2022-06-08Revert reloc howto nitsAlan Modra30-291/+291
The "HOWTO size encoding" patch put 1 as the HOWTO size arg for numerous howtos that are unused, describe dynamic relocs, are markers, or otherwise are special purpose reloc howtos that don't care about the size. The idea was to ensure no howto changed by inspecting object files. Revert those changes, making them zero size. * coff-alpha.c: Give special purpose reloc howtos a size of zero. * coff-mcore.c, * elf-hppa.h, * elf-m10300.c, * elf32-arm.c, * elf32-csky.c, * elf32-m32c.c, * elf32-m68k.c, * elf32-mep.c, * elf32-mips.c, * elf32-ppc.c, * elf32-rx.c, * elf32-s390.c, * elf32-spu.c, * elf32-tic6x.c, * elf32-tilepro.c, *elf32-vax.c, * elf32-xtensa.c, * elf64-alpha.c, * elf64-mips.c, * elf64-mmix.c, * elf64-ppc.c, * elf64-s390.c, * elfn32-mips.c, * elfxx-loongarch.c, * elfxx-riscv.c, * elfxx-sparc.c, * elfxx-tilegx.c, * som.c, * vms-alpha.c: Likewise.
2022-06-08HOWTO size encodingAlan Modra104-4092/+4058
This changes the HOWTO macro to encode the howto.size field from a value given in bytes. This of course requires editing all target uses of HOWTO, a major pain, but makes it a little nicer to specify new target HOWTOs. Object files before/after this patch are unchanged in .data and .rodata. bfd/ * reloc.c (HOWTO_RSIZE): Encode size in bytes.

Similarly for the elf mips support. * elf32-mips.c (mips_elf_final_gp): Don't segfault on symbols in any of the bfd_is_const_section sections. * elf64-mips.c (mips_elf64_final_gp): Likewise. * elfn32-mips.c (mips_elf_final_gp): Likewise.
2022-06-03asan: mips_gprel_reloc segfaultAlan Modra1-3/+2
Not just the undefined section has a NULL owner, the absolute section has too. Which means we can't find output_bfd for __gp. Also, may as well test directly for output_bfd == NULL. * coff-mips.c (mips_gprel_reloc): Don't segfault on any of bfd_is_const_section sections.

2022-06-02asan: NULL deref in scan_unit_for_symbolsAlan Modra1-24/+23
Since commit b43771b045 it has been possible to look up addresses that match a unit with errors, since ranges are added to a trie while the unit is being parsed. On error, parse_comp_unit leaves first_child_die_ptr NULL which results in a NULL info_ptr being passed to scan_unit_for_symbols. Fix this by setting unit->error. Also wrap some overlong lines, and fix some formatting errors. * dwarf2.c: Formatting. (parse_comp_unit): Set unit->error on err_exit path.

We can't use libiberty.a in chew. libiberty is a host library, chew a build program.

The zhinx extension is a sub-extension in zfinx, corresponding to zfh extension but use GPRs instead of FPRs.

2022-05-27Replace bfd_hostptr_t with uintptr_tAlan Modra11-60/+38
bfd_hostptr_t is defined as a type large enough to hold either a long or a pointer. It mostly appears in the coff backend code in casts. include/coff/internal.h struct internal_syment and union internal_auxent have the only uses in data structures, where comparison with include/coff/external.h and other code reveals that the type only needs to be large enough for a 32-bit integer or a pointer. That should mean replacing with uintptr_t is OK.
2022-05-27Remove much of BFD_HOST configuryAlan Modra6-166/+16
This patch removes the definition of bfd_uint64_t and bfd_int64_t as well as most BFD_HOST_* which are now unused.
2022-05-27Remove use of bfd_uint64_t and similarAlan Modra24-210/+156
Requiring C99 means that uses of bfd_uint64_t can be replaced with uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_* and tidies a few places that print 64-bit values.

2022-05-27cris: bfd: Correct default to no execstackHans-Peter Nilsson1-0/+2
In the now-historical CRIS glibc port, the default stack permission was no-exec as in "#define DEFAULT_STACK_PERMS (PF_R|PF_W)", and the gcc port only emits the executable-stack marker when needed; when emitting code needing it. In other words, the binutils setting mismatches. It doesn't matter much, except being confusing and defaulting to "off" is more sane. ld: * testsuite/ld-elf/elf.exp (target_defaults_to_execstack): Switch to 0 for cris*-*-*. bfd: * elf32-cris.c (elf_backend_default_execstack): Define to 0.

Generate a .note.package FDO package metadata ELF note, following the spec: https://systemd.io/ELF_PACKAGE_METADATA/ If the jansson library is available at build time (and it is explicitly enabled), link ld to it, and use it to validate that the input is correct JSON, to avoid writing garbage to the file. The configure option --enable-jansson has to be used to explicitly enable it (error out when not found). This allows bootstrappers (or others who are not interested) to seamlessly skip it without issues.
