2022-10-20x86: re-work AVX-VNNI supportJan Beulich1-1/+0
By putting the templates after their AVX512 counterparts, the AVX512 flavors will be picked by default. That way the need to always use {vex} ceases to exist once respective CPU features (AVX512-VNNI or AVX512VL as a whole) have been disabled. This way the need for the PseudoVexPrefix attribute also disappears.
2022-10-18x86: Disable AVX-VNNI when disabling AVX2H.J. Lu1-1/+1
Since AVX-VNNI requires AVX2, disable AVX-VNNI when disabling AVX2. * i386-gen.c (cpu_flag_init): Add CpuAVX_VNNI to CPU_ANY_AVX2_FLAGS. * i386-init.h: Regenerate.
2022-10-18x86: correct CPU_AMX_{BF16,INT8}_FLAGSJan Beulich1-2/+2
AMX-TILE is a prereq to these, as already correctly expressed by CPU_ANY_AMX_TILE_FLAGS. Express the dependency also in the reverse ("positive") direction.
2022-09-30x86/Intel: restrict suffix derivationJan Beulich1-2/+0
While in some cases deriving an AT&T-style suffix from an Intel syntax memory operand size specifier is necessary, in many cases this is not only pointless, but has led to the introduction of various workarounds: Excessive use of IgnoreSize and NoRex64 as well as the ToDword and ToQword attributes. Suppress suffix derivation when we can clearly tell that the memory operand's size isn't going to be needed to infer the possible need for the low byte/word opcode bit or an operand size prefix (0x66 or REX.W). As a result ToDword and ToQword can be dropped entirely, plus a fair number of IgnoreSize and NoRex64 can also be got rid of. Note that IgnoreSize needs to remain on legacy encoded SIMD insns with GPR operand, to avoid emitting an operand size prefix in 16-bit mode. (Since 16-bit code using SIMD insns isn't well tested, clone an existing testcase just enough to cover a few insns which are potentially problematic but are being touched here.) Note that while folding the VCVT{,T}S{S,D}2SI templates, VCVT{,T}SH2SI isn't included there. This is to fulfill the request of not allowing L and Q suffixes there, despite the inconsistency with VCVT{,T}S{S,D}2SI.
2022-08-16x86: template-ize certain vector conversion insnsJan Beulich1-4/+26
Many of the vector conversion insns come with X/Y/Z suffixed forms, for disambiguation purposes in AT&T syntax. All of these gorups follow certain patterns. Introduce "xy" and "xyz" templates to reduce redundancy. To facilitate using a uniform name for both AVX and AVX512, further introduce a means to purge a previously defined template: A standalone <name> will be recognized to have this effect. Note that in the course of the conversion VFPCLASSPH is properly split to separate AT&T and Intel syntax forms, matching VFPCLASSP{S,D} and yielding the intended "ambiguous operand size" diagnostic in Intel mode.
2022-08-16x86: template-ize packed/scalar vector floating point insnsJan Beulich1-19/+24
The vast majority of vector FP insns comes in single/double pairs. Many pairs follow certain encoding patterns. Introduce an "sd" template to reduce redundancy. Similarly, to further cover similarities between AVX512F and AVX512-FP16, introduce an "sdh" template. For element-size Disp8 shift generalize i386-gen's broadcast size determination, allowing Disp8MemShift to be specified without an operand in the affected templated templates. While doing the adjustment also eliminate an unhelpful (lost information) diagnostic combined with a use after free in what is now get_element_size(). Note that in the course of the conversion - the AVX512F form of VMOVUPD has a stray (leftover) Load attribute dropped, - VMOVSH has a benign IgnoreSize added (the attribute is still strictly necessary for VMOVSD, and necessary for VMOVSS as long as we permit strange combinations like "-march=i286+avx"), - VFPCLASSPH is properly split to separate AT&T and Intel syntax forms, matching VFPCLASSP{S,D}.
2022-08-16revert "x86: Also pass -P to $(CPP) when processing i386-opc.tbl"Jan Beulich1-8/+27
This reverts commit 384f368958f2a5bb083660e58e5f8a010e6ad429, which broke i386-gen's emitting of diagnostics. As a replacement to address the original issue of newer gcc no longer splicing lines when dropping the line continuation backslashes, switch to using + as the line continuation character, doing the line splicing in i386-gen.
2022-07-18x86: re-order insn template fieldsJan Beulich1-2/+2
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.)
