Description Andy Hutchinson 2008-07-23 00:19:23 UTC 
For AVR the following test fail. Probably since the day they were created.

For AVR there are no "vectypes"  so they all fail  message test

I don't know if these should be skipped as invalid or there is some significant issue that warrant XFAIL.

	PR testsuite/36903
	* gcc.dg/tree-ssa/gen-vect-11.c : Disable for avr target. It will not vectorize.
	* gcc.dg/tree-ssa/gen-vect-11a.c: Ditto.
	* gcc.dg/tree-ssa/gen-vect-2.c: Ditto.
	* gcc.dg/tree-ssa/gen-vect-25.c: Ditto.
	* gcc.dg/tree-ssa/gen-vect-26.c: Ditto.
	* gcc.dg/tree-ssa/gen-vect-28.c: Ditto.
	* gcc.dg/tree-ssa/gen-vect-32.c: Ditto.
	* gcc.dg/tree-ssa/pr23455.c: Test for 4 eliminations on avr target.
	* gcc.dg/tree-ssa/ssa-fre-26.c: XFAIL test for avr.
	* gcc.dg/tree-ssa/vrp47.c: Skip test for avr target due to low branch cost.

Fixed 4.5. AVR wont vectorize with word size of 1 byte!
