--- Comment #4 from William J. Schmidt <wschmidt at gcc dot gnu.org> 2012-06-12 19:05:55 UTC ---
So, appears to be a target issue.  The only other use of L1_CACHE_SIZE in the
top-level gcc directory is in tree-ssa-loop-prefetch.c, where 0 is apparently
undetected but causes prefetching to be quietly disabled.  Specifying 0 doesn't
appear to be intentionally valid.
