The commit 1369522f36eece1b37139a81f7f2139ba3915172 ("Recognize the new ELF
compression type for ZSTD.") added the new ELF compression type but it
accidentally broke a GAS testcase. Since testing for the section type
"2048" (SHF_COMPRESSED) is not going to be portable in the long term, it
now tests SHF_LINK_ORDER ("128") instead.
Using SHF_LINK_ORDER (with possibly sh_link == 0) is an idea by Jan Beulich.
gas/ChangeLog:
* testsuite/gas/elf/section10.s: Use SHF_LINK_ORDER to test
mixed numeric and alpha values.
* testsuite/gas/elf/section10.d: Reflect the change above.

BFD_VMA_FMT can't be used in format strings that need to be
translated, because the translation won't work when the type of
bfd_vma differs from the machine used to compile .pot files. We've
known about this for a long time, but patches slip through review.
So just get rid of BFD_VMA_FMT, instead using the appropriate PRId64,
PRIu64, PRIx64 or PRIo64 and SCN variants for scanf. The patch is
mostly mechanical, the only thing requiring any thought is casts
needed to preserve PRId64 output from bfd_vma values, or to preserve
one of the unsigned output formats from bfd_signed_vma values.

- Drop the rounding type check: We're past template matching, and none
of the involved insns support embedded rounding.
- Drop the extension opcode check: None of the involved opcodes have
variants with it being other than None.
- Instead check opcode space, even if just to be on the safe side going
forward.
- Reduce the number of comparisons by folding two groups.

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.

This patch extends assembler support for the use of register names to
allow for pseudo-registers, e.g. ra_auth_code register.
This is done particularly with CFI directives in mind, allowing for
expressions of the type:
.cfi_register ra_auth_code, 12

* config/tc-arm.c (tc_arm_regname_to_dw2regnum): Add
REG_TYPE_PSEUDO handling.

This patch modifies the internal `struct reg_entry' numbering of DWARF
pseudo-registers to match values assigned in DWARF standards (see "4.1
DWARF register names" in [1])so ra_auth_code goes from 12 to 143 and
amends the unwinder .save directive-processing code to correctly handle
mixed register-type save directives.
The mechanism for splitting the register list is also re-written to
comply with register ordering on push statements, being that registers
are stored on the stack in numerical order, with the lowest numbered
register at the lowest address [2].
Consequently, the parsing of the hypothetical directive
.save{r4-r7, r10, ra_auth_core, lr}
has been changed such as rather than producing
.save{r4-r7, r10}
.save{ra_auth_code}
.save{lr}
as was the case with previous implementation, now produces:
.save{lr}
.save{ra_auth_code}
.save{r4-r7, r10}

Without it in 16-bit mode a pointless operand size prefix would be
emitted.

This syntactic sugar is present in both classical and emerging
architectures, like Alpha, SPARC and RISC-V, and assembler macros
doing the same thing can already be found in the wild e.g. [1], proving
the feature's popularity. It's better to provide support directly in the
assembler so downstream users wouldn't have to re-invent this over and
over again.

Also re-order the jump/branch opcodes while at it, so that insns are

These two macros print either a 16 digit hex number or an 8 digit
hex number. Unfortunately they depend on both target and host, which
means that the output for 32-bit targets may be either 8 or 16 hex
digits.
Replace them in most cases with code that prints a bfd_vma using
PRIx64. In some cases, deliberately lose the leading zeros.
This change some output, notably in base/offset fields of m68k
disassembly which I think looks better that way, and in error
messages. I've kept leading zeros in symbol dumps (objdump -t)
and in PE header dumps.

This commit enables disassembler styling for AArch64. After this
commit it is possible to have objdump style AArch64 disassembler
output (using --disassembler-color option). Once the required GDB
patches are merged, GDB will also style the disassembler output.
The changes to support styling are mostly split between two files
opcodes/aarch64-dis.c and opcodes/aarch64-opc.c.
The entry point for the AArch64 disassembler can be found in
aarch64-dis.c, this file handles printing the instruction mnemonics,
and assembler directives (e.g. '.byte', '.word', etc). Some operands,
mostly relating to assembler directives are also printed from this
file. This commit changes all of this to pass through suitable
styling information.
However, for most "normal" instructions, the instruction operands are
printed using a two step process. From aarch64-dis.c, in the
print_operands function, the function aarch64_print_operand is called,
this function is in aarch64-opc.c, and converts an instruction operand
into a string. Then, back in print_operands (aarch64-dis.c), the
operand string is printed.
Unfortunately, the string returned by aarch64_print_operand can be
quite complex, it will include syntax elements, like '[' and ']', in
addition to register names and immediate values. In some cases, a
single operand will expand into what will appear (to the user) as
multiple operands separated with a ','.
This makes the task of styling more complex, all these different
components need to by styled differently, so we need to get the
styling information out of aarch64_print_operand in some way.
The solution that I propose here is similar to the solution that I
used for the i386 disassembler.
Currently, aarch64_print_operand uses snprintf to write the operand
text into a buffer provided by the caller.
What I propose is that we pass an extra argument to the
aarch64_print_operand function, this argument will be a structure, the
structure contains a callback function and some state.
When aarch64_print_operand needs to format part of its output this can
be done by using the callback function within the new structure, this
callback returns a string with special embedded markers that indicate
which mode should be used for each piece of text. Back in
aarch64-dis.c we can spot these special style markers and use this to
split the disassembler output up and apply the correct style to each
piece.
To make aarch64-opc.c clearer a series of new static functions have
been added, e.g. 'style_reg', 'style_imm', etc. Each of these
functions formats a piece of text in a different style, 'register' and
'immediate' in this case.
Here's an example taken from aarch64-opc.c of the new functions in
use:
snprintf (buf, size, "[%s, %s]!",
style_reg (styler, base),
style_imm (styler, "#%d", opnd->addr.offset.imm));
The aarch64_print_operand function is also called from the assembler
to aid in printing diagnostic messages. Right now I have no plans to
add styling to the assembler output, and so, the callback function
used in the assembler ignores the styling information and just returns
an plain string.
I've used the source files in gas/testsuite/gas/aarch64/ for testing,
and have manually gone through and checked that the styling looks
reasonable, however, I'm not an AArch64 expert, so it is possible that
the odd piece is styled incorrectly. Please point out any mistakes
I've made.
With objdump disassembler color turned off, there should be no change
in the output after this commit.

