2023-01-10Set dwarf2 stash pointer earlierAlan Modra1-2/+1
This fixes a memory leak in the vanishingly rare cases (found by fuzzers of course) when something goes wrong in the save_section_vma, htab_create_alloc or alloc_trie_leaf calls before *pinfo is written. If *pinfo is not written, _bfd_dwarf2_cleanup_debug_info won't be able to free that memory. * dwarf2.c (_bfd_dwarf2_slurp_debug_info): Save stash pointer on setting up stash.
2023-01-10peXXigen.c sanity checksAlan Modra1-44/+52
Also fix a memory leak, and make some style changes. I tend to read (sizeof * x) as a multiplication of two variables, which I would not do if binutils followed the gcc coding conventions consistently (see https://gcc.gnu.org/codingconventions.html#Expressions). (sizeof *x) looks a lot better to me, or even (sizeof (*x)) which I've used here. * peXXigen.c (get_contents_sanity_check): New function. (pe_print_idata): Use it here.. (pe_print_edata): ..and here. Free data on error return. (rsrc_parse_entry): Check entry size read from file. (rsrc_parse_entries): Style fixes. (rsrc_process_section): Use bfd_malloc_and_get_section. (_bfd_XXi_final_link_postscript): Likewise.
2023-01-10Move mips_refhi_list to bfd tdataAlan Modra3-18/+31
Similar to commit c799eddb3512, but for mips-ecoff. mips-ecoff is marked obsolete, but we still allow reading of these object files in a number of mips targets. * coff-mips.c (struct mips_hi, mips_refhi_list): Delete. (mips_refhi_reloc, mips_reflo_reloc): Access mips_refhi_list in ecoff_data. * ecoff.c (_bfd_ecoff_close_and_cleanup): New function. * libecoff.h (struct mips_hi): Moved from coff-mips.c. (struct ecoff_tdata): Add mips_refhi_list. (_bfd_ecoff_close_and_cleanup): Declare.
2023-01-10Move bfd_init to bfd.cAlan Modra7-60/+56
init.c contains just one function that doesn't do much. Move it to bfd.c and give it something to do, initialising static state. So far the only initialisation is for bfd.c static variables. The idea behind reinitialising state is to see whether some set of flaky oss-fuzz crashes go away. oss-fuzz stresses binutils in ways that can't occur in reality, feeding multiple testcases into the internals of binutils. So one testcase may affect the result of the next testcase. * init.c: Delete file. Move bfd_init to.. * bfd.c (bfd_init): ..here. Init static variables. * Makefile.am (BFD32_LIBS): Remove init.lo. (BFD32_LIBS_CFILES, BFD_H_FILES): Remove init.c. * doc/local.mk: Remove mention of init.texi and init.c. * Makefile.in: Regenerate. * bfd-in2.h: Regenerate. * po/SRC-POTFILES.in: Regenerate.

2023-01-06Make coff backend data read-onlyAlan Modra6-34/+56
The bfd_coff_backend_data struct should be read-only, the only thing preventing this is that objcopy writes to one of the fields, _bfd_coff_long_section_names. This patch creates a copy of the field in bfd coff_obj_tdata, which makes more sense anyway. When enabling long section names the intent is to do so for a particular bfd, not for all bfds that might happen to be using the target xvec. bfd/ * coffcode.h: Update coff long section name comment.

2022-12-26bfd/dwarf2.c: allow use of DWARF5 directory entry 0Alan Modra1-13/+10
I think the test for table->files[file].dir being non-zero is wrong for DWARF5 where index zero is allowed and is the current directory of the compilation. Most times this will be covered by the use of table->comp_dir (from DW_AT_comp_dir) in concat_filename but the point of putting the current dir in .debug_line was so the section could stand alone without .debug_info. Also, there is no need to check for table->dirs non-NULL, the table->num_dirs test is sufficient. * dwarf2.c (concat_filename): Correct and simplify tests of directory index.

2022-12-23RISC-V: Relax the order checking for the architecture stringNelson Chu1-135/+75
* riscv-toolchain-conventions, PR, https://github.com/riscv-non-isa/riscv-toolchain-conventions/pull/14 Issue, https://github.com/riscv-non-isa/riscv-toolchain-conventions/issues/11 * Refer to the commit afc41ffb, RISC-V: Reorder the prefixed extensions which are out of order. In the past we only allow to reorder the prefixed extensions. But according to the PR 14 in the riscv-toolchain-convention, we can also relax the order checking to allow the whole extensions be written out of orders, including the single standard extensions and the prefixed multi-letter extensions. Just that we still need to follow the following rules as usual, 1. prefixed extensions need to be seperated with `_'. 2. prefixed extensions need complete <major>.<minor> version if set. Please see the details in the march-ok-reorder gas testcase. Passed the riscv-gnu-toolchain regressions. bfd/ * elfxx-riscv.c (enum riscv_prefix_ext_class): Changed RV_ISA_CLASS_UNKNOWN to RV_ISA_CLASS_SINGLE, since everything that does not belong to the multi-keyword will possible be a single extension for the current parser.

2022-12-22PR29925, Memory leak in find_abstract_instanceAlan Modra1-12/+19
The testcase in the PR had a variable with both DW_AT_decl_file and DW_AT_specification, where the DW_AT_specification also specified DW_AT_decl_file. This leads to a memory leak as the file name is malloced and duplicates are not expected. I've also changed find_abstract_instance to not use a temp for "name", because that can result in a change in behaviour from the usual last of duplicate attributes wins. PR 29925 * dwarf2.c (find_abstract_instance): Delete "name" variable. Free *filename_ptr before assigning new file name. (scan_unit_for_symbols): Similarly free func->file and var->file before assigning.

2022-12-21enable-non-contiguous-regions warningsAlan Modra11-52/+19
The warning about discarded sections in elf_link_input_bfd doesn't belong there since the code is dealing with symbols. Multiple symbols in a discarded section will result in multiple identical warnings about the section. Move the warning to a new function in ldlang.c. The patch also tidies the warning quoting of section and file names, consistently using `%pA' and `%pB'. I'm no stickler for one style of section and file name quoting, but they ought to be consistent within a warning, eg. see the first one fixed in ldlang.c, and when a warning is emitted for multiple targets they all ought to use exactly the same format string to reduce translation work. elf64-ppc.c loses the build_one_stub errors since we won't get there before hitting the fatal errors in size_one_stub. bfd/ * elflink.c (elf_link_input_bfd): Don't warn here about discarded sections. * elf32-arm.c (arm_build_one_stub): Use consistent style in --enable-non-contiguous-regions error. * elf32-csky.c (csky_build_one_stub): Likewise. * elf32-hppa.c (hppa_build_one_stub): Likewise. * elf32-m68hc11.c (m68hc11_elf_build_one_stub): Likewise. * elf32-m68hc12.c (m68hc12_elf_build_one_stub): Likewise. * elf32-metag.c (metag_build_one_stub): Likewise. * elf32-nios2.c (nios2_build_one_stub): Likewise. * elfnn-aarch64.c (aarch64_build_one_stub): Likewise. * xcofflink.c (xcoff_build_one_stub): Likewise. * elf64-ppc.c (ppc_size_one_stub): Likewise.

The discard of symbols should be performed whether the warning for the discard is enabled or not.
