From 598cc9dc84aeaa66e4a77efa9dc8ff03d5532620 Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Thu, 3 Nov 2016 14:35:13 +0000 Subject: GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION Many archs have only one kind of breakpoint, so their breakpoint_from_pc implementations are quite similar. This patch uses macro GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION for breakpoint_from_pc, so that we can easily switch from breakpoint_from_pc to breakpoint_kind_from_pc and sw_breakpoint_from_kind later. gdb: 2016-11-03 Yao Qi * arch-utils.h (GDBARCH_BREAKPOINT_MANIPULATION): New macro. (SET_GDBARCH_BREAKPOINT_MANIPULATION): New macro. aarch64-tdep.c (aarch64_breakpoint_from_pc): Remove. Use GDBARCH_BREAKPOINT_MANIPULATION.
