...uction. I have taken the code from line 632 and line 757 of safecode/lib/ArrayBoundsChecks/ArrayBoundCheck.cpp I must be doing something wrong, what is it?

[LLVMdev] Pointers in Load and Store
When I compile C programs into llvm, it produces load instructions in two different flavours. (1) %8 = load i8** %bp, align 8 (2) %1 = load i8* getelementptr inbounds ([4 x i8]* @.str, i64 0, i64 0), align 1 I know that %bp in first case and the entire "getelementptr inbounds ([4 x i8]* @.str, i64 0, i64 0)" in second case can be obtained by dump'ing I.getOperand(0)
