2021-06-10arm: avoid "shadowing" of glibc function nameJan Beulich2-16/+24
Old enough glibc has an (unguarded) declaration of index() in string.h, which triggers a "shadows a global declaration" warning.
2021-06-10arm: fix array-out-of-bounds upon register parsing errorJan Beulich2-1/+6
Despite the comment ahead of the enum explicitly pointing out the need to also update the corresponding array, 1b8833198c0 ("Add support for MVE instructions: vcmp and vpt") failed to do so. Oddly enough the issue appears to be spotted only by rather old gcc (4.3-ish in my case).
2021-06-10x86: suppress LEA optimization in a specific 16-bit caseJan Beulich5-3/+69
In 16-bit mode a 16-bit address size LEA with a 16-bit displacement and a 32-bit destination is shorter to encode than the corresponding MOV. Commit fe134c656991 ("x86: optimize LEA")'s promise was to only do the transformation when the encoding size wouldn't grow, i.e. it did go a little too far. Restrict this specific case of the transformation to -O2.
2021-06-08x86: cover a.out in recently added testsJan Beulich4-41/+47
Follow the pattern found elsewhere when relocations are involved. For wrap32-data also drop a mistakenly left "ELF" from the test name. (Note that Darwin, for which the wrap32 tests are also failing, is left as-is, for there being numerous other failures already anyway, and it hence being questionable whether that target is actually properly maintained.)
2021-06-08x86: minor improvements to optimize_imm() (part II)Jan Beulich2-3/+7
Don't kind-of-open-code fits_in_unsigned_{word,long}().
2021-06-08x86: minor improvements to optimize_disp() (part II)Jan Beulich2-7/+10
- Don't kind-of-open-code fits_in_unsigned_{word,long}(). - Fold two if()s both using fits_in_unsigned_long().
2021-06-08x86-64: avoid bogus warnings with 32-bit addressingJan Beulich9-0/+89
With optimize_disp() adjusting i.types[].bitfield.disp after adjusting the value to be used as displacement, it better also stores the updated value, to avoid subsequent "... shortened to ..." warnings. Note how optimize_imm() already does so. The -0xffffffff tests being added expose a separate issue: The encoding chosen should be 1 for ModR/M.mod, not 2. This will want to be taken care of, but not right here. This at the same time addresses a similar warning and demonstrates a similar encoding issue with 16-bit addressing. Since it was omitted when introducing the lea16-optimize test, add a plain lea16 one to also cover this.
2021-06-08x86: minor improvements to optimize_disp() (part I)Jan Beulich2-11/+18
- Do the zero checking first - there's no point in doing anything else in this case. - Drop two pointless & where just before it was checked that the respective bits are clear already anyway.
2021-06-07x86: honor quoted figure braces in i386_att_operand()Jan Beulich4-8/+43
When AVX512 support was added, symbol quotation was not paid attention to. Just like the (base,index,scale) specifier gets parsed from the end of the expression, the {...} also wants parsing from the end; in no case is the first { found a guarantee of a masking or broadcasting specifier.
2021-06-07x86: better respect quotes in parse_operands()Jan Beulich4-14/+40
When d02603dc201f ("Allow symbol and label names to be enclosed in double quotes") added the check for a double quote to the loop body there, it didn't go quite far enough: Parentheses inside quotes shouldn't be counted, and character restrictions also shouldn't apply inside quoted regions. In i386_att_operand(), which needs adjustment to remain in sync, besides respecting double quotes now, also change the logic such that we don't count parentheses anymore: Finding any opening or closing parenthesis or any double quote means we're done, because the subsequent parsing code wouldn't accept (extra) instances of these anyway. Note that in parse_operands() this mimics get_symbol_name()'s questionable behavior of treating \ specially only when ahead of ". (The behavior is suspicious because the meaning of \\ then is ambiguous. It is in particular impossible to have a (quoted) symbol name end in a single \.) I would have used get_symbol_name() here, if that didn't require fiddling with input_line_pointer.
2021-06-07x86: allow unary operators to start a memory operandJan Beulich5-14/+40
So far only - was permitted, but +, !, and ~ ought to be treated the same. Rather than adding them to digit_chars[], which was at least odd to have held - so far, drop this array and its wrapper macro for being used just once. While adjusting this logic, also include [ in the characters which may start a displacement expression - gas generally treats [] as equivalent to ().
2021-06-07x86: make symbol quotation check consistent in i386_att_operand()Jan Beulich5-7/+44
When d02603dc201f ("Allow symbol and label names to be enclosed in double quotes") added the check for a leading double quote to i386_att_operand(), it missed a second similar check after having found a segment override. To avoid the two checks going out of sync again, introduce an inline helper.
2021-06-07x86: correct absolute branch check with segment overrideJan Beulich2-9/+14
This needs to happen before checking of what may legitimately start a memory operand (like is done when there's no segment override). Plus a second '*' shouldn't be permitted when one was already found before the segment override.
2021-06-07x86/Intel: drop unnecessary bracket matching from parse_operands()Jan Beulich2-13/+8
While subsequent processing in AT&T mode relies on this simplistic early checking, Intel mode hasn't been for quite a long time (or perhaps never really did).
2021-06-07x86: remove pointless 2nd parameter from check_VecOperations()Jan Beulich3-6/+11
In the one case where non-NULL gets passed, passing NULL has the same effect. Hence the parameter is not needed at all.
2021-06-07x86: immediate operands don't allow for vector operationsJan Beulich2-10/+4
Neither masking nor broadcast are possible here, and RC/SAE get dealt with elsewhere. This also fixes gas crashes (i.e. "Fatal error: unable to continue with assembly"), since the return path being removed failed to restore input_line_pointer from save_input_line_pointer.
2021-06-07ix86: wrap constantsJan Beulich6-6/+165
Non-64-bit code should get handled the same with or without BFD64. This wasn't the case though in a number of situations (and quite likely there are more that I haven't spotted yet). It's not very nice to tie the check in md_apply_fix() to object_64bit, but afaict at that time we have no record anymore of the mode an insn was assembled in (it might also have been data). This doesn't look to be the first inconsistency of this kind, though. In x86_cons() it's even less clear what the right approach would be: flag_code shouldn't matter for data emission, but instead we'd need to know from which mode(s) the data actually gets accessed. On this basis, signed_cons() also gets adjusted.

