Not so long ago we started to insert these artificially when expanding certain macro-like constructs; zap them as cluttering what actually results from user input.

2022-08-01Get rid of fprintf_vma and sprintf_vmaAlan Modra1-7/+2
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.

2022-06-02gas read_a_source_file #APP processingAlan Modra1-91/+10
This fixes some horrible code using do_scrub_chars. What we had ran text through do_scrub_chars twice, directly in read_a_source_file and again via the input_scrub_include_sb call. That's silly, and since do_scrub_chars is a state machine, possibly wrong. More silliness is evident in the temporary malloc'd buffer for do_scrub_chars output, which should have been written directly to sbuf. So, get rid of the do_scrub_chars call and support functions, leaving scrubbing to input_scrub_include_sb. I did wonder about #NO_APP overlapping input_scrub_next_buffer buffers, but that should only happen if the string starts in one file and finishes in another. * read.c (scrub_string, scrub_string_end): Delete. (scrub_from_string): Delete. (read_a_source_file): Rewrite #APP processing.
2022-05-18gas: avoid octal numbers being accepted when processing .linefileJan Beulich1-0/+8
Compilers would put decimal numbers there, so I think we should treat finding octal numbers the same as finding bignums - ignore them as actually being comments of some very specific form.
2022-05-18gas: avoid bignum related errors when processing .linefileJan Beulich1-4/+15
Any construct which to the scrubber looks like a C preprocessor line/file "directive" is converted to .linefile, but the amount of checking the scrubber does is minimal (albeit it does let through only decimal digits for the line part of the contruct). Since the scrubber conversion is further tied to # being a line comment character, anything which upon closer inspection turns out not to be a line/file "directive" is supposed to be treated as a comment, i.e. ignored. Therefore we cannot use get_absolute_expression(), as this may raise errors. Open- code the function instead, treating everything not resulting in O_constant as a comment as well. Furthermore also bounds-check the parsed value. This bounds check tries to avoid implementation defined behavior (which may be the raising of an implementation defined signal), but for now makes the assumption that int has less than 64 bits. The way bfd_signed_vma (which is what offsetT aliases) is defined in bfd.h for the BFD64 case I cannot really see a clean way of avoiding this assumption. Omitting the #ifdef, otoh, would risk "condition is always false" warnings by compilers. Convert get_linefile_number() to return bool at this occasion as well.
2022-05-18gas: fold do_repeat{,_with_expander}()Jan Beulich1-42/+12
do_repeat_with_expander() already deals with the "no expander" case quite fine, so there's really little point having two functions. What it lacks compared with do_repeat() is a call to sb_build(), which can simply be moved (and the then redundant sb_new() be avoided). Along with this moving also flip if the main if()'s condition such that the "no expander" case is handled first.
2022-04-12gas: drop .appfile and .applineJan Beulich1-76/+61
These were used originally to represent "# <line> <file>" constructs inserted by (typically) compilers when pre-processing. Quite some time ago they were replaced by .linefile though. Since the original directives were never documented, we ought to be able to remove support for them. As a result in a number of case function parameter aren't used anymore and can hence be dropped.
2022-04-12gas: further adjust file/line handling for .macroJan Beulich1-6/+6
Commit 7992631e8c0b ("gas/Dwarf: improve debug info generation from .irp and alike blocks"), while dealing okay with actual assembly source files not using .file/.line and alike outside but not inside of .macro, has undue effects when the logical file/line pair was already overridden: Line numbers would continuously increment while processing the expanded macro, while the goal of the PR gas/16908 workaround is to keep the expansion associated with the line invoking the macro. However, as soon as enough state was overridden _inside_ the macro to cause as_where() to no longer fall back top as_where_physical(), honor this by resuming the bumping of the logical line number. Note that from_sb_is_expansion's initializer was 1 for an unknown reason. While renaming the variable and changing its type, also change the initializer to "expanding_none", which would have been "0" in the original code. Originally the initializer value itself wasn't ever used anyway (requiring sb_index != -1), as it necessarily had changed in input_scrub_include_sb() alongside setting sb_index to other than -1. Strictly speaking input_scrub_insert_line() perhaps shouldn't use expanding_none, yet none of the other enumerators fit there either. And then strictly speaking that function probably shouldn't exist in the first place. It's used only by tic54x.
2022-04-12gas: further adjust file/line handling for .irp and alikeJan Beulich1-4/+9
Commit 7992631e8c0b ("gas/Dwarf: improve debug info generation from .irp and alike blocks"), while dealing okay with actual assembly source files not using .file/.line and alike outside but not inside of .irp et al, has undue effects when the logical file/line pair was already overridden: Line numbers would continuously increment upon every iteration, thus potentially getting far off. Furthermore it left it to the user to actually insert .file/.line inside such constructs. Note though that before aforementioned change things weren't pretty either: Diagnostics (and debug info) would be associated with the directive terminating the iteration construct, rather than with the actual lines. Handle this automatically by simply latching the present line and then re-instating coordinates first thing on every iteration; note that the file can't change from what was previously pushed on the scrubber's state stack, and hence can be taken from there by using a new flavor of .linefile (which is far better memory-footprint-wise than recording the full path in the inserted directive). (This then leaves undisturbed any file/line control occurring in the body of the construct, as these will only be seen and processed afterwards.)
2022-03-20PR28979, internal error in demand_empty_rest_of_lineAlan Modra1-6/+14
The change in read_a_source_file prevents the particular testcase in the PR from triggering the assertion in demand_empty_rest_of_line. I've also removed the assertion. Nothing much goes wrong with gas if something else triggers it, so it's not worthy of an abort. I've also changed my previous patch to ignore_rest_of_line to allow that function to increment input_line_pointer past buffer_limit, like demand_empty_rest_of_line: The two functions ought to behave the same in that respect. Finally, demand_empty_rest_of_line gets a little hardening to prevent accesses past buffer_limit plus one. PR 28979 * read.c (read_a_source_file): Calculate known size for sbuf rather than calling strlen. (demand_empty_rest_of_line): Remove "know" check. Expand comment. Don't dereference input_line_pointer when past buffer_limit. (ignore_rest_of_line): Allow input_line_pointer to increment to buffer_limit plus one. Expand comment.
2022-03-17asan: buffer overflows after calling ignore_rest_of_lineAlan Modra1-9/+3
operand() is not a place that should be calling ignore_rest_of_line. ignore_rest_of_line shouldn't increment input_line_pointer if already at buffer limit. * expr.c (operand): Don't call ignore_rest_of_line. * read.c (s_mri_common): Likewise.

