2022-07-21x86: replace wrong attributes on VCVTDQ2PH{X,Y}Jan Beulich1-2/+2
A standalone (without SAE) StaticRounding attribute is meaningless, and indeed all other similar insns have ATTSyntax there instead. I can only assume this was some strange copy-and-paste mistake.
2022-07-21x86/Intel: correct AVX512F scatter insn element sizesJan Beulich1-4/+4
I clearly screwed up in 6ff00b5e12e7 ("x86/Intel: correct permitted operand sizes for AVX512 scatter/gather") giving all AVX512F scatter insns Dword element size. Update testcases (also their gather parts), utilizing that there previously were two identical lines each (for no apparent reason).
2022-07-18x86: correct VMOVSH attributesJan Beulich1-3/+3
Both forms were missing VexW0 (thus allowing Evex.W=1 to be encoded by suitable means, which would cause #UD). The memory operand form further was using the wrong Masking value, thus allowing zeroing-masking to be encoded for the store form (which would again cause #UD).
2022-07-18x86: re-order insn template fieldsJan Beulich1-3715/+3715
This saves quite a number of shift instructions: The "operands" field can now be retrieved by just masking (no shift), and extracting the "extension_opcode" field now only requires a (signed) right shift, with no prereq left one. (Of course there may be architectures where, in a cross build, there might be no difference at all, e.g. when there are suitable bitfield extraction insns.)
2022-07-06x86: make D attribute usable for XOP and FMA4 insnsJan Beulich1-656/+34
This once again allows to reduce redundancy in (and size of) the opcode table. Don't go as far as also making D work on the two 5-operand XOP insns: This would significantly complicate the code, as there the first (immediate) operand would need special treatment in several places. Note that the .s suffix isn't being enabled to have any effect, for being deprecated. Whereas neither {load} nor {store} pseudo prefixes make sense here, as the respective operands are inputs (loads) only anyway, regardless of order. Hence there is (as before) no way for the programmer to request the alternative encoding to be used for register- only insns. Note further that it is always the first original template which is retained (and altered), to make sure the same encoding as before is used for register-only insns. This has the slightly odd (but pre- existing) effect of XOP register-only insns having XOP.W clear, but FMA4 ones having VEX.W set.
2022-07-04x86: fold Disp32S and Disp32Jan Beulich1-12785/+12800
The only case where 64-bit code uses non-sign-extended (can also be considered zero-extended) displacements is when an address size override is in place for a memory operand (i.e. particularly excluding displacements of direct branches, which - if at all - are controlled by operand size, and then are still sign-extended, just from 16 bits). Hence the distinction in templates is unnecessary, allowing code to be simplified in a number of places. The only place where logic becomes more complicated is when signed-ness of relocations is determined in output_disp(). The other caveat is that Disp64 cannot be specified anymore in an insn template at the same time as Disp32. Unlike for non-64-bit mode, templates don't specify displacements for both possible addressing modes; the necessary adjustment to the expected ones has already been done in match_template() anyway (but of course the logic there needs tweaking now). Hence the single template so far doing so is split.
2022-06-29x86: drop stray NoRex64 from XBEGINJan Beulich1-1/+1
Presumably this being there was a result of taking CALL as a reference when adding the RTM insns. But with No_qSuf the attribute has no effect.
2022-05-27x86: re-work AVX512 embedded rounding / SAEJan Beulich1-10941/+591
As a preparatory step to allowing proper non-operand forms of specifying embedded rounding / SAE, convert the internal representation to non- operand form. While retaining properties (and in a few cases perhaps providing more meaningful diagnostics), this means doing away with a few hundred standalone templates, thus - as a nice side effect - reducing memory consumption / cache occupancy.
2022-04-27x86: VFPCLASSSH is Evex.LLIGJan Beulich1-1/+1
This also was mistakenly flagged as Evex.128.
2022-04-19x86: VCMPSH is Evex.LLIGJan Beulich1-94/+94
These were mistakenly flagged as Evex.128. Getting the LLIG status right for insns allowing for SAE is a prereq for planned further work.
2022-04-19x86: drop stray CheckRegSize from VFPCLASSPHJan Beulich1-1/+1
Like VFPCLASSP{S,D} it has only a single operand allowing multiple sizes, hence there are no pairs of operands to check for consistent size.
2022-03-18x86: also fold remaining multi-vector-size shift insnsJan Beulich1-339/+50
By slightly relaxing the checking in operand_type_register_match() we can fold the vector shift insns with an XMM source as well. While strictly speaking an overlap in just one size (see the code comment) is not enough (both operands could have multiple sizes with just a single common one), this is good enough for all templates we have, or which could sensibly / usefully appear (within the scope of the present operand matching model). Tightening this a little would be possible, but would require broadcast related information to be passed into the function.
2022-03-18x86: drop stray CheckRegSize from VEXTRACT{F,I}32X4Jan Beulich1-2/+2
They have only a single operand allowing multiple sizes, hence there are no pairs of operands to check for consistent size.
