+ * breakpoint.h (enum bptype): New type bp_through_sigtramp.
+ (bpstat_what_main_action): New code BPSTAT_WHAT_THROUGH_SIGTRAMP.
+ * breakpoint.c (bpstat_what): Return BPSTAT_WHAT_THROUGH_SIGTRAMP
+ if we hit a bp_through_sigtramp breakpoint. Remove kludge which
+ ignored bs->stop for a bp_step_resume breakpoint.
+ * infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
+ which performs one (the check_sigtramp2 one) of the functions
+ which had been handled by the step_resume_breakpoint. For each
+ use of the step_resume_breakpoint, make it still use the
+ step_resume_breakpoint, use the through_sigtramp_breakpoint, or
+ operate on both.
+ Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
+ When setting the frame address of the step resume breakpoint, set
+ it to the address for frame *before* the call instruction is
+ executed, not after.
