From 801bf7ebbed34577e730a53d6575035c26e39ac1 Mon Sep 17 00:00:00 2001 From: Shiva Chen Date: Wed, 9 May 2018 02:42:00 +0000 Subject: [DebugInfo] Examine all uses of isDebugValue() for debug instructions. Because we create a new kind of debug instruction, DBG_LABEL, we need to check all passes which use isDebugValue() to check MachineInstr is debug instruction or not. When expelling debug instructions, we should expel both DBG_VALUE and DBG_LABEL. So, I create a new function, isDebugInstr(), in MachineInstr to check whether the MachineInstr is debug instruction or not. This patch has no new test case. I have run regression test and there is no difference in regression test.
