Unfortunately, this test breaks spu-elf; a lot of tests now fail with:
loop-2f.c:(.text+0x100): undefined reference to `mmap'
The problem is that we *do* have sys/mman.h on SPU, it just does not
contain a mmap prototype (and there is no mmap routine). Instead,
sys/mman.h on SPU has prototypes and defines for "mmap_eaddr" and
the like, which allow SPU programs to manipulate PPU-side memory
mappings (to be accessed via DMA) ...
Can the test be extended to actually check for the mmap routine
itself?
Thanks,
Ulrich
