[LLVMdev] compare two GEP instructions operand by operand

[Jimborean Alexandra]

Hi,

I have a question regarding the GEP instruction. Is 
it correct to consider that two GEP instructions compute the same memory address if and only if all their corresponding fields are equal? 


For instance, for a two-dimensional array of integers, can we have two GEP instructions that are equal? 


  %arrayidx = getelementptr [10 x [30 x i32]]* @main.B, i64 0, i64 0, i64 %tmp157

  %tmp = load i32* getelementptr inbounds ([10 x [30 x i32]]* @main.B, i64 0, i64 3, i64 10), align 8

although their corresponding indices are different? For instance if %tmp157 goes out of the bounds of the line 0 and computes the address of the 10th 
element in line 3.


Thank you,Alexandra
