require the register associated with the "-x" operand to have a higher number than the register associated with the preceding "t" operand, which precludes the use of $0. The case where 'rs' and 'rt' both refer to the same register is handled by the straight encoding of the BOVC and BNVC instructions, which come in the opcode table ahead of the corresponding reverse encoding. Therefore clear the ZERO_OK flag for the "-x" operand. No need for an extra test case as the encodings involved are already covered by "r6" and its associated GAS tests.

2023-06-15Revert "MIPS: sync oprand char usage between mips and micromips"Maciej W. Rozycki1-18/+10

2023-06-05MIPS: sync oprand char usage between mips and micromipsYunQiang Su1-10/+18
We should try our best to make mips32 using the same oprand char with micromips. So for mips32, we use: ^ is added for 5bit sa oprand for some new DSPr2 instructions: APPEND, PREPEND, PRECR_SRA[_R].PH.W the LSB bit is 11, like RD. +t is removed for coprocessor 0 destination register. 'E' does the samething. +t is now used for RX oprand for MFTR/MTTR (MT ASE) ? is added for sel oprand for MFTR/MTTR (MT ASE) For mips32, the position of sel in MFTR/MTTR is same with mfc0 etc, while for micromips, they are different. We also add an extesion format of cftc2/cttc2/mftc2/mfthc2/mttc2/mtthc2: concatenating rs with rx as the index of control or data.

2022-03-06MIPS/opcodes: Fix alias annotation for branch instructionsMaciej W. Rozycki1-5/+6
Correct issues with INSN2_ALIAS annotation for branch instructions: - regular MIPS BEQZ/L and BNEZ/L assembly instructions are idioms for BEQ/L and BNE/L respectively with the `rs' operand equal to $0, - microMIPS 32-bit BEQZ and BNEZ assembly instructions are idioms for BEQ and BNE respectively with the `rt' operand equal to $0, - regular MIPS BAL assembly instruction is an idiom for architecture levels of up to the MIPSr5 ISA and a machine instruction on its own from the MIPSr6 ISA up. Add missing annotation to BEQZ/L and BNEZ/L accordingly then and add a new entry for BAL for the MIPSr6 ISA, correcting a disassembly bug: $ mips-linux-gnu-objdump -m mips:isa64r6 -M no-aliases -d bal.o bal.o: file format elf32-tradlittlemips Disassembly of section .text: 00000000 <foo>: 0: 04110000 0x4110000 ... $ Add test cases accordingly.

2021-05-29MIPS/opcodes: Reorder legacy COP0, COP2, COP3 opcode instructionsMaciej W. Rozycki1-66/+68
Group legacy instructions using the COP0, COP2, COP3 opcodes together and by their coprocessor number, and move them towards the end of the opcode table. No functional change. With the addition of explicit ISA exclusions this is maybe not strictly necessary anymore as the individual legacy instructions are not supposed to match ISA levels or CPU implementations that have discarded them or replaced with a new instruction each, but let's not have them scattered randomly across blocks of unrelated instruction sets where someone chose to put them previously. Perhaps they could be put back in alphabetical order in the main instruction block, but let's leave it for another occasion. opcodes/ * mips-opc.c (mips_builtin_opcodes): Reorder legacy COP0, COP2, COP3 opcode instructions.
2021-05-29MIPS/opcodes: Accurately record coprocessor opcode CPU/ISA membershipMaciej W. Rozycki1-51/+51
Adjust opcode table entries for coprocessor instructions that have been removed from certain ISA levels or CPU implementations as follows: - remove CP0 memory access instructions from MIPS II up as the LWC0 and SWC0 opcodes have been reused for the LL and SC instructions respectively[1]; strictly speaking LWC0 and SWC0 have never really been defined in the first place[2], but let's keep them for now in case an odd implementation did, - remove CP0 branch instructions from MIPS IV[3] and MIPS32[4] up, as they have been removed as from those ISAs, - remove CP0 control register move instructions from MIPS32 up, as they have been removed as from that ISA[5], - remove the RFE instruction from MIPS III[6] and MIPS32[7] up, as it has been removed as from those ISAs in favour to ERET, - remove CP2 instructions from Vr5400 CPUs as their encodings have been reused for the multimedia instruction set extensions[8] and no CP2 registers exist[9], - remove CP3 memory access instructions from MIPS III up as coprocessor 3 has been removed as from that ISA[10][11] and from MIPS32 up as the LWC3 opcode has been reused for the PREF instruction and consequently all the four memory access instructions removed from the ISA (though the COP3 opcode has been retained)[12]. Update the testsuite accordingly.

