/* Test failed on an architecture that:

   - had 16-bit registers,

   - passed 64-bit structures in registers,

   - only allowed SImode values in even numbered registers.

   Before reload, s.i2 in foo() was represented as:

        (subreg:SI (reg:DI 0) 2)

   find_dummy_reload would return (reg:SI 1) for the subreg reload,
