From 93f9a11fbdb8f09428b17180d51a09a1bda39a52 Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Tue, 8 Nov 2016 14:28:32 +0000 Subject: gdbarch software_single_step returns VEC (CORE_ADDR) * This patch changes gdbarch method software_single_step to return a vector of addresses on which GDB should insert breakpoints, and don't insert breakpoints. Instead, the caller of gdbarch_software_single_step inserts breakpoints if the returned vector is not NULL. gdb: 2016-11-08 Yao Qi * aarch64-tdep.c (aarch64_software_single_step): Return VEC (CORE_ADDR) *.
