- instruction does not automatically preserves them. If the
- transaction body is fully contained in a function the backend tries
- after reload to get rid of the FPR save/restore operations
- triggered by the clobbers. This testcase failed since the backend
- was able to get rid of all FPR saves/restores and since these were
- the only stack operations also of the entire stack space. So even
- the save/restore of the stack pointer was omitted in the end.
- However, since the frame layout has been fixed before, the prologue
- still generated the stack pointer decrement making foo return with
- a modified stack pointer. */
