Subject: [2nd RFA] Make core dumps work on Irix
Date: Tue, 13 Feb 2001 15:07:00 -0000
Message-id: <200102132307.SAA18519@panix2.panix.com>
X-SW-Source: 2001-02/msg00191.html

The enclosed patch makes GDB able to again read core dumps on Irix.
It broke some time after GDB 4.18 (which works).

Andrew Cagney is listed as the MIPS maintainer.

It was previously submitted as
http://sources.redhat.com/ml/gdb-patches/2001-02/msg00161.html and its
companion patch is
