Subject: * i386nbsd-tdep.c (i386nbsd_sigtramp_offset): Change argument from
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=24f9f5e3538cb7eed26f8951315ee73aca8885d6;p=binutils-gdb.git

* i386nbsd-tdep.c (i386nbsd_sigtramp_offset): Change argument from
CORE_ADDR to struct frame_info *.  Use safe_frame_unwind_memory
instead of deprecated_read_memory_nobpt.
(i386nbsd_sigtramp_p): Adjust for changed signature of
i386nbsd_sigtramp_offset.
