2019-09-19bfd_section_* macrosAlan Modra1-2/+2
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

2018-12-28PR24015, glibc-2.28 on little-endian mips32 brokenAlan Modra1-1/+1
Commit 2bf2bf23da exposed a bug on targets that create common sections other than the standard ELF SHN_COMMON. If these are output by ld -r, then their type becomes SHT_PROGBITS unless the target handles them specially (eg. by elf_backend_special_sections), and if they are merged into .bss/.sbss by ld -r then that section becomes SHT_PROGBITS. Worse, if they are output by ld -r, then their size is increased by bfd_generic_define_common_symbol during final link, which leads to bogus file contents being copied to output. For mips, it seems to me that the .scommon section should not be output for ld -r, but I haven't made that change in this patch.

2018-07-17LD: Export relative-from-absolute symbol marking to BFDMaciej W. Rozycki1-1/+14
It is usually possible to tell absolute and ordinary symbols apart in BFD throughout the link, by checking whether the section that owns the symbol is absolute or not. That however does not work for ordinary symbols defined in a linker script outside an output section statement. Initially such symbols are entered into to the link hash as absolute symbols, owned by the absolute section. A flag is set in the internal linker expression defining such symbols to tell the linker to convert them to section-relative ones in the final phase of the link. That flag is however not accessible to BFD linker code, including BFD target code in particular. Add a flag to the link hash then to copy the information held in the linker expression. Define a macro, `bfd_is_abs_symbol', for BFD code to use where determining whether a symbol is absolute or ordinary is required before the final link phase. This macro will correctly identify the special `__ehdr_start' symbol as ordinary throughout link, for example, even though early on it will be assigned to the absolute section. Of course this does not let BFD code identify what the symbol's ultimate section will be before the final link phase has converted this symbol (in `update_definedness'). include/ * bfdlink.h (bfd_link_hash_entry): Add `rel_from_abs' member. bfd/ * linker.c (bfd_is_abs_symbol): New macro. * bfd-in2.h: Regenerate. ld/ * ldexp.c (exp_fold_tree_1) <etree_assign, etree_provide> <etree_provided>: Copy expression's `rel_from_abs' flag to the link hash.

2018-02-16Remove bfd stub function casts.Alan Modra1-0/+101
This patch defines a bunch of new functions to use in the BFD target structs rather than casting bfd_false or bfd_true and similar stub functions. I've also renamed the stub functions to reflect their parameters and put "error" in the name if they set bfd_error. The latter change is important since there were quite a few uses of bfd_false where setting bfd_error was inappropriate, for example in elf_backend_allow_non_load_phdr and is_target_special_symbol. * libbfd.c (_bfd_bool_bfd_false_error): Rename from bfd_false.

This patch processes linker script assignment statements before ld opens DT_NEEDED libraries, in order to define symbols like __bss_start that might also be defined by a library, falsely triggering an error about "DSO missing from command line". The initial value won't be correct when assigning a symbol from dot, and I make no attempt to handle all expressions. For example, an assignment like "_start_foo = ADDR (.foo)" isn't valid until sections are laid out, so won't define _start_foo early. What's here should be enough for most common scripts, and hopefully won't perturb fragile scripts. bfd/ PR 22471 * elflink.c (_bfd_elf_merge_symbol): Allow weak symbols to override early passes over linker script symbols. * linker.c (_bfd_generic_link_add_one_symbol): Allow symbols to override early passes over linker script symbols.

2017-06-16Rewrite __start and __stop symbol handlingAlan Modra1-0/+37
This arranges for __start and __stop symbols to be defined before garbage collection, for all target formats. That should allow the COFF and PE --gc-sections to keep a singleton orphan input section, a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF treatment of keeping all input sections associated with a __start or __stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained. .startof. and .sizeof. symbols are deliberately not defined before garbage collection, so these won't affect garbage collection of sections. The patch also ensures __start, __stop, .startof. and .sizeof. symbols are defined before target size_dynamic_sections is called, albeit with a preliminary value, so that target code doesn't need to cope with a symbol changing from undefined at size_dynamic_sections to defined at relocate_section. Also, a number of problems with the testcases have been fixed.

dynamic_ref_after_ir_def is a little odd compared to other symbol flags in that as the name suggests, it is set only for certain references after a definition.

2016-05-28Return void from linker callbacksAlan Modra1-43/+28
The ldmain.c implementation of these linker callback functions always return true, so any code handling a false return is dead. What's more, some of the bfd backends abort if ever a false return is seen, and there seems to be some confusion in gdb's compile-object-load.c. The return value was never meant to be "oh yes, a multiple_definition error occurred", but rather "out of memory or other catastrophic failure". This patch removes the status return on the callbacks that always return true. I kept the return status for "notice" because that one does happen to need to return "out of memory". include/ * bfdlink.h (struct bfd_link_callbacks): Update comments.

2015-02-14PR ld/17973 LTO file symsAlan Modra1-1/+1
LTO output objects have an STT_FILE symbol using the name of the file, a temporary file. This results in executables that can't be exactly reproduced, so the file name needs to be dropped. We don't want to lose all file symbols when linking a mix of lto and non-lto objects as a file symbol can be used to figure which source file generated a given local symbol. So lto output objects need to be marked. I chose to mark lto output objects with a new bfd flag. This flag is also used to fix a bug in the link-once handling; An object being loaded after "loading_lto_outputs" is set might be one extracted from an archive to satisfy new references from lto objects, not an lto object itself. The new flag is copied from archive to elements, and the same done for no_export. This fixes a bug in that --exclude-libs doesn't work with thin archives. I'm not completely happy with this part of the patch and may revist this to avoid the hack in _bfd_look_for_bfd_in_cache.

2015-01-19Fallout from recent bfd_reloc_outofrange changesAlan Modra1-1/+1
Commit ec93045b and cd21f5da introduced a large number of tic4x and tic54x regressions, due to the new checks being wrong for targets with octets_per_byte != 1. To fix that I introduced a new bfd_get_section_limit_octets and performed the check on octets rather than byte adresses, reducing the number of bfd_octets_per_byte calls. bfd_octets_per_byte is rather expensive.. I then wondered why the same bfd_reloc_outofrange check added to bfd_perform_relocation wasn't also added to bfd_install_relocation. The two functions are virtually identical and ought to remain that way. However, adding the same check to bfd_install_relocation resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF targets, including x64_64-linux. The reason being that eh-group.o has NONE relocs at the end of a section, and most targets give NONE relocs a non-zero size. So if we are to keep the new outofrange check it appears that NONE relocs must have a zero size. * bfd-in.h (bfd_get_section_limit_octets): New define, extracted from..

2014-08-12Change ld "notice" interface for better handling of indirect symbolsAlan Modra1-38/+44
The main aim of this change was to have non_ir_ref set correctly on new indirect symbols.

WARN has always been able to be handled by the CWARN case (WARN was used when the previous symbols was undef, undefweak or common and thus must be on the undefs list, so the CWARN test passes).
