From cd76b525eda02c30c4412698a2ff309b975d417a Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Tue, 22 Nov 2016 14:05:05 +0000 Subject: [PATCH] gdbarch software_single_step frame_info to regcache: sparc gdb: 2016-11-22 Yao Qi * sparc-tdep.c (sparc_analyze_control_transfer): Replace parameter frame with regcache.
