2023-03-17gas: expose flag_macro_alternate globallyJan Beulich1-3/+1
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".
2023-03-17gas: use flag_mri directly in macro processingJan Beulich1-1/+1
Again with the removal of gasp about 20 years ago the extra level of indirection isn't necessary anymore. Drop macro.c's local variable and use the global flag directly.
2023-03-17gas: isolate macro_strip_at to macro.cJan Beulich1-5/+1
This removes a leftover from i960 support; with that nothing is left which would set macro_strip_at to non-zero, so the variable is converted to a #define (retaining the logic in case a new user would appear) and macro_init()'s respective parameter is dropped.
2023-03-17gas: drop function pointer parameter from macro_init()Jan Beulich1-23/+1
With the removal of gasp (about 20 years ago) the need for this kind- of-hook has disappeared. Go a step beyond merely moving the to be called function: Inline its contents right at the sole call site.

2023-03-10eh static dataAlan Modra1-0/+1
Fix another case of oss-fuzz tripping over gas static state, ie. starting over testing another input file with rubbish left uncleared in bss. size_end_sym pointed at garbage. * ehopt.c (get_cie_info): Delete forward declaration.

2023-03-03gas: default .debug section compression method adjustmentsJan Beulich1-2/+7
While commit b0c295e1b8d0 ("add --enable-default-compressed-debug- sections-algorithm configure option") adjusted flag_compress_debug's initializer, it didn't alter the default used when the command line option was specified with an (optional!) argument. This rendered help text inconsistent with actual behavior in certain configurations. As to help text - the default reported there clearly shouldn't be affected by a possible earlier --compress-debug-sections= option, so flag_compress_debug can't be used when emitting usage information.
2023-02-16Delete PROGRESS macrosAlan Modra1-9/+0
I don't see much point in cluttering the source with the PROGRESS macros, which of course do nothing at all with the definitions in progress.h. progress.h is unchanged apart from the copyright comment since commit d4d4c53c68f0 in 1994. binutils/ * ar.c: Don't include progress.h, or invoke PROGRESS macros. * nm.c: Likewise. * objcopy.c: Likewise. * objdump.c: Likewise. gas/ * as.h: Don't include progress.h. * as.c: Don't invoke PROGRESS macros. * write.c: Likewise. include/ * progress.h: Delete. ld/ * ldmain.c: Don't include progress.h, or invoke PROGRESS macros.
2023-02-16gas_initAlan Modra1-19/+20
Rename gas_late_init to plain gas_init, to reinforce the idea that this is where the bulk of gas initialisation belongs. Also reorder some initialisation. * as.c (gas_init): Rename from gas_late_init. Open output file and arrange for dump_statistics to be called here rather than in main. Create .gasversion. local symbol earlier, because we can.
2023-02-13Split off gas init to functionsAlan Modra1-72/+87
With some slight reordering. * as.c (gas_early_init, gas_late_init): New functions, split.. (main): ..from here.

2022-09-26binutils, gdb: support zstd compressed debug sectionsFangrui Song1-2/+11
PR29397 PR29563: Add new configure option --with-zstd which defaults to auto. If pkgconfig/libzstd.pc is found, define HAVE_ZSTD and support zstd compressed debug sections for most tools. * bfd: for addr2line, objdump --dwarf, gdb, etc * gas: support --compress-debug-sections=zstd * ld: support ELFCOMPRESS_ZSTD input and --compress-debug-sections=zstd * objcopy: support ELFCOMPRESS_ZSTD input for --decompress-debug-sections and --compress-debug-sections=zstd * gdb: support ELFCOMPRESS_ZSTD input. The bfd change references zstd symbols, so gdb has to link against -lzstd in this patch. If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this is too heavyweight, so don't do it for now. ``` % ld/ld-new a.o ld/ld-new: a.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... % ld/ld-new a.o --compress-debug-sections=zstd ld/ld-new: --compress-debug-sections=zstd: ld is not built with zstd support % binutils/objcopy --compress-debug-sections=zstd a.o b.o binutils/objcopy: --compress-debug-sections=zstd: binutils is not built with zstd support % binutils/objcopy b.o --decompress-debug-sections binutils/objcopy: zstd.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... ```
2022-07-09gas: rename md_end to md_finishAlan Modra1-2/+2
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.

parse_args uses getopt_long_only so it can handle long options both with double and single dash. But this means that some single dash options like -gdwarf-1 don't generate an error (unlike --gdwarf-1). This is especially confusing since there is also --gdwarf2, but no --gdwarf4 (it is --gdwarf-4). When giving -gdwarf4 the option is silently interpreted as -g (which set dwarf_version to 2). This causes some confusion for people who don't expect this and suddenly get DWARF2 instead of DWARF4 as they might expect. So make it so that the -gdwarf<unknown> creates an error, just like --gdwarf<unknown> would.

2019-11-28gas/riscv: Produce version 3 DWARF CIE by defaultAndrew Burgess1-4/+6
The flag controlling the default DWARF CIE version to produce now starts with the value -1. This can be modified with the command line flag as before, but after command line flag processing, in md_after_parse_args targets can, if the global still has the value -1, override this value. This gives a target specific default. If a CIE version is not select either by command line flag, or a target specific default, then some new code in dwarf2_init now select a global default. This remains as version 1 to match previous behaviour. This RISC-V has a target specific default of version provided, this make the return column uleb128, which means we can use all DWARF registers include CSRs. I chose to switch to version 3 rather than version 4 as this is most similar to the global default (version 1). Switching to version 4 adds additional columns to the CIE header. gas/ChangeLog: * as.c (flag_dwarf_cie_version): Change initial value to -1, and update comment. * config/tc-riscv.c (riscv_after_parse_args): Set flag_dwarf_cie_version if it has not already been set. * dwarf2dbg.c (dwarf2_init): Initialise flag_dwarf_cie_version if needed. * testsuite/gas/riscv/default-cie-version.d: New file. * testsuite/gas/riscv/default-cie-version.s: New file. ld/ChangeLog: * testsuite/ld-elf/eh5.d: Accept version 3 DWARF CIE.

2019-11-18gas: Add --gdwarf-cie-version command line flagAndrew Burgess1-0/+17
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. (flag_dwarf_cie_version): New variable. * as.h (flag_dwarf_cie_version): Declare. * dw2gencfi.c (output_cie): Switch from DW_CIE_VERSION to flag_dwarf_cie_version. * doc/as.texi (Overview): Document --gdwarf-cie-version. * NEWS: Likewise. * testsuite/gas/cfi/cfi.exp: Add new tests. * testsuite/gas/cfi/cie-version-0.d: New file. * testsuite/gas/cfi/cie-version-1.d: New file. * testsuite/gas/cfi/cie-version-2.d: New file. * testsuite/gas/cfi/cie-version-3.d: New file. * testsuite/gas/cfi/cie-version-4.d: New file. * testsuite/gas/cfi/cie-version.s: New file. include/ChangeLog: * dwarf2.h (DW_CIE_VERSION): Delete.

2019-09-19bfd_section_* macrosAlan Modra1-4/+4
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. 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.

This patch performs a run-time test that a shared libbfd.so has been compiled with the same size bfd_vma as that of apps using the library. On a 32-bit host it is easily possible to have one libbfd.so compiled to support 64-bit targets (or configured with --enable-64-bit-bfd) while another only supports 32-bit targets. The two libraries will have differently sized bfd_vma types, and if the wrong one is loaded all sorts of weird behaviour might be seen. bfd/ PR 23534 * init.c (BFD_INIT_MAGIC): Define.
