/* 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 one of the forms:
DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC)
DEF_INTERNAL_OPTAB_FN (NAME, FLAGS, OPTAB, TYPE)
DEF_INTERNAL_FLT_FN (NAME, FLAGS, OPTAB, TYPE)
DEF_INTERNAL_INT_FN (NAME, FLAGS, OPTAB, TYPE)
where NAME is the name of the function, FLAGS is a set of
ECF_* flags and FNSPEC is a string describing functions fnspec.
DEF_INTERNAL_OPTAB_FN defines an internal function that maps to a
direct optab. The function should only be called with a given
set of types if the associated optab is available for the modes
of those types. OPTAB says what optab to use (without the trailing
"_optab") and TYPE categorizes the optab based on its inputs and
outputs. The possible types of optab are:
- mask_load: currently just maskload
- load_lanes: currently just vec_load_lanes
- mask_store: currently just maskstore
- store_lanes: currently just vec_store_lanes
DEF_INTERNAL_FLT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition,
the function implements the computational part of a built-in math
function BUILT_IN_<NAME>{F,,L}. Unlike some built-in functions,
these internal functions never set errno.
DEF_INTERNAL_INT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition
says that the function extends the C-level BUILT_IN_<NAME>{,L,LL,IMAX}
group of functions to any integral mode (including vector modes).
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. These are generated
automatically for optab functions and call out to a function or macro
called expand_<TYPE>_optab_fn. */