2021-05-29MIPS/opcodes: Accurately record coprocessor opcode CPU/ISA membershipMaciej W. Rozycki3-2/+53
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.

2021-05-29MIPS/opcodes: Disassemble the RFE instructionMaciej W. Rozycki4-0/+26
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. Rozycki2-4/+11
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.

2021-05-29microMIPS/opcodes: Refer FPRs rather than FCRs with DMTC1Maciej W. Rozycki7-321/+331
The DMTC1 instruction operates on a floating-point general register as its second operand, however in the disassembly of the microMIPS encoding a floating-point control register is shown instead. This is due to an incorrect ordering of the two "dmtc1" entries in the opcode table, which gives precedence to one using the `G' aka coprocessor format over one using the `S' or floating-point register format. The coprocessor format, or OP_REG_COPRO, is used so that GAS supports referring to FPRs by their numbers in assembly, such as $0, $1, etc. however in the case of CP1/FPU it is also used by the disassembler to decode those numbers to the names of corresponding control registers. This in turn causes nonsensical disassembly such as: dmtc1 a1,c1_fir in a reference to $f0. It has been like this ever since microMIPS ISA support has been added. Correct the ordering of the two entries then by swapping them with each other, making disassembly output consistent with the regular MIPS DMTC1 instruction as well all the remaining CP1 move instructions. Adjust all the test cases affected accordingly. opcodes/ * micromips-opc.c (micromips_opcodes): Swap the two "dmtc1" entries with each other. gas/ * testsuite/gas/mips/micromips.d: Update disassembly according to "dmtc1" entry fix with opcodes. * testsuite/gas/mips/micromips-compact.d: Likewise. * testsuite/gas/mips/micromips-insn32.d: Likewise. * testsuite/gas/mips/micromips-noinsn32.d: Likewise. * testsuite/gas/mips/micromips-trap.d: Likewise. * testsuite/gas/mips/micromips@isa-override-1.d: Likewise.

2021-05-25Arm: Fix forward thumb references [PR gas/25235]Tamar Christina4-1/+72
When assembling a forward reference the symbol will be unknown and so during do_t_adr we cannot set the thumb bit. The bit it set so early to prevent relaxations that are invalid. i.e. relaxing a Thumb2 to Thumb1 insn when the symbol is Thumb. But because it's done so early we miss the case for forward references. This patch changes it so that we additionally check the thumb bit during the internal relocation processing. In principle we should be able to only set the bit during reloc processing but that would require changes to the other relocations that the instruction could be relaxed to. This approach still allows early relaxations (which means that we have less iteration of internal reloc processing) while still fixing the forward reference case. gas/ChangeLog: 2021-05-24 Tamar Christina <tamar.christina@arm.com> PR gas/25235 * config/tc-arm.c (md_convert_frag): Set LSB when Thumb symbol.

2021-05-17arm: Fix bugs with MVE vmov from two GPRs to vector lanesAlex Coplan5-3/+340
The initial problem I wanted to fix here is that GAS was rejecting MVE instructions such as: vmov q3[2], q3[0], r2, r2 with: Error: General purpose registers may not be the same -- `vmov q3[2],q3[0],r2,r2' which is incorrect; such instructions are valid. Note that for moves in the other direction, e.g.: vmov r2, r2, q3[2], q3[0] GAS is correct in rejecting this as it does not make sense to move both lanes into the same register (the Arm ARM says this is CONSTRAINED UNPREDICTABLE). After fixing this issue, I added assembly/disassembly tests for these vmovs. This revealed several disassembly issues, including incorrectly marking the moves into vector lanes as UNPREDICTABLE, and disassembling many of the vmovs as vector loads. These are now fixed. gas/ChangeLog: * config/tc-arm.c (do_mve_mov): Only reject vmov if we're moving into the same GPR twice. * testsuite/gas/arm/mve-vmov-bad-2.l: Tweak error message. * testsuite/gas/arm/mve-vmov-3.d: New test. * testsuite/gas/arm/mve-vmov-3.s: New test. opcodes/ChangeLog: * arm-dis.c (mve_opcodes): Fix disassembly of MVE_VMOV2_GP_TO_VEC_LANE when idx == 1.
