  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.
  24
  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.
  28
  29    Each entry in this file has the form:
  30
  31      DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC)
  32
  33    where NAME is the name of the function, FLAGS is a set of
  34    ECF_* flags and FNSPEC is a string describing functions fnspec.
  35
  36    Each entry must have a corresponding expander of the form:
  37
  38      void expand_NAME (gimple stmt)
  39
  40    where STMT is the statement that performs the call.  */
