fix test suite regression

This fixes a test suite regession that Yao noticed.
This test checks for some specific "target debug" output
that has changed since the test was written.

2014-08-04  Tom Tromey  <tromey@redhat.com>

	* gdb.base/sss-bp-on-user-bp-2.exp: Match "to_resume", not
	"target_resume".
make "set debug target" take effect immediately

Right now, "set debug target" acts a bit strangely.

Most target APIs only notice that it has changed when the target stack
is changed in some way.  This is because many methods implement the
setting using the special debug target.  However, a few spots do
change their behavior immediately -- any place explicitly checking
"targetdebug".

Some of this peculiar behavior is documented.  However, I think that
it just isn't very useful for it to work this way.  So, this patch
changes "set debug target" to take effect immediately in all cases.
This is done by simply calling update_current_target when the setting
is changed.

This required one small change in the test suite.  Here a test was
expecting the current behavior.

Built and regtested on x86-64 Fedora 20.

2014-08-04  Tom Tromey  <tromey@redhat.com>

	* target.c (set_targetdebug): New function.
	(initialize_targets): Pass set_targetdebug when creating "set
	debug target".

Fix incorrect placement of two Intel gdb/NEWS items

Fix LTO vs. COFF archives

Avoid scan of symbols on objects in coff archives since we don't need
to do anything special with common symbols.  The scan is quite useless,
and breaks LTO due to slim LTO objects not having symbols available
until after the plugin has claimed them.  Instead we can add objects
based on their archive symbol map.

Also, rip out the archive symbol hash table used by the generic
linker.  Using a hash breaks one feature of unix archive linking;
The first object file in an archive defining any given symbol should
be the object extracted to satisfy that symbol.  What's more a hash
isn't much faster except in pathological cases where object file
ordering causes many scans of the archive.  See the comment which I'm
removing from elf_link_add_archive_symbols.

Finally, tidy elflink.c archive handling a little.

	PR 13557
	* linker.c (struct archive_list, struct archive_hash_entry,
	struct archive_hash_table, archive_hash_newfunc,
	archive_hash_table_init, archive_hash_lookup, archive_hash_allocate,
	archive_hash_table_free): Delete.
	(_bfd_generic_link_add_archive_symbols): Add h and name params to
	checkfn.  Rewrite using a straight-forward scan over archive map.
	(generic_link_check_archive_element_no_collect,
	generic_link_check_archive_element_collect,
	generic_link_check_archive_element): Add h and name params.
	* aoutx.h (aout_link_check_archive_element): Likewise.
	* pdp11.c (aout_link_check_archive_element): Likewise.
	* xcofflink.c (xcoff_link_check_archive_element): Likewise.
	* cofflink.c (coff_link_check_archive_element): Likewise.  Don't
	scan symbols, simply add archive element whenever h is undefined.
	(coff_link_check_ar_symbols): Delete.
	* ecoff.c (read_ext_syms_and_strs): Delete.
	(reread_ext_syms_and_strs): Delete.
	(ecoff_link_check_archive_element): Add h and name param.  Don't
	scan symbols, simply add based on h.  Use ecoff_link_add_object_symbols.
	* elflink.c (elf_link_is_defined_archive_symbol): Don't test
	archive_pass.
	(elf_link_add_archive_symbols): Delete "defined" array, merge
	functionality into "included".  Make "included" a char array.  Don't
	set or test archive_pass.
	* libbfd-in.h (_bfd_generic_link_add_archive_symbols): Update.
	* libbfd.h: Regenerate.
Fix load of archive element with common def for -u sym

	* linker.c (generic_link_check_archive_element): Move handling
	of command link -u symbols with a common symbol def to the
	code handling non-common symbols so that archive element symbols
	are loaded.  Use generic_link_add_object_symbols.
Fix PR17226, ld --gc-sections segfaults on sparc-linux

	PR ld/17226
	* elfxx-sparc.c (_bfd_sparc_elf_gc_sweep_hook): Typo fix.
