[PATCH v14 0/5] remove-symbol-file & add-symbol-file

[Nicolas Blanc <nicolas.blanc@intel.com>]

Adjust Patch 3/5 to reflect modification of struct target_section
from upstream. Thanks Luis for pointing this out.

The patch set was tested on x86_64 (Fedora 15) and x86 (Ubuntu 12.04).
No regression was detected.

Regards,

Nicolas

Changes between v13 and v3

* symfile.c (add_target_sections_of_objfile): Reflect modification
  of struct target_section from upstream.
  (symfile_free_objfile): Reflect modification of struct target_section
  from upstream.

Changes between v12 and v13

* Changed "is_elf_target" to "is_known_elf_target" (Patch 4/5)
  according to Doug's proposal
  (http://sourceware.org/ml/gdb-patches/2013-07/msg00426.html).

* Removed dependency to <elf.h> according to Mark's suggestion
  (http://sourceware.org/ml/gdb-patches/2013-07/msg00415.html).

Changes between v11 and v12

* symfile.c (add_target_sections_of_objfile): Reflect modification
  of struct target_section from upstream.

* gdb.base/sym-file-main.c: Move loader into a separate file as suggested
  and implemented the other recommendations from Doug.

* gdb.base/sym-file-loader.c: New file.

* gdb.base/sym-file-loader.h: New file.

* lib/gdb.exp (is_elf_target): New function.

Changes between v10 and v11:

* Changed documentation for add-symbol-file according to feedback (Patch 3):
  "keeps adding to" -> "is kept in addition to".

* Fixed indentation issues in test (sym-file-main.c from Patch 2).

Changes between v9 and v10:

* Dropped "USAGE" in "USAGE: remove-symbol-file FILENAME" according to suggestion.

* Fixed comment according to suggestion:
  "any reference to any objfile" -> "all references to any objfile"

* Added argument names to the prototype of is_addr_in_objfile according to suggestion.

* Fixed indentation of "macro" loops according to feedback.

* Fixed indentation issues.

Changes between v8 and v9:

* Patch 4: New patch (fix  add-symbol-file for 'info files').
* Patch 5: New patch (test add-symbol-file and 'info files');

* sym-file.exp: Fixed test name string.

Changes between v7 and v8:

* sym-file.exp: Call gdb_get_line_number with ${libfile}.c intead of $libsrc.

* Fixed typo in commit message for Patch 2/3.

Changes between v6 and v7:

* Changed disable_breakpoints_in_freed_objfile () from feedback:
  Use is_breakpoint () and is_tracepoint ().
  Add call to mark_breakpoint_location_modified ().

* Changed command description according to suggestion.

* Changed commit log message for new functions according to feedback.

* Fixed nits in gdb/solib.c and testsuite/gdb.base/sym-file.exp.

Changes between v5 and v6:

* Changed syntax of the command according to feedback:
    remove-symbol-file FILENAME
    remove-symbol-file -a ADDRESS

* Updated the documentation for the new syntax.

* Updated the test for the new syntax.

* Added check to only remove objfiles from the current program space.

Changes between v4 and v5:

* The address parameter can now be any address mapping into one of the sections
  of the file to remove. This is more flexible and more judicious because the symbol
  file may have no text section, as pointed out in some reviews.

* Move is_addr_in_objfile from breakpoint.c to objfiles.c. This new function
  is now used in both symfile.c and breakpoint.c.

* is_addr_in_objfile returns now 0 if OBJFILE is NULL.

* Updated the documentation to reflect the command change.

* Removed double blank lines.

* Reworded the log entries in the commit messages, as suggested.

* The test was simplified using prepare_for_testing, as suggested.

Changes between v3 and v4:

* gdb/symfile.c: add missing space character in output string.

* gdb/doc/gdb.texinfo: add usage example.

Changes between v2 and v3:

* gdb/breakpoints.c (disable_breakpoints_in_freed_objfile):
  Changed name of disable_breakpoints_in_free_objfile to disable_breakpoints_in_freed_objfile.
  Call observer_breakpoint_modified at most one time per breakpoint.

* gdb/objfiles.h (struct objfile): Add comment for low_addr.

* gdb/solib.c (remove_user_added_objfile): Don't check OBJF_SHARED anymore to avoid leaving dangling pointers.

* gdb/symfile.c (add_symbol_file_command): Parse and evaluate the address parameter only once.

* gdb/symfile.c (remove_symbol_file_command): Don't use gdb_buildargv anymore. Ask the user for confirmation before removing a file.

* gdb/doc/gdb.texinfo: The parameter of the command is now referred to as "the address of the text section".

* gdb/NEWS: Move the entry for remove-symbol-file to "Changes since GDB 7.6". The address parameter is now referred to as "the beginning of the text section".

* Fixed letter case of variables in comments.

* Fixed indentation typos.
