Subject: Make some bpstat functions use bool
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;ds=sidebyside;h=4c462cb0efb40a7a1e5297946bed59286dd0cf02;p=binutils-gdb.git

Make some bpstat functions use bool

Change return type to bool and adjust function comments.

gdb/ChangeLog:

	* breakpoint.h (bpstat_explains_signal, bpstat_causes_stop,
	bpstat_should_step): Return bool, adjust comments.
	* breakpoint.c (bpstat_explains_signal, bpstat_causes_stop,
	bpstat_should_step): Likewise.
