Jan Beulich	37cea58867	x86: re-order insn template fields 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.)	4 years ago
Jan Beulich	8bd915b770	x86: make D attribute usable for XOP and FMA4 insns 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.	4 years ago
Jan Beulich	a775efc84d	x86: fold Disp32S and Disp32 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.	4 years ago
Jan Beulich	13ed231a0f	x86: never set i386_cpu_flags' "unused" field 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.	4 years ago
Jan Beulich	c085ab00c7	x86: drop L1OM/K1OM support from gas This was only rudimentary support anyway; none of the sub-architecture specific insns were ever supported.	4 years ago

Alan Modra	a2c5833233	Update year range in copyright notice of binutils files 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.	4 years ago
Cui,Lili	0cc7872125	[PATCH 1/2] Enable Intel AVX512_FP16 instructions 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.

Jan Beulich	5e0423804a	x86: drop seg_entry Use struct reg_entry instead for most purposes, with a separate array holding just the respective opcode prefix bytes.	5 years ago
Jan Beulich	3468486226	x86: drop REGNAM_{AL,AX,EAX} 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.	5 years ago
Jan Beulich	6288d05f11	x86: adjust st(<N>) parsing 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.	5 years ago
Jan Beulich	9df6f676c2	x86: shrink some struct insn_template fields 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[]).	5 years ago
Jan Beulich	9a182d0461	x86: derive opcode length from opcode value 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.	5 years ago
Jan Beulich	311845694b	x86: don't use opcode_length to identify pseudo prefixes 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.	5 years ago
Jan Beulich	b933fa4b5d	x86: re-number PREFIX_0X<nn> 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.	5 years ago
Jan Beulich	dac10fb0d1	x86: re-order two fields of struct insn_template To facilitate a subsequent table parser change, re-order CPU flags and opcode modifier fields. No functional change intended.	5 years ago
Jan Beulich	441f6aca39	x86: split opcode prefix and opcode space representation Commit `8b65b8953a` ("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.	5 years ago
Jan Beulich	742732c7f0	x86: fold some prefix related attributes into a single one 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.	5 years ago

Jan Beulich	8a6fb3f9bb	x86: restrict use of register aliases Register aliases (created e.g. via .set) check their target register at the time of creation of the alias. While this makes sense, it's not enough: The underlying register must also be "visible" at the time of use. Wrong use of such aliases would lead to internal errors in e.g. add_prefix() or build_modrm_byte(). Split the checking part of parse_real_register() into a new helper function and use it also from the latter part of parse_register() (at the same time replacing a minor open coded part of it). Since parse_register() returning NULL already has a meaning, a fake new "bad register" indicator gets added, which all callers need to check for.	6 years ago
