/* This file specifies a list of internal "functions".  These functions
   differ from built-in functions in that they have no linkage and cannot
   be called directly by the user.  They represent operations that are only
   synthesised by GCC itself.

   Internal functions are used instead of tree codes if the operation
   and its operands are more naturally represented as a GIMPLE_CALL
   than a GIMPLE_ASSIGN.

   Each entry in this file has the form:

     DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC)

   where NAME is the name of the function, FLAGS is a set of
   ECF_* flags and FNSPEC is a string describing functions fnspec.
   
   Each entry must have a corresponding expander of the form:

     void expand_NAME (gimple_call stmt)

   where STMT is the statement that performs the call.  */
