INTEGER, LOGICAL and REAL*4 are returned in D0.  REAL*8 results are returned
in D0 and D1.  All COMPLEX, CHARACTER and RECORD/STRUCTURE results are
returned on the stack.

So, yes, it is the same as C's convention.

The manual "HP-UX Assembler Reference and Supporting Documents" (part number
98597-90020) has all the details.
