* gas: add .cv_ucomp and .cv_scomp pseudo-directivesMark Harmstone2024-11-131-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add .cv_ucomp and .cv_scomp pseudo-directives for object files for Windows targets, which encode compressed CodeView integers according to the algorithm in CVCompressData in https://github.com/Microsoft/microsoft-pdb/blob/master/include/cvinfo.h. This is essentially Microsoft's answer to the LEB128, though used in far fewer places. CodeView uses these to encode the "binary annotations" in the S_INLINESITE symbol, which express the relationship between code offsets and line numbers in inlined functions. This has to be done in the assembler as GCC doesn't know how many bytes each instruction takes up. There's no equivalent for this for MSVC or LLVM, as in both cases the assembler and compiler are integrated. .cv_ucomp represents an unsigned big-endian integer between 0 and 0x1fffffff, taking up 1, 2, or 4 bytes: Value between 0 and 0x7f: 0aaaaaaa -> 0aaaaaaa (identity-mapped) Value between 0x80 and 0x3fff: 00aaaaaa bbbbbbbb -> 10aaaaaa bbbbbbbb Value between 0x4000 and 0x1fffffff: 000aaaaa bbbbbbbb ccccccccc dddddddd -> 110aaaaa bbbbbbbb ccccccccc dddddddd .cv_scomp represents a signed big-endian integer between -0xfffffff and 0xfffffff, encoded according to EncodeSignedInt32 in cvinfo.h. The absolute value of the integer is shifted left one bit, the LSB set for a negative value, and the result expressed as if it were a .cv_ucomp: cv_scomp(x) = cv_ucomp((abs(x) << 1) | (x < 0 ? 1 : 0))
* gas: minor reformatting in command line help and docMatthieu Longo2024-07-181-1/+1
| | | | | | | | | | | - help message: add a comma between the short and long option - as doc: - brief summary of how to invoke gas: separate [-w] [-x] on a new line as those two options have nothing to do with the warning options. - reordering of the warning options to have the same order as the listing. - no-warn option description: change an "and" to a "or", as it is either the short or long option to use, but not both at the same time. - remove trailing whitespaces.
* gas: multi-byte warning adjustmentsJan Beulich2024-07-111-1/+1
| | | | | | | | | | | | First input_scrub_next_buffer()'s invocation was wrong, leading to input only being checked from the last newline till the end of the current buffer. Correcting the invocation, however, leads to duplicate checking unless -f (or the #NO_APP equivalent thereof) is in effect. Move the invocation to input_file_give_next_buffer(), to restrict it accordingly. Then, when macros contain multi-byte characters, warning about them again in every expansion isn't useful. Suppress such warnings from sb_scrub_and_add_sb().
* gas: add new command line option --scfi=experimentalIndu Bhagat2024-01-151-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the command line option --scfi=experimenta is passed to the GNU assembler, it will synthesize DWARF call frame information (CFI) for the input assembly. The option --scfi=experimental will also ignore most of the existing .cfi_* directives, if already contained in the provided input file. Only the following CFI directives will not be ignored: - .cfi_sections, - .cfi_label, - .cfi_signal_frame To use SCFI, a target will need to: - define TARGET_USE_SCFI and TARGET_USE_GINSN, and other necessary definitions, - provide means to help GAS understand the target specific instruction semantics by creating ginsns. The upcoming support for SCFI is inteded to be experimental, hence the option --scfi=experimental. The --scfi= may see more options like --scfi=[all,none] added in future, once the SCFI support in GAS is mature and robust. The offering may also see for example, an --scfi=inline option for dealing with inline asm may be added in the future. In --scfi=inline option, the GNU assembler may consume (and not ignore) the compiler generated CFI for the code surrounding the inline asm. Also document the option. gas/ * as.c (show_usage): Add support for --scfi=experimental. (parse_args): Likewise. * as.h (enum synth_cfi_type): Define new type. * doc/as.texi: Document the new option.
* Update year range in copyright notice of binutils filesAlan Modra2024-01-041-1/+1
| | | | | | | | | | | | | Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.
* gas: make .nops output visible in listingJan Beulich2023-10-231-1/+3
| | | | | | Due to using a different frag type (in turn due to storing data differently), making the resulting code appear in listings requires special handling.
* gas: expose flag_macro_alternate globallyJan Beulich2023-03-171-0/+3
| | | | | | | | Yet again with the removal of gasp about 20 years ago this extra level of indirection isn't necessary anymore either. Drop macro.c's local variable and make as.c's global. While doing the conversion, switch the variable to "bool".

