2016-11-04ld: Allow EXCLUDE_FILE to be used outside of the section listAndrew Burgess1-0/+1
Currently the EXCLUDE_FILE linker script construct can only be used within the input section list, and applied only to the section pattern immediately following the EXCLUDE_FILE. For example: *.o (EXCLUDE_FILE (a.o) .text .rodata) In this case all sections matching '.text' are included from all files matching '*.o' but not from the file 'a.o'. All sections matching '.rodata' are also included from all files matching '*.o' (incluing from 'a.o'). If the user wants to restrict the inclusion of section '.rodata' so that this too is not taken from the file 'a.o' then the above example must be extended like this: *.o (EXCLUDE_FILE (a.o) .text EXCLUDE_FILE (a.o) .rodata) However, due to the internal grammar of the linker script language the snippet 'EXCLUDE_FILE (a.o) .text' is parsed by a pattern called 'wildcard_spec'. The same 'wildcard_spec' pattern is also used to parse the input file name snippet '*.o' in the above examples. As a result of this pattern reuse within the linker script grammar then the following is also a valid linker script construct: EXCLUDE_FILE (a.o) *.o (.text .rodata) However, though the linker accepts this without complaint the EXCLUDE_FILE part is silently ignored and has no effect. This commit takes this last example and makes it a useful, valid, construct. The last example now means to include sections '.text' and '.rodata' from all files matching '*.o' except for the file 'a.o'. If the list of input sections is long, and the user knows that the file exclusion applies across the list then the second form might be a clearer alternative to replicating the EXCLUDE_FILE construct. I've added a set of tests for EXCLUDE_FILE to the linker, including tests for the new functionality. ld/ChangeLog: * ldlang.h (struct lang_wild_statement_struct): Add exclude_name_list field. * ldlang.c (walk_wild_file_in_exclude_list): New function.

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.
