The current hard coded limit of open files in bfd/cache.c is 10. This
is pretty low these days. Binaries are often linked against much more
than 10 files (and sometimes against more than 100 shared libraries).
When debugging with GDB some files are opened and closed multiple
times because of this low limit. If possible make the BFD cache file
limit depend on the actual open file limit of the process so more BFD
files can be open at the same time.
* cache.c (BFD_CACHE_MAX_OPEN): Remove define.
(max_open_files): New static int initialized to zero.
(bfd_cache_max_open): New static function to set and return
max_open_files.
(bfd_cache_init): Use bfd_cache_max_open.
(bfd_open_file): Likewise.
* configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
(AC_CHECK_FUNCS): Add getrlimit.
* configure: Regenerated.
* config.in: Likewise.
* sysdep.h: Check and include sys/resource.h for getrlimit.

This is because the code in this directory is used to build a library which
|
|
will be linked with code in other directories to form programs. We want to
|
|
maintain a seperate translation file for this directory however, rather
|
|
than being forced to merge it with that of any program linked to libbfd.
|
|
This is a library, so it cannot depend on the catalog currently loaded.
|
|
|
|
In order to do this, we have to make sure that when we extract messages we
|
|
use the OPCODES domain rather than the domain of the program that included
|
|
the bfd library, (eg OBJDUMP). Hence we use dgettext (PACKAGE, String)
|
|
and define PACKAGE to be 'bfd'. (See the code in configure). */
