; support.  When the Altivec limitation diagnostic is removed, this test
; should compile clean and fail in order to alert the author to validate the
; instructions emitted to initialize the GPR for the double vararg.
; The mfvsrwz and mfvsrd instructions should be used to initialize the GPR for
; the double vararg without going through memory.
