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.

ab23f5d9
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
bfaa08b7 51 - gather_load: used for {mask_,}gather_load
d496134a 52 - len_load: currently just len_load
ab23f5d9
RS		 53
54 - mask_store: currently just maskstore
55 - store_lanes: currently just vec_store_lanes
7e11fc7f 56 - mask_store_lanes: currently just vec_mask_store_lanes
f307441a 57 - scatter_store: used for {mask_,}scatter_store
d496134a 58 - len_store: currently just len_store
ab23f5d9 59
0972596e
RS		 60 - unary: a normal unary optab, such as vec_reverse_<mode>
61 - binary: a normal binary optab, such as vec_interleave_lo_<mode>
c566cc9f 62 - ternary: a normal ternary optab, such as fma<mode>4
0972596e 63
00eab0c6
RS		 64 - unary_convert: a single-input conversion optab, such as
65 lround<srcmode><dstmode>2.
66
b41d1f6e
RS		 67 - cond_binary: a conditional binary optab, such as cond_add<mode>
68 - cond_ternary: a conditional ternary optab, such as cond_fma_rev<mode>
0972596e 69
b781a135 70 - fold_left: for scalar = FN (scalar, vector), keyed off the vector mode
58c036c8 71 - check_ptrs: used for check_{raw,war}_ptrs
b781a135 72
16d24520
RS		 73 DEF_INTERNAL_SIGNED_OPTAB_FN defines an internal function that
74 maps to one of two optabs, depending on the signedness of an input.
75 SIGNED_OPTAB and UNSIGNED_OPTAB are the optabs for signed and
76 unsigned inputs respectively, both without the trailing "_optab".
77 SELECTOR says which type in the tree_pair determines the signedness.
78
686ee971
RS		 79 DEF_INTERNAL_FLT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition,
80 the function implements the computational part of a built-in math
81 function BUILT_IN_<NAME>{F,,L}. Unlike some built-in functions,
82 these internal functions never set errno.
83
4959a752
RS		 84 DEF_INTERNAL_INT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition
85 says that the function extends the C-level BUILT_IN_<NAME>{,L,LL,IMAX}
86 group of functions to any integral mode (including vector modes).
87
b78475cf 88 Each entry must have a corresponding expander of the form:
25583c4f 89
538dd0b7 90 void expand_NAME (gimple_call stmt)
25583c4f 91
ab23f5d9
RS		 92 where STMT is the statement that performs the call. These are generated
93 automatically for optab functions and call out to a function or macro
94 called expand_<TYPE>_optab_fn. */
