2020-08-28gas: Handle bad -gdwarf options, just like bad --gdwarf options.Mark Wielaard1-0/+7
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.

2016-02-26Properly implement STT_COMMONH.J. Lu1-0/+19
The BFD configure option, --enable-elf-stt-common, can't be to used to verify STT_COMMON implementation with the normal binutils build. Instead, this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF assembler/objcopy and adds -z common/-z nocommon to ld. A configure option, --enable-elf-stt-common, is added to gas to specify whether ELF assembler should generate common symbols with the STT_COMMON type by default. Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF common symbols. bfd/ PR ld/19645 * bfd.c (bfd): Change flags to 20 bits. (BFD_CONVERT_ELF_COMMON): New.

This patch makes the zlib-gabi option as compression default for gas, gold, ld and objcopy, instead of the zlib-gnu option whose outputs are incompatible with gABI. binutils/ * objcopy.c (copy_file): Set BFD_COMPRESS_GABI if not zlib-gnu. * doc/binutils.texi: Change --compress-debug-sections and --compress-debug-sections=zlib to zlib-gabi. binutils/testsuite/ * binutils-all/compress.exp: Update. gas/ * as.c (parse_args): Make --compress-debug-sections and --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * doc/as.texinfo: Change --compress-debug-sections and --compress-debug-sections=zlib to zlib-gabi. gold/ * compressed_output.cc (Output_compressed_section::set_final_data_size): Make --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * testsuite/Makefile.am (flagstest_compress_debug_sections.check): Expect ".debug_.*" with the SHF_COMPRESSED bit, instead of ".zdebug_". * testsuite/Makefile.in: Regenerated. ld/ * emultempl/elf32.em (gld${EMULATION_NAME}_handle_option): Make --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * ld.texinfo: Change --compress-debug-sections=zlib to zlib-gabi. ld/testsuite/ * ld-elf/zlibbegin.rS: Updated to .debug_.* with the SHF_COMPRESSED bit. * ld-elf/zlibnormal.rS: Likewise.
2015-06-28Remove COMPRESS_DEBUG_ZLIBH.J. Lu1-1/+1
COMPRESS_DEBUG_ZLIB isn't needed. This patch removes COMPRESS_DEBUG_ZLIB and replace COMPRESS_DEBUG_ZLIB with COMPRESS_DEBUG_GNU_ZLIB. bfd/ * bfd-in.h (compressed_debug_section_type): Remove COMPRESS_DEBUG_ZLIB. * bfd-in2.h : Regenerated. gas/ * as.c (parse_args): Replace COMPRESS_DEBUG_ZLIB with COMPRESS_DEBUG_GNU_ZLIB. * config/tc-i386.c (flag_compress_debug): Likewise. ld/ * emultempl/elf32.em (gld${EMULATION_NAME}_handle_option): Replace COMPRESS_DEBUG_ZLIB with COMPRESS_DEBUG_GNU_ZLIB.
2015-06-17gas: section name substitution sequenceNicolas Pitre1-0/+8
This patch adds the ability to automatically construct a section name based on the prior section. When gas is invoked with --sectname-subst, the occurrence of %S in a section name will be substituted by the name of the current section. For example: .macro exception_code .pushsection %S.exception [exception code here] .popsection .endm .text [code] exception_code [...] .section .init [init code] exception_code [...] The first and second exception_code invocations create the .text.exception and the .init.exception sections respectively. This is useful e.g. to discriminate between anciliary sections that are tied to .init code and can be discarded at run time when initialization is over vs anciliary sections tied to .text sections that need to stay resident. * as.c (show_usage): Document --sectname-subst. (parse_args): Add --sectname-subst. * as.h (flag_sectname_subst): New. * config/obj-elf.c (obj_elf_section_name): Add %S substitution. * doc/as.texinfo: Document it.
2015-04-08Add SHF_COMPRESSED support to gas and objcopyH.J. Lu1-4/+24
This patch adds --compress-debug-sections={none|zlib|zlib-gnu|zlib-gabi} options to gas and objcopy for ELF files. They control how DWARF debug sections are compressed. --compress-debug-sections=none is equivalent to --nocompress-debug-sections. --compress-debug-sections=zlib and --compress-debug-sections=zlib-gnu are equivalent to --compress-debug-sections. --compress-debug-sections=zlib-gabi compresses DWARF debug sections with SHF_COMPRESSED from the ELF ABI. No linker changes are required to support SHF_COMPRESSED. bfd/ * archive.c (_bfd_get_elt_at_filepos): Also copy BFD_COMPRESS_GABI bit. * bfd.c (bfd::flags): Increase size to 18 bits.

(bfd_get_full_section_contents): Call bfd_get_compression_header_size to get compression header size. (bfd_is_section_compressed): Renamed to ... (bfd_is_section_compressed_with_header): This. Add a pointer argument to return compression header size. (bfd_is_section_compressed): Use it.

Call bfd_get_compression_header_size to get compression header size. Don't rename section name for --compress-debug-sections=zlib-gabi. * config/tc-i386.c (compressed_debug_section_type): Set to COMPRESS_DEBUG_ZLIB. * doc/as.texinfo: Document --compress-debug-sections={none|zlib|zlib-gnu|zlib-gabi}. gas/testsuite/ * gas/i386/dw2-compressed-1.d: New file. * gas/i386/dw2-compressed-2.d: Likewise. * gas/i386/dw2-compressed-3.d: Likewise. * gas/i386/x86-64-dw2-compressed-2.d: Likewise. * gas/i386/i386.exp: Run dw2-compressed-2, dw2-compressed-1, dw2-compressed-3 and x86-64-dw2-compressed-2. ld/testsuite/ * ld-elf/compress.exp: Add a test for --compress-debug-sections=zlib-gabi.

2014-06-16Run write_object_file after errorsAlan Modra1-20/+39
This is to fix unitialised memory access when printing listings. Many targets don't initialise parts of insn frags or data frags that have fixups, relying on md_apply_fix to finalise the frag. Which is fine normally, but means we need to run write_object_file after errors, for listings. Otherwise MALLOC_PERTURB_=1 causes errors like: x86_64-linux +FAIL: i386 mpx-inval-1 x86_64-linux +FAIL: i386 inval-equ-1 x86_64-linux +FAIL: i386 x86-64-mpx-inval-1 Running write_object_file after errors requires some tweaking to the testsuite, since we then get extra errors reported from md_apply_fix. gas/ * write.h (subsegs_finish): Delete declaration. * write.c (subsegs_finish): Make static. (write_object_file): Call subsegs_finish from here. Don't print warning and error count here.. * as.c (main): ..do so here instead. Remove dead code for "no object file generated". Split out count strings to better support internationalisation. Don't call subsegs_finish. Tidy setting of "keep_it". Run write_object_file even after errors. (keep_it): Make static. * config/obj-elf.c (elf_frob_symbol): Remove assert.
