Subject: Assume FreeBSD hosts include support for fetching signal information.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1f17d372496e18f93cad8ccec15d83530e41206f;p=binutils-gdb.git

Assume FreeBSD hosts include support for fetching signal information.

The current layout of siginfo_t and support for fetching it has been
included in FreeBSD kernels since 7.0 release.  The most recent
release without support is 6.4 released in November of 2008.

gdb/ChangeLog:

	* fbsd-nat.c: Always include support for
	TARGET_OBJECT_SIGNAL_INFO.
