20 /* This file specifies a list of internal "functions". These functions
21 differ from built-in functions in that they have no linkage and cannot
22 be called directly by the user. They represent operations that are only
23 synthesised by GCC itself.
25 Internal functions are used instead of tree codes if the operation
26 and its operands are more naturally represented as a GIMPLE_CALL
27 than a GIMPLE_ASSIGN.
29 Each entry in this file has the form:
31 DEF_INTERNAL_FN (NAME, FLAGS)
33 where NAME is the name of the function and FLAGS is a set of
34 ECF_* flags. Each entry must have a corresponding expander
35 of the form:
37 void expand_NAME (gimple stmt)
39 where STMT is the statement that performs the call. */
41 DEF_INTERNAL_FN (LOAD_LANES, ECF_CONST | ECF_LEAF)
42 DEF_INTERNAL_FN (STORE_LANES, ECF_CONST | ECF_LEAF)
