Subject: gdb: make watchpoint::val_valid a bool
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4c1d86d9a8f7ddfbf7ff095a88a59497c8f6ddc9;p=binutils-gdb.git

gdb: make watchpoint::val_valid a bool

gdb/ChangeLog:

	* breakpoint.h (struct watchpoint) <val_valid>: Change type to
	bool.
	* breakpoint.c (update_watchpoint): Assign false instead of 0,
	true instead of 1.
	(breakpoint_init_inferior): Likewise.
	(watchpoint_check): Likewise.
	(watch_command_1): Likewise.
	(invalidate_bp_value_on_memory_change): Likewise.
