2021-07-30bfd: ensure that symbols targeted by DWARF relocations are kept in XCOFFClément Chigot1-79/+106
This patch improves XCOFF garbage collector pass, in order to keep symbols being referenced only by special sections like DWARF sections. bfd/ * xcofflink.c (xcoff_mark): Replace SEC_MARK by gc_mark. Look through relocations even if xcoff_section_data is NULL. (xcoff_sweep): Check if any sections of a file is kept before adding its special sections. Call xcoff_mark for special sessions being kept instead of just marking them. (SEC_MARK): Remove (xcoff_mark_symbol): Replace SEC_MARK by gc_mark. (xcoff_keep_symbol_p): Likewise. (bfd_xcoff_size_dynamic_sections): Likewise. (xcoff_find_tc0): Likewise.
2021-07-30bfd: avoid a crash when debug_section isn't created in XCOFFClément Chigot1-1/+2

2021-07-30reloc_upper_bound size calculationsAlan Modra5-5/+5
Section reloc_count is an unsigned int. Adding one for a NULL terminator to an array of arelent pointers can wrap the count to zero. Avoid that by doing the addition as longs. * coffgen.c (coff_get_reloc_upper_bound): Don't overflow unsigned int expression. * elf.c (_bfd_elf_get_reloc_upper_bound): Likewise. * elf64-sparc.c (elf64_sparc_get_reloc_upper_bound): Likewise. * mach-o.c (bfd_mach_o_get_reloc_upper_bound): Likewise. * vms-alpha.c (alpha_vms_get_reloc_upper_bound): Likewise.

From microsoft docs: It is an error if IMAGE_SCN_LNK_NRELOC_OVFL is set and there are fewer than 0xffff relocations in the section. * coffcode.h (coff_set_alignment_hook): Sanity check overflow reloc count.

2021-07-29gas: improve C_BSTAT and C_STSYM symbols handling on XCOFFClément Chigot2-5/+9
A C_BSTAT debug symbol specifies the beginning of a static block. Its n_value is the index of the csect containing static symbols. A C_STSYM debug symbol represents the stabstring of a statically allocated symbol. Its n_value is the offset in the csect pointed by the containing C_BSTAT. These two special n_value were not correctly handled both when generating object files with gas or when reading them with objdump. This patch tries to improve that and, above all, to allow gas-generated object files with such symbols to be accepted by AIX ld. bfd/ * coff-bfd.c (bfd_coff_get_syment): Adjust n_value of symbols having fix_value = 1 in order to be an index and not a memory offset. * coffgen.c (coff_get_symbol_info): Likewize. (coff_print_symbol): Likewize. gas/ * config/tc-ppc.c (ppc_frob_label): Don't change within if already set. (ppc_stabx): Remove workaround changing exp.X_add_symbol's within. * config/tc-ppc.h (struct ppc_tc_sy): Update comments. * symbols.c (resolve_symbol_value): Remove symbol update when final_val is 0 and it's an AIX debug symbol. * testsuite/gas/ppc/aix.exp: Add new tests. * testsuite/gas/ppc/xcoff-stsym-32.d: New test. * testsuite/gas/ppc/xcoff-stsym-64.d: New test. * testsuite/gas/ppc/xcoff-stsym.s: New test.

Close the file descriptor if there is no archive plugin file descriptor to avoid running out of file descriptors on thin archives with many archive members. bfd/ PR ld/28138 * plugin.c (bfd_plugin_close_file_descriptor): Close the file descriptor there is no archive plugin file descriptor. ld/ PR ld/28138 * testsuite/ld-plugin/lto.exp: Run ld/28138 tests. * testsuite/ld-plugin/pr28138.c: New file. * testsuite/ld-plugin/pr28138-1.c: Likewise. * testsuite/ld-plugin/pr28138-2.c: Likewise. * testsuite/ld-plugin/pr28138-3.c: Likewise. * testsuite/ld-plugin/pr28138-4.c: Likewise. * testsuite/ld-plugin/pr28138-5.c: Likewise. * testsuite/ld-plugin/pr28138-6.c: Likewise. * testsuite/ld-plugin/pr28138-7.c: Likewise.

2021-07-21Remove `netbsdpe` supportJohn Ericson1-4/+0
netbsdpe was deprecated in c2ce831330e10dab4703094491f80b6b9a5c2289. Since then, a release has passed (2.37), and it was marked obselete in 5c9cbf07f3f972ecffe13d858010b3179df17b32. Unless I am mistaken, that means we can now remove support altogether. All branches in the "active" code are remove, and the target is additionally marked as obsolete next to the other removed ones for libbfd and gdb. Per [1] from the NetBSD toolchain list, PE/COFF support was removed a decade ago. Furthermore, the sole mention of this target in the binutils commit history was in 2002. Together, I'm led to believe this target hasn't seen much attention in quite a while. [1]: https://mail-index.netbsd.org/tech-toolchain/2021/06/16/msg003996.html bfd/ * config.bfd: Remove netbsdpe entry. binutils/ * configure.ac: Remove netbsdpe entry. * testsuite/lib/binutils-common.exp (is_pecoff_format): Likewise. * configure: Regenerate. gas/ * configure.tgt: Remove netbsdpe entry. gdb/ * configure.tgt: Add netbsdpe to removed targets. ld/ * configure.tgt: Remove netbsdpe entry. * testsuite/ld-bootstrap/bootstrap.exp: Likewise.

2021-07-20RISC-V: Minor updates for architecture parser.Nelson Chu1-94/+82
* Two add subset functions is redundant. Keep the riscv_add_implicit_subset, and renamed it to riscv_add_subset. Besides, if the subset is added in order, then we just add it at the tail of the subset list. * Removed the "-march:" prefix from the error messages. Since not only the -march= option will use the parser, but also the architecture elf attributes, the default architecture setting and linker will use the same parser. * Use a function, riscv_parse_check_conflicts, to check the conflicts of extensions, including the rv64e and rv32q. The rv32emc-elf/rv32i-elf/rv32gc-linux/rv64gc-elf/rv64gc-linux regressions are tested and passed. bfd/ * elfxx-riscv.c (riscv_lookup_subset): Check the subset tail list first.
