exec_close uses the current program space, so it seemed cleaner to
change it to be a method on program_space. This patch makes this
change.
gdb/ChangeLog
2020-10-19 Tom Tromey <tom@tromey.com>
* progspace.c (program_space::exec_close): New method, from
exec_close in exec.c.
* exec.c (exec_close): Move to progspace.c.
(exec_target::close, exec_file_attach): Update.
* progspace.h (struct program_space) <exec_close>: Declare
method.
