* x86: parse VEX and alike specifiers for .insnJan Beulich2023-03-311-0/+2
| | | | | | | | | | All encoding spaces can be used this way; there's a certain risk that the bits presently reserved could be used for other purposes down the road, but people using .insn are expected to know what they're doing anyway. Plus this way there's at least _some_ way to have those bits set. For now this will only allow operand-less insns to be encoded this way.
* x86: VexVVVV is now merely a booleanJan Beulich2023-03-201-17/+2
| | | | | | | | | | With the SDM long having dropped the NDS/NDD/DDS concept of identifying encoding variants, we can finally do away with this concept as well. Of the few consumers of the attribute, only an assertion was still checking for a particular value, which we don't really need to retain. When touching lines anyway, modernize other aspects as well. This often improves similarity to adjacent lines.
* x86: MONITOR/MWAIT are not SSE3 insnsJan Beulich2023-02-241-0/+3
| | | | | These have their own CPUID bit and hence they should also have their own separate control.
* x86-64: don't permit LAHF/SAHF with "generic64"Jan Beulich2023-02-241-0/+3
| | | | | | | | The feature isn't universally available on 64-bit CPUs. Note that in i386-gen.c:isa_dependencies[] I'm only adding it to models where I'm certain the functionality exists. For Nocona and Core I'm uncertain in particular.
* x86: drop use of VEX3SOURCESJan Beulich2023-02-101-7/+0
| | | | | | | | | | | | The attribute really specifies that the sum of register and memory operands is 4. Express it like that in most places, while using the 2nd (apart from XOP) CPU feature flags (FMA4) in reversed operand matching logic. With the use in build_modrm_byte() gone, part of an assertion there also becomes meaningless - simplify that at the same time. With all uses of the opcode modifier field gone, also drop that.
* x86: drop use of XOP2SOURCESJan Beulich2023-02-101-2/+0
| | | | | | | | | | The few XOP insns which used it wrongly didn't have VexVVVV specified. With that added, the only further missing piece to use more generic code elsewhere is SwapSources - see e.g. the BMI2 insns for similar operand patterns. With the only users gone, drop the #define as well as the special case code.
* x86: move (and rename) opcodespace attributeJan Beulich2023-02-101-25/+23
| | | | | | | | | | | | This really isn't a "modifier" and rather ought to live next to the base opcode anyway. Use the bits we presently have available to fit in the field, renaming it to opcode_space. As an intended side effect this helps readability at the use sites, by shortening the references quite a bit. In generated code arrange for human readable output, by using the SPACE_* constants there rather than raw numbers. This may aid debugging down the road.
* x86: use ModR/M for FPU insns with operandsJan Beulich2023-01-271-2/+2
| | | | | This is the correct way of expressing things; encoding the ModR/M byte directly in base_opcode has always been bogus.
* x86: embed register names in reg_entryJan Beulich2023-01-201-1/+1
| | | | | | | | | | Register names are (including their nul terminators) on average almost 4 bytes long. Otoh no register name is longer than 7 bytes. Hence even for 32-bit builds using a pointer is only slightly more space efficient than embedding the strings. A level of indirection can be also avoided by embedding the names as an array of 8 characters directly in the struct, and the number of base relocations in PIE builds of gas goes down as well.
* x86: move insn mnemonics to a separate tableJan Beulich2023-01-201-1/+1
| | | | | | | | | | | | | | Using full pointers to reference the insn mnemonic strings is not very efficient. With overall string size presently just slightly over 20k, even a 16-bit value would suffice. Use "unsigned int" for now, as there's no good use we could presently make of the otherwise saved 16 bits. For 64-bit builds this reduces table size by 6.25% (prior to the recent ISA extension additions it would have been 12.5%), with a similar effect on cache occupation of table entries accessed. For PIE builds of gas this also reduces the number of base relocations quite a bit (obviously independent of bitness).
* Update year range in copyright notice of binutils filesAlan Modra2023-01-011-1/+1
| | | | | | The newer update-copyright.py fixes file encoding too, removing cr/lf on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
* x86: rename CheckRegSize to CheckOperandSizeJan Beulich2022-12-211-3/+3
| | | | | | While originally indeed used for register size checking only, the attribute has been used for memory operand size checking as well already for quite a while, with more such uses recently having been added.
* x86: instantiate i386_{op,reg}tab[] in gas instead of in libopcodesJan Beulich2022-12-121-6/+1
| | | | | | | | | | | | Unlike many other architectures, x86 does not share an opcode table between assembly and disassembly. Any consumer of libopcodes would only ever access one of the two. Since gas is the only consumer of the assembly data, move it there. While doing so mark respective entities "static" in i386-gen (we may want to do away with i386_regtab_size altogether). This also shrinks the number of relocations to be processed for libopcodes.so by about 30%.
* x86: drop No_ldSufJan Beulich2022-12-011-3/+0
| | | | | With LONG_DOUBLE_MNEM_SUFFIX gone there'salso no use for No_ldSuf anymore.
* x86: drop FloatRJan Beulich2022-11-301-3/+0
| | | | | | | | | | | | | | There are just 4 templates using it, which can be easily identified by other means, as D is set only on a very limited number of FPU templates. Also move the respective conditional out of the code path taken by all "reverse match" insns (it probably should have been this way already before, to avoid the one conditional in the common case). With this the templates which had FloatR dropped no longer differ from their AT&T syntax + mnemonic counterparts - the only difference is now which of the two would be recognized. For this, however, we don't need two templates - we can simply arrange the condition for setting Opcode_FloatR accordingly.

