[patch 2/2] Add hppa-linux target to gdb
- From: Randolph Chung <randolph at tausq dot org>
- To: gdb-patches at sources dot redhat dot com
- Date: Sun, 4 Apr 2004 10:45:32 -0700
- Subject: [patch 2/2] Add hppa-linux target to gdb
- Reply-to: Randolph Chung <randolph at tausq dot org>
Second of two patches incorporating comments from Eli and Dan. This
adds code to support hppa-linux as a target. Compared to the previous
version, tm-linux.h was removed in favor of the existing tm-hppa.h.
thanks
