[LLVMdev] getelementptr with dynamic index

[Carl-Philip Hänsch]

Hi,

the following llvm-ir is manipulated by the optimizers:
%target2 = getelementptr %.string %result, i32 0, i32 3, i32 %len1
(%_.string = type {i32, i32, i32, [0 x i8]})

the last parameter i32 %len1 is replaced by i32 0 by the optimizers. (both,
2.9 and 2.8). When i turn optmization off, it works correctly.
How can i use an optimizer-safe dynamic indexing of arrays?
