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.

RS		 41 DEF_INTERNAL_OPTAB_FN defines an internal function that maps to a
42 direct optab. The function should only be called with a given
43 set of types if the associated optab is available for the modes
44 of those types. OPTAB says what optab to use (without the trailing
45 "_optab") and TYPE categorizes the optab based on its inputs and
46 outputs. The possible types of optab are:
47
48 - mask_load: currently just maskload
49 - load_lanes: currently just vec_load_lanes
7e11fc7f 50 - mask_load_lanes: currently just vec_mask_load_lanes
db3efdaf 51 - gather_load: used for {mask_,len_mask,}gather_load
d496134a 52 - len_load: currently just len_load

0972596e 65
00eab0c6
RS		 66 - unary_convert: a single-input conversion optab, such as
67 lround<srcmode><dstmode>2.

16d24520
RS		 79 DEF_INTERNAL_SIGNED_OPTAB_FN defines an internal function that
80 maps to one of two optabs, depending on the signedness of an input.
81 SIGNED_OPTAB and UNSIGNED_OPTAB are the optabs for signed and
82 unsigned inputs respectively, both without the trailing "_optab".
83 SELECTOR says which type in the tree_pair determines the signedness.
84
686ee971
RS		 85 DEF_INTERNAL_FLT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition,
86 the function implements the computational part of a built-in math
87 function BUILT_IN_<NAME>{F,,L}. Unlike some built-in functions,
88 these internal functions never set errno.
89
4959a752
RS		 90 DEF_INTERNAL_INT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition
91 says that the function extends the C-level BUILT_IN_<NAME>{,L,LL,IMAX}
92 group of functions to any integral mode (including vector modes).
93
2f482a07
AV		 94 DEF_INTERNAL_WIDENING_OPTAB_FN is a wrapper that defines five internal
95 functions with DEF_INTERNAL_SIGNED_OPTAB_FN:
96 - one that describes a widening operation with the same number of elements
97 in the output and input vectors,
98 - two that describe a pair of high-low widening operations where the output
99 vectors each have half the number of elements of the input vectors,
100 corresponding to the result of the widening operation on the top half and
101 bottom half, these have the suffixes _HI and _LO,
102 - and two that describe a pair of even-odd widening operations where the
103 output vectors each have half the number of elements of the input vectors,
104 corresponding to the result of the widening operation on the even and odd
105 elements, these have the suffixes _EVEN and _ODD.
106 These five internal functions will require two optabs each, a SIGNED_OPTAB
107 and an UNSIGNED_OTPAB.
108
b78475cf 109 Each entry must have a corresponding expander of the form:
25583c4f 110
538dd0b7 111 void expand_NAME (gimple_call stmt)
25583c4f 112
ab23f5d9
RS		 113 where STMT is the statement that performs the call. These are generated
114 automatically for optab functions and call out to a function or macro
115 called expand_<TYPE>_optab_fn. */
