2022-07-21x86/Intel: correct AVX512F scatter insn element sizesJan Beulich2-32/+32
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).

2022-07-20gas/symbols: introduce md_resolve_symbolDmitry Selyutin2-0/+45
Assuming GMSD is a special operand, marked as O_md1, the code: .set VREG, GMSD .set REG, VREG extsw REG, 2 ...fails upon attempts to resolve the value of the symbol. This happens since machine-dependent values are not handled in the giant op switch. We introduce a custom md_resolve_symbol macro; the ports can use this macro to customize the behavior when resolve_symbol_value hits O_md operand.

2022-07-09gas: tc-tic54x.c hash tablesAlan Modra2-139/+223
Cleaning up the subsym_hash memory is a real pain. Keys and values entered into the table are quite diverse. In some cases the key is allocated and thus needs to be freed, in others the key is a const string. Values are similar, and in some cases not even a string. Tidy this by inserting a new subsym_ent_t that describes key/value type. This meant the math_hash table was no longer needed. The patch also tidies how math functions are called, those that are supposed to return int now no longer return their value in a float. * config/tc-tic54x.c (math_hash): Delete. (subsym_proc_entry): Move earlier, make proc a union, merge with.. (math_proc_entry): ..this. Delete type. (math_procs): Merge into subsym_procs. (subsym_ent_t): New. Use this type in subsym_hash..

2022-07-09gas: use notes_calloc in string hashAlan Modra6-8/+9
Using notes_calloc means all of the string hash table memory should now be freed before gas exits, even though htab_delete isn't called. This also means that the hash table free_f and del_f must be NULL, because freeing notes obstack memory results in all more recently allocated notes memory being freed too. So hash table resizing won't free any memory, and will be a little faster. Also, htab_delete won't do anything (and be quick about it). Since htab_traverse can also resize hash tables (to make another traversal faster if the table is largely empty), stop that happening when only one traversal is done. * as.h: Reorder hash.h after symbols.h for notes_calloc decl. * hash.h (str_htab_create): Use notes_calloc. Do not free. * symbols.c (resolve_local_symbol_values): Don't resize during hash table traversal. * config/obj-elf.c (elf_frob_file_after_relocs): Likewise. * config/tc-ia64.c (ia64_adjust_symtab, ia64_frob_file): Likewise. * config/tc-nds32.c (nds32_elf_analysis_relax_hint): Likewise.
2022-07-09gas: target string hash tablesAlan Modra9-81/+45
This allocates entries added to the string hash tables on the notes obstack, so that at least those do not leak. A followup patch will switch over the str_hash allocation to notes_calloc, which is why I haven't implemented deleting all the target string hash tables. * config/obj-coff-seh.c (get_pxdata_name, alloc_pxdata_item): Use notes obstack for string hash table entries. * config/tc-alpha.c (get_alpha_reloc_tag, md_begin): Likewise. * config/tc-h8300.c (md_begin): Likewise. * config/tc-ia64.c (dot_rot, dot_pred_rel, dot_alias): Likewise. * config/tc-nds32.c (nds32_relax_hint): Likewise. * config/tc-riscv.c (riscv_init_csr_hash): Likewise. * config/tc-score.c (s3_insert_reg): Likewise.

2022-07-09arc gas: don't leak arc_opcode_hash memoryAlan Modra2-1/+23
The arc opcode hash table has entries that have a realloc'd field. This doesn't lend itself to obstack allocation, so freeing must be done with a purpose built hashtab del_f. * config/tc-arc.c (arc_opcode_free): New function. (md_begin): Pass the above as del_f to htab_create_alloc. (arc_md_end): New function. * config/tc-arc.h (arc_md_end): Declare. (md_end): Define.
2022-07-09i386 gas: don't leak op_hash or reg_hash memoryAlan Modra3-3/+13
This tidies memory used by the two x86 gas string hash tables before exiting. I'm using a two-pronged approach, firstly the obvious call to htab_delete plus telling the libiberty/hashtab.c infrastructure to free tuples generated by str_hash_insert, and secondly putting the x86 core_optab memory on the notes obstack. It would be possible to free core_optab memory by using a custom hash table del_f on x86, as I do for arc, but a later patch will move all the string hash memory to the notes obstack. * config/tc-i386.c (md_begin): Use notes_alloc for core_optab. (386_md_end): New function. * config/tc-i386.h (386_md_end): Declare. (md_end): Define. * hash.h (str_htab_create): Pass free as del_f.

