Hello!

Add --param min-insn-to-prefetch-ratio=0 to avoid "Not prefetching --
instruction to prefetch ratio (6) too small" aprefetch pass rejection.

2011-05-05  Uros Bizjak  <ubizjak@gmail.com>

	* gcc.target/i386/opt-1.c: Add --param min-insn-to-prefetch -ratio=0
	to dg-options.
	* gcc.target/i386/opt-1.c: Ditto.

Tested on x86_64-pc-linux-gnu {,-m32} AVX target, committed to mainline SVN.

Uros.
