* Windows-specific iterate_over_objfiles_in_search_orderJoel Brobecker2012-06-055-0/+69
| | | | | | | | | | | | | | | | | | This patch sets the windows target to use their own version of the iterate_over_objfiles_in_search_order gdbarch method, in order to make global symbol searches sensitive to the current objfile. gdb/ChangeLog: * windows-tdep.h (windows_iterate_over_objfiles_in_search_order): Add declaration. * windows-tdep.c: #include "objfiles.h". (windows_iterate_over_objfiles_in_search_order): New function. * amd64-windows-tdep.c (amd64_windows_init_abi): Set iterate_over_objfiles_in_search_order gdbarch method to windows_iterate_over_objfiles_in_search_order. * i386-cygwin-tdep.c (i386_cygwin_init_abi): Likewise.
* New "iterate_over_objfiles_in_search_order" gdbarch method.Joel Brobecker2012-06-058-34/+253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the "iterate_over_objfiles_in_search_order" gdbarch method, as well as its default implementation, and converts the areas where it will matter to using this gdbarch method. The default method implementation is the only one installed, and the changes should have no functional impact in terms of behavior. This only paves the way for the architectures that will need their own version. gdb/ChangeLog: * gdbarch.sh: Add generation of "iterate_over_objfiles_in_search_order_cb_ftype" typedef in gdbarch.h. Add include of "objfiles.h" in gdbarch.c. (iterate_over_objfiles_in_search_order): New gdbarch method. * gdbarch.h, gdbarch.c: Regenerate. * objfiles.h (default_iterate_over_objfiles_in_search_order): Add declaration. * objfiles.c (default_iterate_over_objfiles_in_search_order): New function. * symtab.c (lookup_symbol_aux_objfile): New function, extracted out of lookup_symbol_aux_symtabs. (lookup_symbol_aux_symtabs): Replace extracted-out code by call to lookup_symbol_aux_objfile. (struct global_sym_lookup_data): New type. (lookup_symbol_global_iterator_cb): New function. (lookup_symbol_global): Search for symbol using gdbarch_iterate_over_objfiles_in_search_order and lookup_symbol_global_iterator_cb. * findvar.c (struct minsym_lookup_data): New type. (minsym_lookup_iterator_cb): New function. (default_read_var_value) [case LOC_UNRESOLVED]: Resolve the symbol's address via gdbarch_iterate_over_objfiles_in_search_order and minsym_lookup_iterator_cb.
* Revert "Search global symbols from the expression's block objfile first."Joel Brobecker2012-06-053-83/+47
| | | | | | | | | | | | | | | | | | | | | 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.
* Make ctxobj.exp and print-file-var.exp work on all platforms.Joel Brobecker2012-06-056-26/+103
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* stop parsing breakpoint command if invalid keyword foundJoel Brobecker2012-06-055-1/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* copyright.py: Add gdb/CONTRIBUTE to EXCLUDE_LIST.Joel Brobecker2012-06-052-0/+5
| | | | | | | | | | | 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.
* Add copyright header to config/djgpp/djcheck.sh.Joel Brobecker2012-06-052-0/+19

* stubs/ia64vms-stub.c: Fix copyright header.Joel Brobecker2012-06-052-1/+6
| | | | | | | | | | 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.
* copyright.py: Update path to gnulib import.Joel Brobecker2012-06-052-2/+9
| | | | | | | | | | | 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.
