This is expected behavior, you need to run loop rotate before licm to
get this. This is completely eliminate at -O3.

[LLVMdev] LICM
Hi all,
I just noticed that LICM does not hoist/sink the following store out of
the loop:
int array[20];
int i;
for (i = 0; i<100; i++) {
array [0] = 0;
}
The getElementPtr instruction is hoisted out of the loop; the store is
not. Did I miss something obvious? Bitcode file attached.

Thanks for the report. Since this still happens with LLVM at the top of SVN,
I filed it as http://llvm.org/PR5319 . Please add yourself to the cc list
there.