The original approach has resulted in anomalies when . is involved in an
operand of one of the affected insns. We cannot leave . unresolved, or
else it'll be resolved at the end of assembly, then pointing to the
address of a section rather than at the insn of interest. Undo part of
the original change and instead check whether a relocation cannot be
omitted in md_apply_fix().
By resolving the expressions again, equates (see the adjustment of the
respective testcase) will now be evaluated, and hence relocations
against absolute addresses be emitted. This ought to be okay as long as
the equates aren't global (and hence can't be overridden). If a need
for such arises, quite likely the only way to address this would be to
invent yet another expression evaluation mode, leaving everything
_except_ . un-evaluated.
There's a further anomaly in how transitive equates are handled. In
.set x, 0x12345678
.eqv bar, x
foo:
adrp x0, x
add x0, x0, :lo12:x
adrp x0, bar
add x0, x0, :lo12:bar
the first two relocations are now against *ABS*:0x12345678 (as said
above), whereas the latter two relocations would be against x. (Before
the change here, the first two relocations are against x and the latter
two against bar.) But this is an issue seen elsewhere as well, and would
likely require adjustments in the target-independent parts of the
assembler instead of trying to hack around this for every target.

Assuming GMSD is a special operand, marked as O_md1, the code:

...fails upon attempts to resolve the value of the symbol. This happens

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.

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.

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.

Only inline functions should be defined in hash.h, there's no benefit

strategies.

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-z80.c, * config/tc-z80.h: Similarly.
* output-file.c (output_file_close): Call md_end.

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.
(main): Init notes obstack, and arrange to be freed on exit.
* read.c (read_begin): Don't init notes obstack.
(read_end): Free cond_obstack.
* subsegs.c (subsegs_end): Don't free cond_obstack or notes.
|
|
itbl_files seems to be debug code. Get rid of it.
* as.c (struct itbl_file_list): Delete.
(itbl_files): Delete.
(parse_args): Don't keep itbl_files list.
|
|
* macro.c (macro_end): New function.

* symbols.h (symbol_end): Declare.
* output-file.c (output_file_close): Call new *_end functions.

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.
|
|
* expr.c (make_expr_symbol): Use notes_alloc.
|
|
* read.c (assign_symbol): Use notes_calloc for dummy_frag.
|
|
* read.c (s_include): Use notes obstack for path mem.
|
|
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.
(struct macro_hash_entry, macro_hash_entry_t, hash_macro_entry),
(eq_macro_entry, macro_entry_alloc, macro_entry_find),
(struct formal_hash_entry, formal_hash_entry_t),
(hash_formal_entry, eq_formal_entry, formal_entry_alloc),
(formal_entry_find): Delete.
* config/tc-iq2000.c (iq2000_add_macro): Use str_htab_create
and str_hash_insert.
|
|
po_hash code duplicates the str_hash code in hash.h for no good reason.
* read.c (struct po_entry, po_entry_t): Delete.
(hash_po_entry, eq_po_entry, po_entry_alloc, po_entry_find): Delete.
(pop_insert): Use str_hash_insert.
(pobegin): Use str_htab_create.
(read_a_source_file, s_macro): Use str_hash_find.
|
|
read_symbol_name mallocs the string it returns. Free it when done.
* read.c (read_symbol_name): Free name on error path.
* config/tc-ppc.c (ppc_GNU_visibility): Free name returned from
read_symbol_name.
(ppc_extern, ppc_globl, ppc_weak): Likewise.
|
|
This is mostly a tidy with the aim of being able to free
out_file_name, but it does fix a possible attempt to unlink the output
file twice (not that that matters).
* as.h (keep_it): New global.
* as.c (keep_it): Delete.
(close_output_file): Delete, merged into..
* output-file.c (output_file_close): ..here. Delete parameter.
* output-file.h (output_file_close): Update prototype.
|
|
Makes it a little easier to use the notes obstack for persistent
storage.
* as.h (gas_mul_overflow): Define.
* symbols.h (notes_alloc, notes_calloc, notes_memdup),
(notes_strdup, notes_concat, notes_free): Declare.
* symbols.c (notes_alloc, notes_calloc, notes_memdup),
(notes_strdup, notes_concat, notes_free): New functions.
(save_symbol_name): Use notes_strdup.
(symbol_create, local_symbol_make, local_symbol_convert),
(symbol_clone, decode_local_label_name): Use notes_alloc.

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.

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.