2022-02-16gas local label and dollar label handlingAlan Modra1-1/+1
Much of the gas source and older BFD source use "long" for function parameters and variables, when other types would be more appropriate. This patch fixes one of those cases. Dollar labels and numeric local labels do not need large numbers. Small positive itegers are usually all that is required. Due to allowing longs, it was possible for fb_label_name and dollar_label_name to overflow their buffers. * symbols.c: Delete unnecessary forward declarations.

2021-08-11gas: make 2nd argument of .dcb.* consistently optionalJan Beulich1-55/+75
Unlike the forms consuming/producing integer data, the floating point ones so far required the 2nd argument to be present, contrary to documentation. To avoid code duplication, split float_length() out of hex_float() (taking the opportunity to adjust error message wording).
2021-08-11x86: introduce .bfloat16 directiveJan Beulich1-0/+2
This is to be able to generate data acted upon by AVX512-BF16 and AMX-BF16 insns. While not part of the IEEE standard, the format is sufficiently standardized to warrant handling in config/atof-ieee.c. Arm, where custom handling was implemented, may want to leverage this as well. To be able to also use the hex forms supported for other floating point formats, a small addition to the generic hex_float() is needed. Extend existing x86 testcases.
2021-08-11x86: introduce .hfloat directiveJan Beulich1-0/+5
This is to be able to generate data passed to {,V}CVTPH2PS and acted upon by AVX512-FP16 insns. To be able to also use the hex forms supported for other floating point formats, a small addition to the generic hex_float() is needed. Extend existing x86 testcases.
2021-08-11x86/ELF: fix .tfloat output with hex inputJan Beulich1-4/+16
The ELF psABI-s are quite clear here: On 32-bit the data type is 12 bytes long (with 2 bytes of trailing padding), while on 64-bit it is 16 bytes long (with 6 bytes of padding). Make hex_float() capable of handling such padding. Note that this brings the emitted data size of .dc.x / .dcb.x in line also for non-ELF targets; so far they were different depending on input format (dec vs hex). Extend the existing x86 testcases.
2021-08-11x86/ELF: fix .ds.x outputJan Beulich1-2/+25
The ELF psABI-s are quite clear here: On 32-bit the underlying data type is 12 bytes long (with 2 bytes of trailing padding), while on 64-bit it is 16 bytes long (with 6 bytes of padding). Make s_space() capable of handling 'x' (and 'p') type floating point being other than 12 bytes wide (also adjusting documentation). This requires duplicating the definition of X_PRECISION in the target speciifc header; the compiler would complain if this was out of sync with config/atof-ieee.c. Note that for now padding space doesn't get separated from actual storage, which means that things will work correctly only for little- endian cases, and which also means that by specifying large enough numbers padding space can be set to non-zero. Since the logic is needed for a single little-endian architecture only for now, I'm hoping that this might be acceptable for the time being; otherwise the change will become more intrusive. Note also that this brings the emitted data size of .ds.x vs .tfloat in line for non-ELF targets as well; the issue will be even more obvious when further taking into account a subsequent patch fixing .dc.x/.dcb.x (where output sizes currently differ depending on input format). Extend existing x86 testcases.

