================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUAnnotateUniformValues.cpp:115
+ // Store defines the load and thus clobbers it.
+ (Q.isDef() && isa<StoreInst>(Q.getInst())))
return true;
----------------
Specifically checking for store instructions is going to be wrong since many other instruction types can also write to memory
