2015-10-29Re: Orphan output section with multiple input sectionsAlan Modra1-1/+1
The last patch missed handling the case where the ideal place to put an orphan was after a non-existent output section statement, as can happen when not using the builtin linker scripts. This patch uses the updated flags for that case too, and extends the support to mmo and pe.

2015-08-04ld: Add '--require-defined' command line option.Andrew Burgess1-0/+2
Add a new command line option '--require-defined' to the linker. This option operates identically to the '--undefined' option, except that if the symbol is not defined in the final output file then the linker will exit with an error. When making use of --gc-section, or just when trying to pull in parts of a library, it is not uncommon for a user to use the '--undefined' command line option to specify a symbol that the user then expects to be defined by one of the object files supplied to the link. However, if for any reason the symbol is not satisfied by an object provided to the link the user will be left with an undefined symbol in the output file, instead of a defined symbol. In some cases the above behaviour is what the user wants, in other cases though we can do better. The '--require-defined' option tries to fill this gap. The symbol passed to the '--require-defined' option is treated exactly as if the symbol was passed to '--undefined', however, before the linker exits a check is made that all symbols passed to '--require-defined' are actually defined, if any are not then the link will fail with an error. ld/ChangeLog: * ld.texinfo (Options): Document --require-defined option. * ldlang.c (struct require_defined_symbol): New structure.

2015-02-14PR ld/17973 LTO file symsAlan Modra1-0/+3
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.

2014-01-16Tidy ld use of bfd_section userdata.Alan Modra1-0/+12
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.
