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.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-2/+2
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.

2019-12-27x86: consolidate Disp<NN> handling a littleJan Beulich1-1/+2
In memory operand addressing, which forms of displacement are permitted besides Disp8 is pretty clearly limited - outside of 64-bit mode, Disp16 or Disp32 only, depending on address size (MPX being special in not allowing Disp16), - in 64-bit mode, Disp32s or Disp64 without address size override, and solely Disp32 with one. Adjust assembler and i386-gen to match this, observing that templates already get adjusted before trying to match them against input depending on the presence of an address size prefix. This adjustment logic gets extended to all cases, as certain DispNN values should also be dropped when there's no such prefix. In fact behavior of the assembler, perhaps besides the exact diagnostics wording, should not differ between there being templates applicable to 64-bit and non-64-bit at the same time, or there being fully separate sets of templates, with their DispNN settings already reduced accordingly. This adjustment logic further gets guarded such that there wouldn't be and Disp<N> conversion based on address size prefix when this prefix doesn't control the width of the displacement (on branches other than absolute ones). These adjustments then also allow folding two MOV templates, which had been split between 64-bit and non-64-bits variants so far. Once in this area also - drop the bogus DispNN from JumpByte templates, leaving just the correct Disp8 there (compensated by i386_finalize_displacement() now setting Disp8 on their operands), - add the missing Disp32S to XBEGIN. Note that the changes make it necessary to temporarily mark a test as XFAIL; this will get taken care of by a subsequent patch. The failing parts are entirely bogus and will get replaced.