2022-07-09gas hash.h tidyAlan Modra2-30/+38
Only inline functions should be defined in hash.h, there's no benefit in having multiple copies of hash_string_tuple and eq_string_tuple. Also, use the table alloc_f when allocating tuples to be stored, so that these functions are usable with different memory allocation strategies. * hash.h (struct string_tuple, string_tuple_t): Move earlier. (string_tuple_alloc): Add table param, allocate using table alloc_f. (str_hash_insert): Adjust to suit. Call table->free_f when entry is not used. (hash_string_tuple, eq_string_tuple): Move to.. * hash.c: ..here.
2022-07-09gas: rename md_end to md_finishAlan Modra42-80/+84
Currently md_end is typically used for some final actions rather than freeing memory like other *_end functions. Rename it to md_finish, and rename target implementation. The renaming of target functions makes it possible to find them all with "grep md_finish", eg. md_mips_end is renamed to mips_md_finish, not md_mips_finish. This patch leaves a number of md_end functions unchanged, those that either do nothing or deallocate memory, and calls them late. The idea here is that target maintainers implement md_end functions to tidy memory, if anyone cares. Freeing persistent memory in gas is not at all important, except that it can hide more important memory leaks, those that happen once per some frequent gas operation, amongst these unimportant memory leaks. * as.c (main): Rename md_end to md_finish. * config/tc-alpha.c, * config/tc-alpha.h, * config/tc-arc.c, * config/tc-arc.h, * config/tc-arm.c, * config/tc-arm.h, * config/tc-csky.c, * config/tc-csky.h, * config/tc-ia64.c, * config/tc-ia64.h, * config/tc-mcore.c, * config/tc-mcore.h, * config/tc-mips.c, * config/tc-mips.h, * config/tc-mmix.c, * config/tc-mmix.h, * config/tc-msp430.c, * config/tc-msp430.h, * config/tc-nds32.c, * config/tc-nds32.h, * config/tc-ppc.c, * config/tc-ppc.h, * config/tc-pru.c, * config/tc-pru.h, * config/tc-riscv.c, * config/tc-riscv.h, * config/tc-s390.c, * config/tc-s390.h, * config/tc-sparc.c, * config/tc-sparc.h, * config/tc-tic4x.c, * config/tc-tic4x.h, * config/tc-tic6x.c, * config/tc-tic6x.h, * config/tc-v850.c, * config/tc-v850.h, * config/tc-xtensa.c, * config/tc-xtensa.h, * config/tc-z80.c, * config/tc-z80.h: Similarly. * output-file.c (output_file_close): Call md_end.
2022-07-09gas: set up notes obstack earlierAlan Modra3-11/+15
So that the notes obstack can be used for persistent storage in parse_args. * as.c (parse_args): Use notes_alloc and notes_strdup. (free_notes): New function.

2022-07-09dw2gencfi.c: use notes obstackAlan Modra1-12/+10
Use notes obstack for dwcfi_hash entries, and free table. Freeing the table makes memory checkers complain more about "definitely lost" memory as we've moved some from the "still reachable" category. That will be fixed with a later patch. * dw2gencfi.c (get_debugseg_name): Allocate on notes obstack. (alloc_debugseg_item): Likewise. (dwcfi_hash_find_or_make): Adjust failure path free. (cfi_finish): Delete dwfci_hash.

2022-07-09macro.c: use string hash from hash.h for macro_hashAlan Modra3-144/+29
Another case of duplicated hash.h code, the only minor difference being that macro->format_hash was created with 7 entries vs. str_hash with 16 entries. * macro.c (macro_init, define_macro): Use str_htab_create. (do_formals, define_macro, macro_expand_body): Use str_hash_insert (macro_expand_body): Use str_hash_find and str_hash_delete. (delete_macro): Likewise. (sub_actual, macro_expand, check_macro): Use str_hash_find. (expand_irp): Use str_htab_create and str_hash_insert. * macro.h (struct macro_struct): Tidy.

