2018-04-04i386: Clear vex instead of vex.evexH.J. Lu2-6/+12

Other than the variables in tc-i386.c using them, OPERAND_TYPE_REGYMM and OPERAND_TYPE_REGZMM they aren't entirely unused. No need to update i386-init.h though, as it mistakenly wasn't updated by the original commit.

2017-12-19Correct disassembly of dot product instructions.Tamar Christina5-4/+15
Dot products deviate from the normal disassembly rules for lane indexed instruction. Their canonical representation is in the form of: v0.2s, v0.8b, v0.4b[0] instead of v0.2s, v0.8b, v0.b[0] to try to denote that these instructions select 4x 1 byte elements instead of a single 1 byte element. Previously we were disassembling them following the normal rules, this patch corrects the disassembly. gas/ PR gas/22559 * config/tc-aarch64.c (vectype_to_qualifier): Support AARCH64_OPND_QLF_S_4B. * gas/testsuite/gas/aarch64/dotproduct.d: Update disassembly. include/ PR gas/22559 * aarch64.h (aarch64_opnd_qualifier): Add AARCH64_OPND_QLF_S_4B. opcodes/ PR gas/22559 * aarch64-asm.c (aarch64_ins_reglane): Change AARCH64_OPND_QLF_S_B to AARCH64_OPND_QLF_S_4B * aarch64-dis.c (aarch64_ext_reglane): Change AARCH64_OPND_QLF_S_B to AARCH64_OPND_QLF_S_4B * aarch64-opc.c (aarch64_opnd_qualifiers): Add 4b variant. * aarch64-tbl.h (QL_V2DOT): Change S_B to S_4B.
2017-12-19Add support for V_4B so we can properly reject it.Tamar Christina2-0/+6
Previously parse_vector_type_for_operand was changed to allow the use of 4b register size for indexed lane instructions. However this had the unintended side effect of also allowing 4b for normal vector registers. Because this support was only partial the rest of the tool silently treated 4b as 8b and continued. This patch adds full support for 4b so it can be properly distinguished from 8b and the correct errors are generated. With this patch you still can't encode any instruction which actually requires v<num>.4b but such instructions don't exist so to prevent needing a workaround in get_vreg_qualifier_from_value this was just omitted. gas/ PR gas/22529 * config/tc-aarch64.c (vectype_to_qualifier): Support AARCH64_OPND_QLF_V_4B. * gas/testsuite/gas/aarch64/pr22529.s: New. * gas/testsuite/gas/aarch64/pr22529.d: New. * gas/testsuite/gas/aarch64/pr22529.l: New. include/ PR gas/22529 * opcode/aarch64.h (aarch64_opnd_qualifier): Add AARCH64_OPND_QLF_V_4B. opcodes/ PR gas/22529 * aarch64-opc.c (aarch64_opnd_qualifiers): Add 4b variant.
2017-12-18x86: fold certain AVX and AVX2 templatesJan Beulich5-4106/+789
Just like for instructions in GPRs, there's no need to have separate templates for otherwise identical insns acting on XMM or YMM registers (or memory of the same size).

2017-12-18x86: replace Reg8, Reg16, Reg32, and Reg64Jan Beulich7-32766/+33250
Use a combination of a single new Reg bit and Byte, Word, Dword, or Qword instead. Besides shrinking the number of operand type bits this has the benefit of making register handling more similar to accumulator handling (a generic flag is being accompanied by a "size qualifier"). It requires, however, to split a few insn templates, as it is no longer correct to have combinations like Reg32|Reg64|Byte. This slight growth in size will hopefully be outweighed by this change paving the road for folding a presumably much larger number of templates later on.

2017-11-30x86: derive DispN from BaseIndexJan Beulich4-4142/+4196
BaseIndex implies - with the exception of string instructions the optional presence of a displacement. This is almost completely uniform for all instructions (the sole exception being MPX ones, which don't allow 16-bit addressing and hence Disp16), so there's no point in explicitly stating this in the main opcode table. Drop those explict specifications in favor of adding logic to i386-gen, shrinking the table size quite a bit and hence making it more readable. The opcodes/i386-tbl.h changes are due to a few cases where pointless Disp* still hadn't been removed from their insns.
2017-11-30x86: drop Vec_Disp8Jan Beulich6-16227/+16225
This is fully redundant with Disp8MemShift being non-zero, and hence can be folded with normal Disp8 handling.

2017-11-23x86: fix AVX-512 16-bit addressingJan Beulich2-0/+7
Despite EVEX encodings not being available in real and VM86 modes, 16-bit addressing still needs to be handled properly for 16-bit protected mode as well as 16-bit addressing in 32-bit mode. Neither should displacements be dropped silently by the assembler, nor should the disassembler fail to correctly scale 8-bit displacements.

2017-11-16x86: ignore high register select bit(s) in 32- and 16-bit modesJan Beulich2-28/+47
While commits 9889cbb14e ("Check invalid mask registers") and abfcb414b9 ("X86: Ignore REX_B bit for 32-bit XOP instructions") went a bit into the right direction, this wasn't quite enough: - VEX.vvvv has its high bit ignored - EVEX.vvvv has its high bit ignored together with EVEX.v' - the high bits of {,E}VEX.vvvv should not be prematurely zapped, to allow proper checking of them when the fields has to hold al ones - when the high bits of an immediate specify a register, bit 7 is ignored
2017-11-15x86: use correct register namesJan Beulich2-3/+8
VEX.W may be legitimately set (and is then ignored by the CPU) for non-64-bit code. Don't print 64-bit register names in such a case, by utilizing that REX_W would never be set for non-64-bit code, and that it is being set from VEX.W by generic decoding. A test for this is going to be introduced in the next patch of this series.
2017-11-15x86: drop VEXI4_Fixup()Jan Beulich2-50/+45
The low four bits of an immediate being set when the high bits specify a fourth register operand is not a problem: CPUs ignore these bits rather than raising #UD. Take care of incrementing codep in OP_EX_VexW() instead.
2017-11-15x86-64: don't allow use of %axl as accumulatorJan Beulich3-2/+7
Just like %cxl can't be used as shift count register. Otherwise for consistency %cxl would need to gain "ShiftCount" and use of both ought to properly cause REX prefixes to be emitted.

Just like is the case for xsave{s,c}64 and xrstors64 already. I wonder though why xsave{s,c} and xrstors don't allow for the q suffix, other than the other insns without the "64" suffix do.

2017-11-07ngettext supportAlan Modra2-16/+35
binutils has lacked proper pluralization of output messages for a long time, for example, readelf will display information about a section that "contains 1 entries" or "There are 1 section headers". Fixing this properly requires us to use ngettext, because other languages have different rules to English. This patch defines macros for ngettext and friends to handle builds with --disable-nls, and tidies the existing nls support. I've redefined gettext rather than just defining "_" as dgettext in bfd and opcodes in case someone wants to use gettext there (which might conceivably happen with generated code). bfd/ * sysdep.h: Formatting, comment fixes.