* x86: fold special-operand insn attributes into a single enumJan Beulich2022-11-141-32/+22
| | | | | | | | Attributes which aren't used together in any single insn template can be converted from individual booleans to a single enum, as was done for a few other attributes before. This is more space efficient. Collect together all attributes which express special operand constraints (and which fit the criteria for folding).

* x86: re-work AVX-VNNI supportJan Beulich2022-10-201-3/+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.
* x86/Intel: restrict suffix derivationJan Beulich2022-09-301-6/+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.
* x86: also use D for MOVBEJan Beulich2022-08-031-1/+1
| | | | | | | | | | First of all rename the meanwhile misleading Opcode_SIMD_FloatD, as it has also been used for KMOV* and BNDMOV. Then simplify the condition selecting which form if "reversing" to use - except for the MOV to/from control/debug/test registers all extended opcode space insns use bit 0 (rather than bit 1) to indicate the direction (from/to memory) of an operation. With that, D can simply be set on the first of the two templates, while the other can be dropped.
* x86: re-order insn template fieldsJan Beulich2022-07-181-3/+11
| | | | | | | | | 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.)
* x86: make D attribute usable for XOP and FMA4 insnsJan Beulich2022-07-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | 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.
* x86: fold Disp32S and Disp32Jan Beulich2022-07-041-4/+1
| | | | | | | | | | | | | | | | | | | 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.
* x86: never set i386_cpu_flags' "unused" fieldJan Beulich2022-03-171-0/+4
| | | | | | | | | | | | | | 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.
* x86: drop L1OM/K1OM support from gasJan Beulich2022-03-171-6/+0

* [PATCH 1/2] Enable Intel AVX512_FP16 instructionsCui,Lili2021-08-051-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* x86: drop seg_entryJan Beulich2021-03-301-14/+1
| | | | | Use struct reg_entry instead for most purposes, with a separate array holding just the respective opcode prefix bytes.
* x86: drop REGNAM_{AL,AX,EAX}Jan Beulich2021-03-301-5/+0
| | | | | | The former two are unused anyway. And having such constants isn't very helpful either, when they live in a place where updating the register table wouldn't even allow noticing the need to adjust these constants.
* x86: adjust st(<N>) parsingJan Beulich2021-03-301-3/+3
| | | | | | | | 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.
* x86: shrink some struct insn_template fieldsJan Beulich2021-03-291-4/+4
| | | | | | | | | | | | Now that all base opcodes are only at most 2 bytes in size, shrink its template field to just as much. By also shrinking extension_opcode and operands to just what they really need, we can free up an entire 32-bit slot (plus 4 left bits past the bitfields themselves). At present this alters sizeof(struct insn_template) only for 32-bit builds. In 64-bit builds it instead leaves a padding hole that will allow to buffer future growth of other fields (opcode_modifier, cpu_flags, operand_types[]).
* x86: derive opcode length from opcode valueJan Beulich2021-03-241-3/+0
| | | | | | | | | | | | | | | | | | 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.
* x86: don't use opcode_length to identify pseudo prefixesJan Beulich2021-03-241-8/+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.
* x86: re-number PREFIX_0X<nn>Jan Beulich2021-03-231-5/+6
| | | | | | | 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.
* x86: re-order two fields of struct insn_templateJan Beulich2021-03-231-3/+3
| | | | | To facilitate a subsequent table parser change, re-order CPU flags and opcode modifier fields. No functional change intended.
* x86: split opcode prefix and opcode space representationJan Beulich2021-03-231-16/+21
| | | | | | | | 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.
* x86: fold some prefix related attributes into a single oneJan Beulich2021-03-091-20/+11
| | | | | | | 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.