2022-03-18x86: fold certain AVX2 templates into their AVX counterpartsJan Beulich1-2092/+462
Like for AVX512VL we can make the handling of operand sizes a little more flexible to allow reducing the number of templates we have.
2022-03-17x86: drop L1OM/K1OM support from gasJan Beulich1-5440/+5440
This was only rudimentary support anyway; none of the sub-architecture specific insns were ever supported.
2022-01-06x86: drop NoAVX insn attributeJan Beulich1-4472/+4472
To avoid issues like that addressed by 6e3e5c9e4181 ("x86: extend SSE check to PCLMULQDQ, AES, and GFNI insns"), base the check on opcode attributes and operand types.
2022-01-06x86: drop NoAVX from POPCNTJan Beulich1-1/+1
With the introduction of CpuPOPCNT the NoAVX attribute has become meaningless for POPCNT.
2022-01-06x86: drop some "comm" template parametersJan Beulich1-48/+48
As already indicated in a remark when introducing these templates, the "commutative" attribute is ignored for legacy encoding templates. Hence it is possible to shorten a number of templates by specifying C directly rather than through a template parameter. I think this helps readability a bit.
2022-01-06x86: templatize FMA insn templatesJan Beulich1-747/+747
The operand ordering portion of the mnemonics repeats, causing a flurry of almost identical templates. Abstract this out.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.
2021-08-05[PATCH 1/2] Enable Intel AVX512_FP16 instructionsCui,Lili1-15911/+23504
Intel AVX512 FP16 instructions use maps 3, 5 and 6. Maps 5 and 6 use 3 bits in the EVEX.mmm field (0b101, 0b110). Map 5 is for instructions that were FP32 in map 1 (0Fxx). Map 6 is for instructions that were FP32 in map 2 (0F38xx). There are some exceptions to this rule. Some things in map 1 (0Fxx) with imm8 operands predated our current conventions; those instructions moved to map 3. FP32 things in map 3 (0F3Axx) found new opcodes in map3 for FP16 because map3 is very sparsely populated. Most of the FP16 instructions share opcodes and prefix (EVEX.pp) bits with the related FP32 operations. Intel AVX512 FP16 instructions has new displacements scaling rules, please refer to the public software developer manual for detail information. gas/ 2021-08-05 Igor Tsimbalist <igor.v.tsimbalist@intel.com> H.J.

2021-04-26x86: optimize LEAJan Beulich1-1/+1
Over the years I've seen a number of instances where people used lea (%reg1), %reg2 or lea symbol, %reg despite the same thing being expressable via MOV. Since additionally LEA often has restrictions towards the ports it can be issued to, while MOV typically gets dealt with simply by register renaming, transform to MOV when possible (without growing opcode size and without altering involved relocation types). Note that for Mach-O the new 64-bit testcases would fail (for BFD_RELOC_X86_64_32S not having a representation), and hence get skipped there.
2021-03-30x86: adjust st(<N>) parsingJan Beulich1-5/+1
st(1) ... st(7) will never be looked up in the hash table, so there's no point inserting the entries. It's also not really necessary to do a 2nd hash lookup after parsing the register number, nor is there a real reason for having both st and st(0) entries. Plus we can easily do away with the need for st to be first in the table.
2021-03-29x86: move some opcode table entriesJan Beulich1-459/+459
For a long time there hasn't been a need anymore to keep together all templates with identical mnemonics. Move the MOVQ and MOVABS ones next to their MOV counterparts. Move the string forms of CMPSD and MOVSD next to their CMPS / MOVS counterparts. Re-arrange what so fgar was the SSE3 section. This makes reasonably obvious that MONITOR/MWAIT aren't suitable to cover by CpuSSE3, but adjusting this is left for another time.
2021-03-29x86: VPSADBW's source operands are also commutativeJan Beulich1-3/+3
In commit 79dec6b7baa2 ("x86-64: optimize certain commutative VEX-encoded insns") I missed the fact that there being subtraction involved here doesn't matter, as absolute differences get summed up.
2021-03-29x86: fold SSE2AVX and their base MMX/SSE templatesJan Beulich1-356/+356
This way not only the overall (source) table size shrinks by quite a bit and the risk of related templates going out of sync with one another gets lowered, but also (dis)similarities between neighboring templates become easier to spot. Note that for certain SSE2AVX templates this results in benign attribute changes: - LDMXCSR and STMXCSR: NoAVX gets set, - MOVMSKPS, PMOVMSKB, PEXTR{B,W} (register destination), and PINSR{B,W} (register source): IgnoreSize and NoRex64 get set, - CVT{DQ,PS}2PD, CVTSD2SS, MOVMSKPD, MOVDDUP, PMOV{S,Z}X{BW,WD,DQ}, and ROUNDSD: NoRex64 gets set, - CVTSS2SD, INSERTPS, PEXTRW (memory destination), PINSRW (memory source), and PMOV{S,Z}X{BD,WQ,BQ}: IgnoreSize gets set. Similarly the "normal" (non-SSE2AVX) - non-64-bit CVTS{I,S}2SD forms get NoRex64 set, - CMP{EQ,ORD,NEQ,UNORD}{P,S}{S,D} forms get C set, all again in a benign way. The remaining differences in the generated table are due to re-ordering of entries in the course of being folded into templates.