2022-07-04x86: fold Disp32S and Disp32Jan Beulich1-14/+8
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.
2022-07-04x86: restore masking of displacement kindsJan Beulich1-6/+6
Commit 7d5e4556a375 rendered the check near the end of what is now i386_finalize_displacement() entirely dead for AT&T mode, since for operands involving a displacement .unspecified will always be set. But the logic there is bogus anyway - Intel syntax operand size specifiers are of no interest there either. The only thing which matters in the "displacement only" determination is .baseindex. Of course when masking displacement kinds we should not at the same time also mask off other attributes. Furthermore the type mask returned by lex_got() also needs to be adjusted: The only case where we want Disp32 (rather than Disp32S) is when dealing with 32-bit addressing mode in 64-bit code.
2022-03-17x86: never set i386_cpu_flags' "unused" fieldJan Beulich1-4/+5
Setting this field risks cpu_flags_all_zero() mistakenly returning "false" when the object passed in was e.g. the result of ANDing together two objects which had the bit set, or ANDNing together an object with the field set and one with the field clear. While there also avoid setting CpuNo64: Like Cpu64 this is driven differently anyway and hence shouldn't be set anywhere by default. Note that the moving of the two items in i386-gen.c's cpu_flags[] is only for documentation purposes (and slight reducing of overhead), as the fields are sorted anyway upon program start.
2022-03-17x86: unify CPU flag on/off processingJan Beulich1-21/+10
There's no need for the arbitrary special "unknown" token: Simply recognize the leading ~ and process everything else the same, merely recording whether to set individual fields to 1 or 0. While there exclude CpuIAMCU from CPU_UNKNOWN_FLAGS - CPU_IAMCU_FLAGS override cpu_arch_flags anyway when -march=iamcu is passed, and there's no reason to have the stray flag set even if no insn actually is keyed to it.
2022-03-17x86: drop L1OM/K1OM support from gasJan Beulich1-7/+1
This was only rudimentary support anyway; none of the sub-architecture specific insns were ever supported.
2022-03-17x86: assorted IAMCU CPU checking fixesJan Beulich1-1/+1
The checks done by check_cpu_arch_compatible() were halfway sensible only at the time where only L1OM support was there. The purpose, however, has always been to prevent bad uses of .arch (turning off the base CPU "feature" flag) while at the same time permitting extensions to be enabled / disabled. In order to achieve this (and to prevent regressions when L1OM and K1OM support are removed) - set CpuIAMCU in CPU_IAMCU_FLAGS, - adjust the IAMCU check in the function itself (the other two similarly broken checks aren't adjusted as they're slated to be removed anyway), - avoid calling the function for extentions (which would never have the base "feature" flag set), - add a new testcase actually exercising ".arch iamcu" (which would also regress with the planned removal).
2022-01-06x86: drop NoAVX insn attributeJan Beulich1-1/+0
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.

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,Lili1-2/+8
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.

2021-03-29x86: fold SSE2AVX and their base MMX/SSE templatesJan Beulich1-1/+1
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: undo Prefix_0X<nn> use in opcode tableJan Beulich1-6/+10
The table entries are more natural to read (and slightly shorter) when the prefixes, like is the case for VEX/XOP/EVEX-encoded entries, are specified as part of the opcode. This is particularly noticable for side-by-side legacy and SSE2AVX entries. An implication is that we now need to use "unsigned long long" for the initially parsed opcode in i386-gen. I don't expect this to be an issue.
2021-03-29x86: derive opcode encoding space attribute from base opcodeJan Beulich1-5/+35
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.
2021-03-24x86: derive opcode length from opcode valueJan Beulich1-17/+15
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 Beulich1-53/+41
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 Beulich1-2/+1
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-order two fields of struct insn_templateJan Beulich1-4/+4
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 Beulich1-0/+1
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 Beulich1-4/+1
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.
2021-03-03x86: infer operand count of templatesJan Beulich1-34/+21
Having this count explicitly in the table is redundant and (even if just slightly) disturbs clarity. Infer the count from the number of operands actually found. Also convert the "no operands" indicator from "{ 0 }" to just "{}", as that (now) ends up being easier to parse.
2021-02-16x86: have preprocessor expand macrosJan Beulich1-11/+0
There's no point having i386-gen's set_bitfield() to handle any aliases, now that we pass the opcode table through the C preprocessor anyway.