Coprocessor 3 has been removed from the MIPS ISA as from MIPS III[1][2] with the LDC3 and SDC3 instructions having been replaced with LD and SD instructions respectively and therefore the doubleword move instructions from and to that coprocessor have never materialized (for 32-bit ISAs coprocessor 3 has likewise been removed as from MIPS32r2[3]).

2021-05-29MIPS/opcodes: Disassemble the RFE instructionMaciej W. Rozycki1-2/+3
Fix a commit b015e599c772 ("[MIPS] Add new virtualization instructions"), <https://sourceware.org/ml/binutils/2013-05/msg00118.html>, regression and bring the disassembly of the RFE instruction back for the relevant ISA levels. It is because the "rfe" opcode table entry was incorrectly moved behind the catch-all generic "c0" entry for CP0 instructions, causing output like: 00: 42000010 c0 0x10 to be produced rather than: 00: 42000010 rfe even for ISA levels that do include the RFE instruction. Move the "rfe" entry ahead of "c0" then, correcting the problem.

2021-05-29MIPS/opcodes: Do not use CP0 register names for control registersMaciej W. Rozycki1-12/+14
The CP0 control register set has never been defined, however encodings for the CFC0 and CTC0 instructions remained available for implementers up until the MIPS32 ISA declared them invalid and causing the Reserved Instruction exception[1]. Therefore we handle them for both assembly and disassembly, however in the latter case the names of CP0 registers from the regular set are incorrectly printed if named registers are requested. This is because we do not define separate operand classes for coprocessor regular and control registers respectively, which means the disassembler has no way to tell the two cases apart. Consequently nonsensical disassembly is produced like: cfc0 v0,c0_random Later the MIPSr5 ISA reused the encodings for XPA ASE MFHC0 and MTHC0 instructions[2] although it failed to document them in the relevant opcode table until MIPSr6 only. Correct the issue then by defining a new register class, OP_REG_CONTROL, and corresponding operand codes, `g' and `y' for the two positions in the machine instruction a control register operand can take. Adjust the test cases affected accordingly. While at it swap the regular MIPS opcode table "cfc0" and "ctc0" entries with each other so that they come in the alphabetical order.

2021-05-29MIPS/opcodes: Free up redundant `g' operand codeMaciej W. Rozycki1-4/+3
In the operand handling rewrite made for the MIPS disassembler with commit ab90248154ba ("Add structures to describe MIPS operands"), <https://sourceware.org/ml/binutils/2013-07/msg00135.html>, the `g' operand code has become redundant for the regular MIPS instruction set by duplicating the OP_REG_COPRO semantics of the `G' operand code. Later commit 351cdf24d223 ("Implement O32 FPXX, FP64 and FP64A ABI extensions") converted the CTTC1 instruction from the `g' to the `G' operand code, but still left a few instructions behind.

Correct a commit 7d64c587c15f ("Add support for the MIPS eXtended Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization ASE instructions to be wrongly always enabled with the selection of the MIPS32r2 or higher ISA. For example this source assembles successfully as shown below: $ cat xpa.s mfhc0 $2, $1 $ as -32 -mips32 -o xpa.o xpa.s xpa.s: Assembler messages: xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1' $ as -32 -mips32r2 -o xpa.o xpa.s $ objdump -d xpa.o xpa.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <.text>: 0: 40420800 mfhc0 v0,c0_random ... $ To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA instructions in the opcode table. Additionally, for XPA Virtualization ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA). Now the same source is correctly rejected unless the `-mxpa' option is also used: $ as -32 -mips32r2 -o xpa.o xpa.s xpa.s: Assembler messages: xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1' $ as -32 -mips32r2 -mxpa -o xpa.o xpa.s $ Add test cases for XPA base and XPA Virtualization ASE instructions.