2021-03-29x86: derive opcode encoding space attribute from base opcodeJan Beulich1-1596/+1596
Just like is already done for VEX/XOP/EVEX encoded insns, record the encoding space information in the respective opcode modifier field. Do this again without changing the source table, but rather by deriving the values from their existing source representation.
2021-03-26x86-64: don't accept supposedly disabled MOVQ formsJan Beulich1-2/+2
While all of MMX, SSE, and SSE2 are included in "generic64", they can be individually disabled. There are two MOVQ forms lacking respective attributes. While the MMX one would get refused anyway (due to MMX registers not recognized with .nommx), the assembler did happily accept the SSE2 form. Add respective CPU settings to both, paralleling what the MOVD counterparts have.
2021-03-25x86: fix AMD Zen3 insnsJan Beulich1-1/+52
For INVLPGB the operand count was wrong (besides %edx there's also %ecx which is an input to the insn). In this case I see little sense in retaining the bogus 2-operand template. Plus swapping of the operands wasn't properly suppressed for Intel syntax. For PVALIDATE, RMPADJUST, and RMPUPDATE bogus single operand templates were specified. These get retained, as the address operand is the only one really needed to expressed non-default address size, but only for compatibility reasons. Proper multi-operand insn get introduced and the testcases get adjusted / extended accordingly. While at it also drop the redundant definition of __amd64__ - we already have x86_64 defined (or not) to distinguish 64-bit and non-64-bit cases.
2021-03-24x86: derive opcode length from opcode valueJan Beulich1-4034/+4034
In the majority of cases we can easily determine the length from the encoding, irrespective of whether a prefix is specified there as well. We further don't even need to record the value in the table entries, as it's easy enough to determine it (without any guesswork, unless an insn with major opcode 00 appeared that requires a 2nd opcode byte to be specified explicitly) when installing the chosen template for further processing. Should an encoding appear which - has a major opcode byte of 66, F3, or F2, - requires a 2nd opcode byte to be specified explicitly, - doesn't have a mandatory prefix we'd need to convert all templates presently encoding a mandatory prefix this way to the Prefix_0X<nn> model to eliminate the respective guessing i386-gen does.
2021-03-24x86: derive mandatory prefix attribute from base opcodeJan Beulich1-4974/+4974
Just like is already done for legacy encoded insns, record the mandatory prefix information in the respective opcode modifier field. Do this without changing the source table, but rather by deriving the values from their existing source representation.
2021-03-24x86: don't use opcode_length to identify pseudo prefixesJan Beulich1-11/+11
This is in preparation of opcode_length going away as a field in the templates. Identify pseudo prefixes by a base opcode of zero instead: No real prefix has an opcode of zero. This at the same time allows dropping a curious special case from i386-gen. Since most attributes are identical for all pseudo prefixes, take the opportunity and also template them.
2021-03-23x86: re-number PREFIX_0X<nn>Jan Beulich1-148/+148
In preparation to use PREFIX_0X<nn> attributes also in VEX/XOP/EVEX encoding templates, renumber the pseudo-enumerators such that their values can then also be used directly in the respective prefix bit fields.
2021-03-23x86: re-order two fields of struct insn_templateJan Beulich1-12099/+12099
To facilitate a subsequent table parser change, re-order CPU flags and opcode modifier fields. No functional change intended.
2021-03-23x86: split opcode prefix and opcode space representationJan Beulich1-7156/+7156
Commit 8b65b8953af2 ("x86: Remove the prefix byte from non-VEX/EVEX base_opcode") used the opcodeprefix field for two distinct purposes. In preparation of having VEX/XOP/EVEX and non-VEX templates become similar in the representatioon of both encoding space and opcode prefixes, split the field to have a separate one holding an insn's opcode space.
2021-03-09x86: fold some prefix related attributes into a single oneJan Beulich1-7438/+7438
RepPrefixOk, HLEPrefixOk, and NoTrackPrefixOk can't be specified together, so can share an enum-like field. IsLockable can be inferred from HLE setting and hence only needs specifying when neither of them is present.
2021-03-09x86-64: make SYSEXIT handling similar to SYSRET'sJan Beulich1-1/+1
Despite SYSEXIT being an Intel-only insn in long mode, its behavior there is similar to SYSRET's: Depending on REX.W execution continues in either 64-bit or compatibility mode. Hence distinguishing by suffix is as necessary here as it is there.
2021-02-16x86: CVTPI2PD has special behaviorJan Beulich1-1/+31
CVTPI2PD with a memory operand, unlike CVTPI2PS, doesn't engage MMX logic. Therefore it - has a proper AVX equivalent (CVTDQ2PD) and hence can be subject to SSE2AVX translation and SSE checking, - should not record MMX use in the respective ELF note.