2021-06-16gas: fix hex float parsing from .dcb.? directivesJan Beulich1-71/+53
Unlike for .dc.? the parsing here failed to skip the colon before calling hex_float(). To avoid both variants of parsing going out of sync again, introduce a helper used by both.
2021-06-16gas: fix overflow diagnosticsJan Beulich1-9/+2
While the logic in fixup_segment() so far was off by 1 for fixups dealing with quantities without known signedness, thus failing to report an overflow when e.g. a byte-sized resulting value is -0x100, the logic in emit_expr_with_reloc() reported an overflow even on large negative values when the respective positive ones would not be warned about, and when fixup_segment() wouldn't do so either. Such diagnostics all ought to follow a similar pattern of what value range is acceptable. (If expressions' X_unsigned was reliably set, emit_expr_with_reloc()'s checking might make sense to tighten based on that flag.) Note that with commit 80aab57939a0 ("Changes to let cons handle bignums like general expressions") having added handling of nbytes > sizeof(valueT) in the O_constant case, converting to O_big, the setting to zero of "hibit" had become dead. With "hibit" no longer used, this code now gets dropped altogether. But additionally a respective know() gets inserted.

2021-06-14gas: drop TC_ADDRESS_BYTES conditionalsJan Beulich1-4/+0
I've been repeatedly confused by, in particular, the .dc.a potable[] entry being conditional. Grepping in gas/config/ reveals only very few targets actually #define-ing it. But as of 7be1c4891a20 the symbol is always defined, so #ifdef-s are pointless (and, as said, potentially confusing). Also adjust documentation to reflect this.

2021-01-07ELF: Don't generate unused section symbolsH.J. Lu1-0/+3
For ELF targets, section symbols are required only for relocations. With -ffunction-sections -fdata-sections, there can be many unused section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are With unused section symbols : 39411698 bytes Without unused section symbols: 39227002 bytes The unused section symbols in libstdc++.a occupy more than 180 KB. Add BSF_SECTION_SYM_USED to indicate if a section symbol should be included in the symbol table. The BSF_SECTION_SYM_USED should be set if the section symbol is used for relocation or the section symbol is always included in the symbol table. Add keep_unused_section_symbols to bfd_target to indicate if unused section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS is defined as FALSE, unused ection symbols will be removed. Tested on Linux/x86. Other ELF backends need to: 1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE. 2. Mark used section symbols in assembler backend. 3. Remove unused section symbols from expected assembler and linker outputs. bfd/ PR 27109 * aix386-core.c (core_aix386_vec): Initialize keep_unused_section_symbol to TARGET_KEEP_UNUSED_SECTION_SYMBOLS. * aout-target.h (MY (vec)): Likewise. * binary.c (binary_vec): Likewise. * cisco-core.c (core_cisco_be_vec): Likewise.

Inserting with replacement is wrong for some gas hash table uses. This patch implements an htab_insert that conditionally replaces, and similarly for str_hash_insert. str_hash_insert with replace=0 is roughly equivalent to the older hash_insert, and str_hash_insert with replace=1 to the older hash_jam, but return values are different. I found it useful to know whether the slot was occupied prior to inserting/replacing. I've also reinstated the fatal errors on messing up opcode tables with duplicates.
