2023-02-06ppc32 and "LOAD segment with RWX permissions"Alan Modra1-0/+2
When using a bss-plt we'll always trigger the RWX warning, which disturbs gcc test results. On the other hand, there may be reason to want the warning when gcc is configured with --enable-secureplt. So turning off the warning entirely for powerpc might not be the best solution. Instead, we'll turn off the warning whenever a bss-plt is generated, unless the user explicitly asked for the warning. bfd/ * elf32-ppc.c (ppc_elf_select_plt_layout): Set no_warn_rwx_segments on generating a bss plt, unless explicity enabled by the user.

2022-05-26ld: add --package-metadataLuca Boccassi1-0/+2
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.

2021-03-29TRUE/FALSE simplificationAlan Modra1-1/+1
There is really no need to write code like "foo != 0 ? TRUE : FALSE" unless we had stupidly defined FALSE as something other than 0 or TRUE as something other than 1. The simpler "foo != 0" does just as well. Similarly "(condition == TRUE)" or "(condition == FALSE) can be simplified to "(condition)" and "(!condition)" respectively. I'll note that there is reason to use "integer_expression != 0" when assigning a bfd_boolean rather than the simpler "integer_expression", if you expect the variable to have 0 or 1 value. It's probably even a good idea to not rely on implicit conversion if bfd_boolean were _Bool. bfd/ * aoutx.h (aout_link_write_symbols): Don't cast boolean expression to bfd_boolean. * elf32-or1k.c (or1k_set_got_and_rela_sizes): Dont compare booleans against FALSE. * elf32-arc.c (name_for_global_symbol): Don't compare boolean to TRUE.

The symbol string table in the .symtab section is optional and cosmetic. The contents of the .symtab section have no impact on run-time execution. The symbol names in the symbol string table help distinguish addresses at different locations. Add a linker option, -z unique-symbol, to avoid duplicated local symbol names in the symbol string table. This feature was well received by the livepatch maintainers. It not only solves the duplicated local symbol name problem, but also would allow livepatch to more precisely locate duplicate symbols in general for patching. bfd/ PR ld/26391 * elflink.c (elf_final_link_info): Add local_hash_table.

2020-07-22ld: new options --ctf-variables and --ctf-share-typesNick Alcock1-0/+29
libctf recently changed to make it possible to not emit the CTF variables section. Make this the default for ld: the variables section is a simple name -> type mapping, and the names can be quite voluminous. Nothing in the variables section appears in the symbol table, by definition, so GDB cannot make use of them: special-purpose projects that implement their own analogues of symbol table lookup can do so, but they'll need to tell the linker to emit the variables section after all. The new --ctf-variables option does this. The --ctf-share-types option (valid values "share-duplicated" and "share-unconflicted") allow the caller to specify the CTF link mode. Most users will want share-duplicated, since it allows for more convenient debugging: but very large projects composed of many decoupled components may want to use share-unconflicted mode, which places types that appear in only one TU into per-TU dicts. (They may also want to relink the CTF using the ctf_link API and cu-mapping, to make their "components" larger than a single TU. Right now the linker does not expose the CU-mapping machinery. Perhaps it should in future to make this use case easier.) For now, giving the linker the ability to emit share-duplicated CTF lets us add testcases for that mode to the testsuite. ld/ * ldlex.h (option_values) <OPTION_CTF_VARIABLES, OPTION_NO_CTF_VARIABLES, OPTION_CTF_SHARE_TYPES>: New. * ld.h (ld_config_type) <ctf_variables, ctf_share_duplicated>: New fields. * ldlang.c (lang_merge_ctf): Use them. * lexsup.c (ld_options): Add ctf-variables, no-ctf-variables, ctf-share-types.

2020-06-06ld -plugin options when plugins are disabledAlan Modra1-0/+5
This patch makes ld accept and ignore -plugin options when configured with --disable-plugins. The idea is to allow using a linker built without plugin support with a gcc built with plugin support. Quite obviously such a combination won't work if using LTO, but gcc has a habit of passing a bunch of -plugin and -plugin-opt arguments to ld even when not generating or linking LTO objects. Why do I want to do this? Well, it lets me and other binutils developers answer the question as to whether plugin support breaks binutils in some areas.
