The search order used in this patch breaks global symbol lookups
for certain symbols when copy-relocation is used. A slightly different
search order will be implemented later.
gdb/ChangeLog:
Revert the following patch:
* findvar.c (default_read_var_value): For LOC_UNRESOLVED symbols,
try locating the symbol in the symbol's own objfile first, before
extending the search to all objfiles.
* symtab.c (lookup_symbol_aux_objfile): New function, extracted
out of lookup_symbol_aux_symtabs.
(lookup_symbol_aux_symtabs): Add new parameter "exclude_objfile".
Replace extracted-out code by call to lookup_symbol_aux_objfile.
Do not search EXCLUDE_OBJFILE.
(lookup_static_symbol_aux): Update call to lookup_symbol_aux_symtabs.
(lookup_symbol_global): Search for matches in the block's objfile
first, before searching all other objfiles.
This patch adjusts the testing strategy used in a couple of testcases
where we are trying to print the value of a global variable defined
at multiple locations. The problem is that the actual value depends
on the platform. So instead of hard-coding the expected value in
the testcase script, we use local variables (in the inferior) holding
the correct value, and we compare the global variable's value with
the local variable's value.
gdb/testsuite/ChangeLog:
* gdb.base/ctxobj-f.c (GET_VERSION): Introduce local variable
and add comment.
* gdb.base/ctxobj-m.c (main): Rewrite, and add comment.
* gdb.base/ctxobj.exp: Insert breakpoint in ctxobj-f.c using
"STOP" marker. Adjust testing strategy to make it work on
all targets.
* gdb.base/print-file-var-main.c (main): Rewrite using local
variables and adjust get_version_2's return value check.
Add small comment.
* gdb.base/print-file-var.exp: Insert breakpoint using "STOP"
marker. Adjust testing strategy to make it work on all targets.
With an Ada program, trying to break on a specific Ada task, but
with the wrong capitalization of the `task' keyword, we currently
get only pieces of the "garbage" that caused the error:
(gdb) b *rendez_vous'address TASK 2
Garbage 2 at end of command
Pushing this a little further:
(gdb) b *rendez_vous'address TASK Task TaSK 2
Garbage 2 at end of command
Another interesting failure mode:
(gdb) b *rendez_vous'address TASK if
Argument required (expression to compute).
The parser skipped `TASK', then found the `if' keyword, and thus
started looking for a condition.
This patch fixes the problem by aborting the parsing as soon as
an invalid keyword is found. This makes it consistent with the
case where the REST parameter is passed as NULL (where an error
is raised immediately after seeing the first invalid keyword).
It also introduces a new testcase that reproduces all above scenarios.
gdb/ChangeLog:
* breakpoint.c (find_condition_and_thread): Stop parsing
as soon as the first invalid keyword is found.
gdb/testsuite/ChangeLog:
* gdb.ada/bad-task-bp-keyword: New testcase.
Normally, all files should have a copyright header, but gdb/CONTRIBUTE
currently doesn't, and it adding one at the top of the file would
probably be more pollution than information. So don't require
a copyright header for now.
gdb/ChangeLog:
* copyright.py (EXCLUDE_LIST): Add 'gdb/CONTRIBUTE' to list.
There is an extra coma after the copyright year which tricks
gnulib's update-copyright script.
gdb/stubs/ChangeLog:
* ia64vms-stub.c: Adjust copyright header to follow convention
expected by gnulib's update-copyright script.
The location where we store the gnulib import has changed.
This patch updates accordingly the path to gnulib's update-copyright
script.
gdb/ChangeLog:
* copyright.py (update_files, main): Fix path to update-copyright
script.

* copyright.py (MULTIPLE_COPYRIGHT_HEADERS): New constant.
(main): Add MULTIPLE_COPYRIGHT_HEADERS to the list of files
