From 151c31785a61a25ca06d48691c0dfd5a487f8721 Mon Sep 17 00:00:00 2001 From: Paul Fertser Date: Sat, 12 Apr 2014 17:22:00 +0400 Subject: [PATCH] mips32, dsp563xx: fix segfault on Gdb attach Since c6216201b249e6a97fcc085e413e3d34e0de6fb7 gdb target description generation support is enabled by default and it counts on checking "feature" pointer in reg_list. Both mips32 and dsp563xx neither used calloc nor explicitly set feature (as it was a newly introduced struct field). This patch changes all targets to use calloc for consistency.
