[LLVMdev] code generation removes duplicated instructions
Hello,
I am duplicating few instructions in a basic block and splitting it. The
following is an example.
bb: ; preds = %bb1
%0 = load i32* %i, align 4
%1 = getelementptr inbounds [100 x i32]* %a, i32 0, i32 %0
store i32 0, i32* %1, align 4
%2 = load i32* %i, align 4
%3 = getelementptr inbounds [100 x i32]* %last_added, i32 0, i32 %2
store

and inserting comparison to catch transient errors.
IR BB:
bb: ; preds = %bb1.split
%0 = load i32* %i, align 4
%HV10_ = getelementptr inbounds [100 x i32]* %a, i32 0, i32 %0
%1 = getelementptr inbounds [100 x i32]* %a, i32 0, i32 %0
%HVCmp15 = icmp ne i32* %1, %HV10_
br i1 %HVCmp15, label %relExit, label %bb.split
