/* This header file defines a set of macros to be used in the construction
of parameter passing and/or va_arg code gen tests during the
pre-processing stage. It is included inside abitest.h.
The following macros are defined here:
LAST_ARG
ARG
DOTS
ANON
LAST_ANON
PTR
PTR_ANON
LAST_ANONPTR
These macros are given different definitions depending on which one of
the following macros is defined.
AARCH64_MACRO_DEF_CHECK_INCOMING_ARGS
AARCH64_MACRO_DEF_GEN_PARAM_TYPE_LIST
AARCH64_MACRO_DEF_GEN_ARGUMENT_LIST
AARCH64_VARIADIC_MACRO_DEF_GEN_PARAM_TYPE_LIST
AARCH64_VARIADIC_MACRO_DEF_GEN_PARAM_TYPE_LIST_WITH_IDENT
AARCH64_VARIADIC_MACRO_DEF_ASSIGN_LOCAL_VARS_WITH_ARGS
AARCH64_VARIADIC_MACRO_DEF_GEN_ARGUMENT_LIST
Do not define more than one of the above macros. */
