From b933066ae03d924a92b2616b4a24e7d91cd5b841 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Thu, 17 Sep 2015 15:58:10 -0700 Subject: target-*: Introduce and use cpu_breakpoint_test Reduce the boilerplate required for each target. At the same time, move the test for breakpoint after calling tcg_gen_insn_start. Note that arm and aarch64 do not use cpu_breakpoint_test, but still move the inline test down after tcg_gen_insn_start.
