- References: <20150326205727 dot 28223 dot 54648 dot stgit at host1 dot jankratochvil dot net>
Provide a way to associate more data with enum compile_i_scope_types up to the
struct do_module_cleanup stage.
It should be all sub-classed but AFAIK GDB does not require C++ compiler yet.
gdb/ChangeLog
2015-03-26 Jan Kratochvil <jan.kratochvil@redhat.com>
* cli/cli-script.c (execute_control_command): Update
eval_compile_command caller.
* compile/compile-object-load.h (struct compile_module): Add field
scope_data.
* compile/compile-object-run.c (struct do_module_cleanup): Add field
scope_data.
(compile_object_run): Propage the field scope_data.
* compile/compile.c (compile_file_command, compile_code_command):
Update eval_compile_command callers.
(eval_compile_command): Add parameter scope_data. Set it.
* compile/compile.h (eval_compile_command): Add parameter scope_data.
* defs.h (struct command_line): Add field scope_data.
