2019-10-07x86/Intel: correct MOVSD and CMPSD handlingJan Beulich3-12/+18
First and foremost the EsSeg attribute was misplaced for CMPSD. Then both it and MOVSD were lacking Dword on both of their operands. Finally string insns with multiple operands and requiring use of ES: had the wrong operand number reported in the diagnostic.

2019-09-20x86-64: fix handling of PUSH/POP of segment registerJan Beulich3-4/+39
Commit 21df382b91 ("x86: fold SReg{2,3}") went too far: Folding 64-bit PUSH/POP templates into non-64-bit ones isn't correct, due to the different operand widths, and hence suffixes permitted. Restore the separate templates. Add tests of PUSH/POP with q suffix and %fs/%gs operands to the testsuite. While doing so also add PUSHF/POPF ones _without_ suffix.
2019-09-19bfd_section_* macrosAlan Modra2-1/+5
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2019-09-18Re-generate many configure and Makefile.in filesSimon Marchi3-16/+8
I get some spurious changes when running autoconf/automake for various projects in the tree. This is likely because they were generated using distro-patched tools last time.

2019-07-22This patch addresses the change in the June Armv8.1-M Mainline ↵Barnaby Wilks1-4/+0
specification, that marks certain MVE instructions as no longer UNPREDICTABLE when a source operand is the same as a destination operand for a 32-bit element size.

2019-07-19cpu,opcodes,gas: use %r0 and %r6 instead of %a and %ctf in eBPF disassemblerJose E. Marchesi2-4/+8
This patch changes the eBPF CPU description to prefer the register names %r0 and %r6 instead of %a and %ctx when disassembling. This matches better with the current practice, vs. cBPF. It also updates the GAS tests in order to reflect this change. Tested in a x86_64 host. cpu/ChangeLog: 2019-07-19 Jose E.

2019-07-17x86: drop stale Mem enumeratorJan Beulich3-4/+24
This was supposed to also be removed by c48dadc9a8 ('x86: drop "mem" operand type attribute'). It's odd enough that this hasn't caused build issues, considering the careful use of OTunused (apparently to avoid "missing initializer" warnings). To avoid such happening again introduce compile time consistency checks.
2019-07-16x86: make RegMem an opcode modifierJan Beulich6-16487/+20423
... instead of an operand type bit: It's an insn property, not an operand one. There's just one actual change to be made to the templates: Most are now required to have the (unswapped) destination go into ModR/M.rm, so VMOVD template needs its opcode adjusted accordingly and its operands swapped. {,V}MOVS{S,D}, otoh, are left alone in this regard, as otherwise generated code would differ from what we've been producing so far (which I don't think is wanted). Take the opportunity and add a missing IgnoreSize to pextrb (leading to an error in 16-bit mode), and take the liberty to once again drop stray IgnoreSize attributes from lines changed and neighboring related ones.
2019-07-16x86: fold SReg{2,3}Jan Beulich7-23935/+13937
They're the only exception to there generally being no mix of register kinds possible in an insn operand template, and there being two bits per operand for their representation is also quite wasteful, considering the low number of uses. Fold both bits and deal with the little bit of fallout. Also take the liberty and drop dead code trying to set REX_B: No segment register has RegRex set on it. Additionally I was quite surprised that PUSH/POP with the permitted segment registers is not covered by the test cases. Add the missing pieces.

The eBPF non-generic load instructions ldind{b,h,w,dw} and ldabs{b,h,w,dw} do not take an explicit destination register as an argument. Instead, they put the loaded value in %r0, implicitly. This patch fixes the CPU BPF description to not expect a 'dst' argument in these arguments, regenerates the corresponding files in opcodes, and updates the impacted GAS tests.

Older gcc warns, arguably incorrectly, about name collisions between global functions and function-local variable names.

2019-07-02[AArch64] Add missing C_MAX_ELEM flags for SVE conversionsRichard Sandiford2-28/+33
SVE FCVTZS, FCVTZU, SCVTF and UCVTF need the same treatment as FCVT: the register size used in a predicated MOVPRFX must be the wider of the destination and source sizes. Since I was adding a (supposedly) complete set of tests for converts, it seemed more consistent to add a complete set of tests for shifts as well, even though there's no bug to fix there. 2019-07-02 Richard Sandiford <richard.sandiford@arm.com> opcodes/ * aarch64-tbl.h (aarch64_opcode_table): Add C_MAX_ELEM flags to SVE fcvtzs, fcvtzu, scvtf and ucvtf entries. gas/ * testsuite/gas/aarch64/sve-movprfx_26.s: Also test FCVTZS, FCVTZU, SCVTF, UCVTF, LSR and ASR. * testsuite/gas/aarch64/sve-movprfx_26.d: Update accordingly. * testsuite/gas/aarch64/sve-movprfx_26.l: Likewise.

