[PATCH 2/3] gdbserver: introduce threads_debug_printf, THREADS_SCOPED_DEBUG_ENTER_EXIT
Simon Marchi
simon.marchi@polymtl.ca
Mon Jan 17 21:27:51 GMT 2022
Add the threads_debug_printf and THREADS_SCOPED_DEBUG_ENTER_EXIT, which
use the logging infrastructure from gdbsupport/common-debug.h. Replace
all debug_print uses that are predicated by debug_threads with
threads_dethreads_debug_printf. Replace uses of the debug_enter and
debug_exit macros with THREADS_SCOPED_DEBUG_ENTER_EXIT, which serves
essentially the same purpose, but allows showing what comes between the
enter and the exit in an indented form.
Note that "threads" debug is currently used for a bit of everything in
GDBserver, not only threads related stuff. It should ideally be cleaned
up and separated logically as is done in GDB, but that's out of the
scope of this patch.
