Description:   Last confirmed: Opened: 2008-06-18 22:53 
Test testsuite/gcc.dg/builtin-return-1.c will fail for avr target.

Default implementation of builtin-return-1 is untyped return of a single
register.
Which is R25 and only 1 byte. This is not int as test expects.
So high byte may and does get overwritten before outer return.

The test may be invalid, but this is also reminder that AVR target does not
have a complete definition for untyped return. The default is pretty useless.

Test with be marked XFAIL.
