[PATCH] D40113: AMDGPU: Fix crash when scheduling DBG_VALUE

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added inline comments.


================
Comment at: lib/Target/AMDGPU/GCNSchedStrategy.cpp:333
   Unsched.reserve(NumRegionInstrs);
-  for (auto &I : *this)
-    Unsched.push_back(&I);
+  for (auto &I : *this) {
+    if (!I.isDebugValue())
----------------
I am afraid this will push RegionBegin iterator. Maybe you need to skip a debug value in the loop at line 389 instead.
