Oh I thought that it is only for x86...
The problem is that the option -msse2 is somehow used to compile this
and therfore the following statement is generated.
movapd .LC4, %xmm0
I do not see how this test case can test anything unless it scans
the assembler output for this instruction. Maybe there is something
special in the -fdump-tree-xxx that should be looked for?