2019-07-01[gas][aarch64][SVE2] Fix pmull{t,b} requirement on SVE2-AESMatthew Malcomson5-301/+340
I had mistakenly given all variants of the new SVE2 instructions pmull{t,b} a dependency on the feature +sve2-aes. Only the variant specifying .Q -> .D sizes should have that restriction. This patch fixes that mistake and updates the testsuite to have extra tests (matching the given set of tests per line in aarch64-tbl.h that the rest of the SVE2 tests follow). We also add a line in the documentation of the command line to clarify how to enable `pmull{t,b}` of this larger size. This is needed because all other instructions gated under the `sve2-aes` architecture extension are marked in the instruction documentation by an `HaveSVE2AES` check while pmull{t,b} is gated under the `HaveSVE2PMULL128` check.

2019-07-01x86: drop Vec_Imm4Jan Beulich6-9985/+9983
It is pretty wasteful to have a per-operand flag which is used in exactly 4 cases. It can be relatively easily replaced, and by doing so I've actually found some dead code to remove at the same time (there's no case of ImmExt set at the same time as Vec_Imm4).
2019-07-01x86: limit ImmExt abuseJan Beulich3-126/+136
In quite a few cases ImmExt gets used when there's not really any immediate, but rather a degenerate ModR/M byte. ENCL{S,U} show how this case is supposed to be dealt with. Eliminate most abuses, leaving in place (for now) only ones where process_immext() is involved.
2019-07-01x86: optimize AND/OR with twice the same registerJan Beulich3-4/+10
It seems to be not uncommon for people to use AND or OR in this form for just setting the status flags. TEST, which doesn't write to any register other than EFLAGS, ought to be preferred. Make the change only for -O2 and above though, at least for now.
2019-07-01x86-64: optimize certain commutative VEX-encoded insnsJan Beulich3-334/+371
When they're in the 0F opcode space, swapping their source operands may allow switching from 3-byte to 2-byte VEX prefix encoding. Note that NaN behavior precludes us doing so for many packed and scalar floating point insns; such an optimization would need to be done by the compiler instead in this case, when it knows that NaN-s have undefined behavior anyway. While for explicitly specified AVX/AVX2 insns the optimization (for now at least) gets done only for -O2 and -Os, it is utilized by default in SSE2AVX mode, as there we're re-writing the programmer's specified insns anyway. Rather than introducing a new attribute flag, the change re-uses one which so far was meaningful only for EVEX-encoded insns.
2019-07-01x86: optimize EVEX packed integer logical instructionsJan Beulich3-8/+14
As long as there's no write mask as well as no broadcast, and as long as the scaled Disp8 wouldn't result in a shorter EVEX encoding, encode VPAND{D,Q}, VPANDN{D,Q}, VPOR{D,Q}, and VPXOR{D,Q} acting on only the lower 16 XMM/YMM registers using their VEX equivalents with -O1. Also take the opportunity and avoid looping twice over all operands when dealing with memory-with-displacement ones.
2019-07-01x86: add missing pseudo ops for VPCLMULQDQ ISA extensionJan Beulich4-1/+168
While the ISA extensions doc suggests them to be made available just like the SDM does for the PCLMULQDQ ISA extension, these weren't added when supposrt for the new extension was introduced. Also make sure the 64-bit non-AVX512 test actually tests VEX encodings, not EVEX ones.
2019-07-01x86: drop bogus Disp8MemShift attributesJan Beulich3-6/+12
In commit dc821c5f9a ("x86: replace Reg8, Reg16, Reg32, and Reg64") I apparently blindly copied the original register/memory templates into separate ones, in particular without removing the Disp8MemShift which are applicable to templates with memory operands only.

2019-06-27x86: allow VEX et al encodings in 16-bit (protected) modeJan Beulich2-33/+42
These encodings aren't valid in real and VM86 modes, but they are very well usable in 16-bit protected mode. A few adjustments in the disassembler tables are needed where Ev or Gv were wrongly used. Additionally an adjustment is needed to avoid printing "addr32" when that's already recognizable by the use of %eiz. Furthermore the Iq operand template was wrong for XOP:0Ah encoding insns: They're having a uniform 32-bit immediate. Drop Iq and introduce Id instead. Clone a few existing test cases to exercise assembler and disassembler.
