Here is an updated version of this patch.
Tulio noted that glibc's strncmp test was failing. This turned out to
be the use of signed HOST_WIDE_INT for handling strncmp length. The
glibc test calls strncmp with length 2^64-1, presumably to provoke
exactly this type of bug. Fixing the issue required changing
select_block_compare_mode() and expand_block_compare() as well.
The other change is if we must emit a runtime check for the 4k
crossing, then we might as well set base_align to 8 and emit the best
possible code.
OK for trunk if bootstrap/regtest passes on ppc64/ppc64le?
Thanks,
Aaron
