* ld.h (args_type): Add field rpath.
* lexsup.c (S_ISDIR): Define if not already defined.
(parse_args): Add support for -rpath. If -R is used to name a
directory, treat it as -rpath for Solaris compatibility.
* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
Pass command_line.rpath to bfd_elf32_size_dynamic_sections.
* ldmain.c (main): Initialize command_line.rpath to NULL.
* ld.texinfo: Document -rpath option.

The @var{archives} should be a list of archive files. They may be
|
||||
either explicit file names, or @samp{-l} options.
|
||||
|
||||
The specified archives are searched repeatedly until no new undefined
|
||||
references are created. Normally, an archive is searched only once in
|
||||
the order that it is specified on the command line. If a symbol in that
|
||||
archive is needed to resolve an undefined symbol referred to by an
|
||||
object in an archive that appears later on the command line, the linker
|
||||
would not be able to resolve that reference. By grouping the archives,
|
||||
they all be searched repeatedly until all possible references are
|
||||
resolved.
|
||||
|
||||
Using this option has a significant performance cost. It is best to use
|
||||
it only when there are unavoidable circular references between two or
|
||||
more archives.
