2022-11-28Special case more simple patternsMichael Matz1-1/+2
fnmatch is slow, so avoiding it in more cases is good. This implements a more generic version of match_simple_wild which needs some pre-processing of patterns. In particular it supports patterns of the form PREFIX*SUFFIX (where all parts are optional), i.e. a super set of what's handled now. Most section matchers of this form and hence don't need any calls to fnmatch anymore. We retain the implementation of match_simple_wild for the filename matchers (they aren't called often enough to matter).

2022-02-13PR28824, relro security issues, x86 keep COMMONPAGESIZE relroAlan Modra1-0/+4
x86 treats MAXPAGESIZE as a memory optimisation parameter, actual hardware paging is always COMMPAGESIZE of 4k. Use COMMONPAGESIZE for the end of the relro segment alignment. The previous patch regresses pr18176, increasing the testcase file size from 322208 to 2099872 bytes. Fixing this on x86 will require introducing a gap after the end of the relro segment (of up to relropagesize-1 bytes).

2020-07-22ld: new options --ctf-variables and --ctf-share-typesNick Alcock1-0/+8
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.

2017-11-07ngettext supportAlan Modra1-2/+8
binutils has lacked proper pluralization of output messages for a long time, for example, readelf will display information about a section that "contains 1 entries" or "There are 1 section headers". Fixing this properly requires us to use ngettext, because other languages have different rules to English. This patch defines macros for ngettext and friends to handle builds with --disable-nls, and tidies the existing nls support. I've redefined gettext rather than just defining "_" as dgettext in bfd and opcodes in case someone wants to use gettext there (which might conceivably happen with generated code). bfd/ * sysdep.h: Formatting, comment fixes.

2017-08-06Treat common symbol as undefined for --no-define-commonH.J. Lu1-3/+0
When --no-define-common is used to build shared library, treat common symbol as undefined so that common symbols that are referenced from a shared library to be assigned addresses only in the main program. This eliminates the unused duplicate space in the shared library, and also prevents any possible confusion over resolving to the wrong duplicate when there are many dynamic modules with specialized search paths for runtime symbol resolution. --no-define-common is only allowed when building a shared library. bfd/ PR ld/21903: * elflink.c (elf_link_add_object_symbols): Treat common symbol as undefined for --no-define-common. include/ PR ld/21903: * bfdlink.h (bfd_link_info): Add inhibit_common_definition. ld/ PR ld/21903: * ld.h (command_line): Remove inhibit_common_definition. * ldgram.y: Replace command_line.inhibit_common_definition with link_info.inhibit_common_definition. * ldlang.c (lang_common): Likewise. * lexsup.c (parse_args): Likewise. * ldmain.c (main): Only allow --no-define-common with -shared. * testsuite/ld-elf/pr21903.s: New file. * testsuite/ld-elf/pr21903a.d: Likewise. * testsuite/ld-elf/pr21903b.d: Likewise. * testsuite/ld-elf/pr21903c.d: Likewise. * testsuite/ld-elf/pr21903d.d: Likewise. * testsuite/ld-elf/pr21903e.d: Likewise.

2017-06-06ld: Allow section groups to be resolved as part of a relocatable linkAndrew Burgess1-0/+5
This commit adds a new linker feature: the ability to resolve section groups as part of a relocatable link. Currently section groups are automatically resolved when performing a final link, and are carried through when performing a relocatable link. By carried through this means that one copy of each section group (from all the copies that might be found in all the input files) is placed into the output file. Sections that are part of a section group will not match input section specifiers within a linker script and are forcibly kept as separate sections. There is a slight resemblance between section groups and common section. Like section groups, common sections are carried through when performing a relocatable link, and resolved (allocated actual space) only at final link time. However, with common sections there is an ability to force the linker to allocate space for the common sections when performing a relocatable link, there's currently no such ability for section groups. This commit adds such a mechanism. This new facility can be accessed in two ways, first there's a command line switch --force-group-allocation, second, there's a new linker script command FORCE_GROUP_ALLOCATION. If one of these is used when performing a relocatable link then the linker will resolve the section groups as though it were performing a final link, the section group will be deleted, and the members of the group will be placed like normal input sections. If there are multiple copies of the group (from multiple input files) then only one copy of the group members will be placed, the duplicate copies will be discarded. Unlike common sections that have the --no-define-common command line flag, and INHIBIT_COMMON_ALLOCATION linker script command there is no way to prevent group resolution during a final link, this is because the ELF gABI specifically prohibits the presence of SHT_GROUP sections in a fully linked executable. However, the code as written should make adding such a feature trivial, setting the new resolve_section_groups flag to false during a final link should work as you'd expect. bfd/ChangeLog: * elf.c (_bfd_elf_make_section_from_shdr): Don't initially mark SEC_GROUP sections as SEC_EXCLUDE.

2014-01-16Tidy ld use of bfd_section userdata.Alan Modra1-12/+0
A long time ago ld made use of userdata to tie an output section to its lang_input_statement_struct object file. Some time later Joern made map file printing of symbols at lot faster, using userdata on input sections. That complicated allocation of userdata, and when the output section use disappeared a year later, the code wasn't properly cleaned up. This patch does that cleanup, and also tidies the symbol printing code to not allocate userdata where it won't be needed. We don't print symbols defined in the absolute section or in output sections. * ld.h (fat_section_userdata_type, get_userdata): Move to.. * ldlang.h (input_section_userdata_type, get_userdata): ..here. * ldlang.c (init_map_userdata): Delete. Fold into.. (sort_def_symbol): ..here. Don't attach input section userdata to output sections or global bfd sections. (lang_map): Don't pre-allocate input section userdata.
