+
+ Fix double parsing of filenames passed as command line arguments
+ to GDB (causes weird handling of escape characters).
+ Also, remove dependencies on the CLI from libgdb.
+ * call-cmds.h: Remove declaration of exec_file_command().
+ * gdbcore.h: Remove declaration of exec_file_command().
+ Add declarations for exec_open() and exec_file_clear().
+ * symfile.h: Add declarations for symbol_file_add_main() and
+ symbol_file_clear().
+ * exec.c (exec_open): New function. Implements to_open for exec
+ targets.
+ (exec_file_clear): New function. Makes GDB forget about a previously
+ specified executable file.
+ (exec_file_attach): Move parsing of arguments from here ...
+ (exec_file_command): ... to here.
+ (init_exec_ops): Use exec_open(), not exec_file_command() to
+ implement to_open for exec targets.
+ * symfile.c (symbol_file_add_main): New function. Call symbol_file_add()
+ with default values. Used when the file name has already been parsed.
+ (symbol_file_clear): New function. Makes GDB forget about previously
+ read symbols.
+ (symbol_file_command): Call the above function instead of inline code.
+ * main.c: Include "symfile.h" and "gdbcore.h" instead of the deprecated
+ "call-cmds.h".
+ (captured_main): Call exec_file_attach() and symbol_file_add_main()
+ instead of exec_file_command() and symbol_file_command().
+ (captured_main): Add comment.
+ * corefile.c: Include "symfile.h".
+ (core_file_command): Call symbol_file_add_main() instead of
+ symbol_file_command().
+ (reopen_exec_file): Call exec_open() instead of exec_file_command().
+ * infcmd.c: Include "symfile.h".
+ (attach_command): Call symbol_file_add_main() instead of
+ symbol_file_command().
+ * infrun.c: Remove comment about the inclusion of "symfile.h",
+ not any longer appropriate.
+ (follow_exec): Call symbol_file_add_main() instead of
+ symbol_file_command().
+ * remote-es.c: Include "symfile.h".
+ (es1800_load): Call symbol_file_add_main() instead of
+ symbol_file_command().
+ * remote-vx.c: Remove comment about the inclusion of "symfile.h",
+ not any longer appropriate.
+ (vx-wait): Call symbol_file_add_main() instead of
+ symbol_file_command().
+ * solib-svr4.c (open_symbol_file_object): Call symbol_file_add_main()
+ instead of symbol_file_command().
+ * v850ice.c (ice_file): Call exec_open(), exec_file_attach() and
+ symbol_file_add_main() instead of exec_file_command() and
+ symbol_file_command().
+ * Makefile.in: Update dependencies.
+

* remote-udi.c (udi_open): Change strdup to xstrdup.