* gas: re-work line number tracking for macros and their expansionsJan Beulich2022-12-131-0/+11
| | | | | | | | | | | | | | | | | | The PR gas/16908 workaround aimed at uniformly reporting line numbers to reference macro invocation sites. As mentioned in a comment this may be desirable for small macros, but often isn't for larger ones. As a first step improve diagnostics to report both locations, while aiming at leaving generated debug info unaltered. Note that macro invocation context is lost for any diagnostics issued only after all input was processed (or more generally for any use of as_*_where(), as the functions can't know whether the passed in location is related to [part of] the present stack of locations). To maintain the intended workaround behavior for PR gas/16908, a new as_where() is introduced to "look through" macro invocations, while the existing as_where() is renamed (and used in only very few places for now). Down the road as_where() will likely want to return a list of (file,line) pairs.

* gas: generate .sframe from CFI directivesIndu Bhagat2022-11-151-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently supported for x86_64 and aarch64 only. [PS: Currently, the compiler has not been adapted to generate ".cfi_sections" with ".sframe" in it. The newly added command line option of --gsframe provides an easy way to try out .sframe support in the toolchain.] gas interprets the CFI directives to generate DWARF-based .eh_frame info. These internal DWARF structures are now consumed by gen-sframe.[ch] sub-system to, in turn, create the SFrame unwind information. These internal DWARF structures are read-only for the purpose of SFrame unwind info generation. SFrame unwind info generation does not impact .eh_frame unwind info generation. Both .eh_frame and .sframe can co-exist in an ELF file, if so desired by the user. Recall that SFrame unwind information only contains the minimal necessary information to generate backtraces and does not provide information to recover all callee-saved registers. The reason being that callee-saved registers other than FP are not needed for stack unwinding, and hence are not included in the .sframe section. Consequently, gen-sframe.[ch] only needs to interpret a subset of DWARF opcodes in gas. More details follow. [Set 1, Interpreted] The following opcodes are interpreted: - DW_CFA_advance_loc - DW_CFA_def_cfa - DW_CFA_def_cfa_register - DW_CFA_def_cfa_offset - DW_CFA_offset - DW_CFA_remember_state - DW_CFA_restore_state - DW_CFA_restore [Set 2, Bypassed] The following opcodes are acknowledged but are not necessary for generating SFrame unwind info: - DW_CFA_undefined - DW_CFA_same_value Anything else apart from the two above-mentioned sets is skipped altogether. This means that any function containing a CFI directive not in Set 1 or Set 2 above, will not have any SFrame unwind information generated for them. Holes in instructions covered by FREs of a single FDE are not representable in the SFrame unwind format. As few examples, following opcodes are not processed for .sframe generation, and are skipped: - .cfi_personality* - .cfi_*lsda - .cfi_escape - .cfi_negate_ra_state - ... Not processing .cfi_escape, .cfi_negate_ra_state will cause SFrame unwind information to be absent for SFrame FDEs that contain these CFI directives, hence affecting the asynchronicity. x86-64 and aarch64 backends need to have a few new definitions and functions for .sframe generation. These provide gas with architecture specific information like the SP/FP/RA register numbers and an SFrame-specific ABI marker. Lastly, the patch also implements an optimization for size, where specific fragments containing SFrame FRE start address and SFrame FDE function are fixed up. This is similar to other similar optimizations in gas, where fragments are sized and fixed up when the associated symbols can be resolved. This optimization is controlled by a #define SFRAME_FRE_TYPE_SELECTION_OPT and should be easy to turn off if needed. The optimization is on by default for both x86_64 and aarch64.

