/* This header provides a declaritive way of describing the types that
|
||
|
|
are used when declaring builtin functions.
|
||
|
|
|
||
|
|
Before including this header, you must define the following macros:
|
||
|
|
|
||
|
|
DEF_PRIMITIVE_TYPE (ENUM, TYPE)
|
||
|
|
|
||
|
|
The ENUM is an identifier indicating which type is being defined.
|
||
|
|
TYPE is an expression for a `tree' that represents the type.
|
||
|
|
|
||
|
|
DEF_FUNCTION_TYPE_0 (ENUM, RETURN)
|
||
|
|
DEF_FUNCTION_TYPE_1 (ENUM, RETURN, ARG1)
|
||
|
|
DEF_FUNCTION_TYPE_2 (ENUM, RETURN, ARG1, ARG2)
|
||
|
|
DEF_FUNCTION_TYPE_3 (ENUM, RETURN, ARG1, ARG2, ARG3)
|
||
|
|
DEF_FUNCTION_TYPE_4 (ENUM, RETURN, ARG1, ARG2, ARG3, ARG4)
|
||
|
|
|
||
|
|
These macros describe function types. ENUM is as above. The
|
||
|
|
RETURN type is one of the enumerals already defined. ARG1, ARG2,
|
||
|
|
and ARG3 give the types of the arguments, similarly.
|
||
|
|
|
||
|
|
DEF_FUNCTION_TYPE_VAR_0 (ENUM, RETURN)
|
||
|
|
DEF_FUNCTION_TYPE_VAR_1 (ENUM, RETURN, ARG1)
|
||
|
|
DEF_FUNCTION_TYPE_VAR_2 (ENUM, RETURN, ARG1, ARG2)
|
||
|
|
|
||
|
|
Similar, but for function types that take variable arguments.
|
||
|
|
For example:
|
||
|
|
|
||
|
|
DEF_FUNCTION_TYPE_1 (BT_INT_DOUBLE, BT_INT, BT_DOUBLE)
|
||
|
|
|
||
|
|
describes the type `int ()(double)', using the enumeral
|
||
|
|
BT_INT_DOUBLE, whereas:
|
||
|
|
|
||
|
|
DEF_FUNCTION_TYPE_VAR_1 (BT_INT_DOUBLE_VAR, BT_INT, BT_DOUBLE)
|
||
|
|
|
||
|
|
describes the type `int ()(double, ...)'.
|
||
|
|
|
||
|
|
DEF_POINTER_TYPE (ENUM, TYPE)
|
||
|
|
|
||
|
|
This macro describes a pointer type. ENUM is as above; TYPE is
|
||
|
|
the type pointed to. */
