/* A C expression which can inhibit the returning of certain function
values in registers, based on the type of value. A nonzero value
says to return the function value in memory, just as large
structures are always returned. Here TYPE will be a C expression
of type `tree', representing the data type of the value.
Note that values of mode `BLKmode' must be explicitly handled by
this macro. Also, the option `-fpcc-struct-return' takes effect
regardless of this macro. On most systems, it is possible to
leave the macro undefined; this causes a default definition to be
used, whose value is the constant 1 for `BLKmode' values, and 0
otherwise.
Do not use this macro to indicate that structures and unions
should always be returned in memory. You should instead use
`DEFAULT_PCC_STRUCT_RETURN' to indicate this. */