* PR29466, APP/NO_APP with .linefileAlan Modra2022-08-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 53f2b36a54b9 exposed a bug in sb_scrub_and_add_sb that could result in losing input. If scrubbing results in expansion past the holding capacity of do_scrub_chars output buffer, then do_scrub_chars stashes the extra input for the next call. That call never came because sb_scrub_and_add_sb wrongly decided it was done. Fix that by allowing sb_scrub_and_add_sb to see whether there is pending input. Also allow a little extra space so that in most cases we won't need to resize the output buffer. sb_scrub_and_add_sb also limited output to the size of the input, rather than the actual output buffer size. Fixing that resulted in a fail of gas/testsuite/macros/dot with an extra warning: "end of file not at end of a line; newline inserted". OK, so the macro in dot.s really does finish without end-of-line. Apparently the macro expansion code relied on do_scrub_chars returning early. So fix that too by adding a newline if needed in macro_expand_body.

* gas: use notes_calloc in string hashAlan Modra2022-07-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

* gas: Add --gdwarf-cie-version command line flagAndrew Burgess2019-11-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a flag to control the version of CIE that is generated. By default gas produces CIE version 1, and this continues to be the default after this patch. However, a user can now provide --gdwarf-cie-version=NUMBER to switch to either version 3 or version 4 of CIE, version 2 was never released, and so causes an error as does any number less than 1 or greater than 4. Producing version 4 CIE requires two new fields to be added to the CIE, an address size field, and an segment selector field. For a flat address space the DWARF specification indicates that the segment selector should be 0, and the address size fields just contains the address size in bytes. For now we support 4 or 8 byte addresses, and the segment selector is always produced as 0. At some future time we might need to allow targets to override this. gas/ChangeLog: * as.c (parse_args): Parse --gdwarf-cie-version option.

* [Patch][binutils] Generic support for parsing numbers in bfloat16 format [5/X]Matthew Malcomson2019-11-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, This patch is part of a series that adds support for Armv8.6-A (Matrix Multiply and BFloat16 extensions). This patch contains some general refactoring of the atof_ieee function, exposing a function that allows a higher level of control over the format of IEEE-like floating point numbers. This has been done in order to be able to add a directive for assembling floating point literals in the bfloat16 format in the following patches. Committed on behalf of Mihail Ionescu. Tested on arm-none-eabi, arm-none-linux-gnueabihf, aarch64-none-elf and aarch64-none-linux-gnuwith no issues. gas/ChangeLog: 2019-10-21 Mihail Ionescu <mihail.ionescu@arm.com> 2019-10-21 Barnaby Wilks <barnaby.wilks@arm.com> * as.h (atof_ieee_detail): Add prototype for atof_ieee_detail function. (atof_ieee): Move some code into the atof_ieee_detail function. (atof_ieee_detail): Add function that provides a higher level of control over generating IEEE-like numbers. Is it ok for trunk?

The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

* Add .nop assembler directiveH.J. Lu2018-02-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits SIZE bytes filled with no-op instructions. SIZE is absolute expression. The optional CONTROL byte controls how no-op instructions should be generated. If the comma and @var{control} are omitted, CONTROL is assumed to be zero. For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size limit of a single no-op instruction. The valid values of CONTROL byte are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode, between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit is set to the maximum supported size. 2 new relax states, rs_space_nop and rs_fill_nop, are added to enum _relax_state, which are similar to rs_space and rs_fill, respectively, but they fill with no-op instructions, instead of a single byte. A target backend must override the default md_generate_nops to generate proper no-op instructions. Otherwise, an error of unimplemented .nop directive will be issued whenever .nop directive is used. * NEWS: Mention .nop directive. * as.h (_relax_state): Add rs_space_nop and rs_fill_nop. * read.c (potable): Add .nop.
