2017-06-06ld: Allow section groups to be resolved as part of a relocatable linkAndrew Burgess1-1/+3
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. (bfd_elf_set_group_contents): Replace use of abort with an assert. (assign_section_numbers): Use resolve_section_groups flag instead of relocatable link type. (_bfd_elf_init_private_section_data): Use resolve_section_groups flag instead of checking the final_link flag for part of the checks in here. Fix white space as a result. * elflink.c (elf_link_input_bfd): Use resolve_section_groups flag instead of relocatable link type.

2015-01-28Allow symbols in MEMORY region specificationSenthil Kumar Selvaraj1-2/+2
This patch fixes PR 4643 by allowing symbols in the LENGTH and ORIGIN fields of MEMORY regions. Previously, only constants and constant expressions are allowed. For the AVR target, this helps define memory constraints more accurately (per device), without having to create a ton of device specific linker scripts. ld/ PR 4643 * ldexp.c (fold_name): Fold LENGTH only after lang_first_phase_enum. * ldgram.y (memory_spec): Don't evaluate ORIGIN and LENGTH rightaway. * ldlang.h (struct memory_region_struct): Add origin_exp and length_exp fields. * ldlang.c (lang_do_memory_regions): New.

* ldlex.l (INPUTLIST): New start condition. (comment pattern, ",", "(", ")", "AS_NEEDED") ({FILENAMECHAR1}{FILENAMECHAR}*, "-l"{FILENAMECHAR}+) (quoted string pattern, whitespace pattern): Add INPUTLIST to valid start conditions. (<INPUTLIST>"="{FILENAMECHAR1}{FILENAMECHAR}*): New NAME rule. (ldlex_inputlist): New start-condition-setter function. * ldgram.y (input_list1): Rename from input_list. All recursive use changed. (input_list): New wrapper rule for input_list1, setting INPUTLIST lexer state for the duration of parsing input_list1. All this to say INPUT(=/path/to/file) and not be forced to use INPUT("=/path/to/file") whenever there's a need to force a sysroot- prefix. Still, IMHO it seems better to make use of a previously invalid syntax and not only change the meaning of quoted =-prefixed paths (though arguably that's not very useful before this patchset). This got a little bit hairier than I'd expected: I had to add a new lexer state (aka. start condition) to avoid a first "=" being lexed as the token "=", despite that not making sense in constructs expecting file-names in the first place. (The grammar doesn't allow for expressions in any part of those lists.) I guess I *could* have made it work using that token anyway, but I didn't like the idea that you would be able to separate the "=" from the rest of the file-name with whitespace.
