The initialization of %a5. Anyway, it doesn't make mich sense to change 
this now and the main point is to avoid creation of a got entry for 
_GLOBAL_OFFSET_TABLE_@GOTPC, as it's already done.

Well, the point was that with -fPIC it shouldn't make a difference to use 
the pc as pic register (and even saves initialization), doesn't it?
With -fpic we might want to use an offset, so we can use the full 64K 
address range.