2022-07-09read.c: use string hash from hash.h for po_hashAlan Modra1-56/+7

2022-07-09gas: arm -mwarn-syms duplicatesAlan Modra2-5/+3
arm gas is only supposed to warn once per symbol for -mwarn-syms, but doesn't because the str_hash_find added with commit 629310abec88 always returns NULL. That's so because the str_hash_insert inserts a NULL value for the key,value pair. Let str_hash_insert do the job instead. * config/tc-arm.c (arm_tc_equal_in_insn): Correct already_warned logic. * testsuite/gas/arm/pr18347.s: Modify to generate duplicate warning without this patch.
2022-07-09Regenerate with automake-1.15.1Alan Modra3-733/+379
Until we update the recommended versions of autoconf/automake, files should be regenerated with automake-1.15.1 and autoconf-2.69. That's not because we think those versions are golden, and newer versions are bad. It's simply because maintainers want to be able to update configury files without trouble, and if someone regenerates files with automake-1.16.5 then --enable-maintainer-mode builds will hit errors: checking that generated files are newer than configure... configure.ac:26: error: version mismatch. This is Automake 1.15.1, configure.ac:26: but the definition used by this AM_INIT_AUTOMAKE configure.ac:26: comes from Automake 1.16.5. You should recreate configure.ac:26: aclocal.m4 with aclocal and run automake again. WARNING: 'automake-1.15' is probably too old. Correcting this requires regenerating the files by hand.

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.
2022-07-06x86: fold two switch() statements in match_template()Jan Beulich1-16/+3
I don't see why two of them were introduced (very long ago) using similar fall-through logic.
2022-07-06x86: fix 3-operand insn reverse-matchingJan Beulich3-18/+19
The middle operand would have gone entirely unchecked, allowing e.g. vmovss %xmm0, %esp, %xmm2 to assemble successfully, or e.g. vmovss %xmm0, $4, %xmm2 causing an internal error. Alongside dealing with this also drop a related comment, which hasn't been applicable anymore since the introduction of 3-operand patterns with D set (and which perhaps never had been logical to be there, as reverse-matched insns don't make it there in the first place).
2022-07-06x86: introduce a state stack for .archJan Beulich5-2/+159
When using just slightly non-trivial combinations of .arch, it can be quite useful to be able to go back to prior state without needing to re-invoke perhaps many earlier directives and without needing to invoke perhaps many "negative" ones. Like some other architectures allow saving (pushing) and restoring (popping) present/prior state. For now require the same .code<N> to be in effect for ".arch pop" that was in effect for the corresponding ".arch push". Also change the global "no_cond_jump_promotion" to be bool, to match the new struct field.
2022-07-06x86: generalize disabling of sub-architecturesJan Beulich1-235/+179
I never really understood upon what basis ".arch .no*" options were made available. Let's not have any "criteria" at all, and simply allow disabling of all of them. Then we also have all data for a sub-arch in a single place, as we now only need a single table.
2022-07-06x86: permit "default" with .archJan Beulich5-8/+85
So far there was no way to reset the architecture to that assembly would start with in the absence of any overrides (command line or directives). Note that for Intel MCU "default" is merely an alias of "iamcu". While there also zap a stray @item from the doc section, as noticed when inspecting the generated output (which still has some quirks, but those aren't easy to address without re-flowing almost the entire section).
2022-07-06x86: don't leak sub-architecture accumulated stringsJan Beulich1-0/+3
While it may not be necessary in i386_target_format() (but then setting the variable to NULL also wouldn't be necessary), at least in the other cases strings may already have accumulated.
2022-07-05x86: introduce fake processor type to mark sub-arch entries in cpu_arch[]Jan Beulich2-4/+10
This is in preparation of dropping the leading . from the strings. While there also move PROCESSOR_GENERIC{32,64} from the middle of AMD entries to near the top.
2022-07-05x86: macro-ize cpu_arch[] entriesJan Beulich1-308/+164
Putting individual elements behind macros, besides (imo) improving readability, will make subsequent (and likely also future) changes less intrusive. Utilize this right away to pack the table a little more tightly, by converting "skip" to bool and putting it earlier in a group of bitfields together with "len".
2022-07-05x86: de-duplicate sub-architecture strings accumulationJan Beulich1-38/+14
Introduce a helper function to replace 4 instances of similar code. Use reconcat() to cover the previously explicit free().
2022-07-04alloc gas seginfo on notes obstackAlan Modra3-18/+62
Lots of memory used in gas should go on this obstack. The patch also frees all the gas obstacks on exit, which isn't a completely trivial task. * subsegs.c (alloc_seginfo): New function. (subseg_change, subseg_get): Use it. (subsegs_end): New function. * as.h (subsegs_end): Declare. * output-file.c: Include subsegs.h (stash_frchain_obs): New function. (output_file_close): Save obstacks attached to output bfd before closing. Call subsegs_end with the array of obstacks.
