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
a2b6bdcd 29 Each entry in this file has one of the forms:
fb049fba 30
64d5d3e8 31 DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC)
a2b6bdcd 32 DEF_INTERNAL_OPTAB_FN (NAME, FLAGS, OPTAB, TYPE)
e53664fa 33 DEF_INTERNAL_SIGNED_OPTAB_FN (NAME, FLAGS, SELECTOR, SIGNED_OPTAB,
34 UNSIGNED_OPTAB, TYPE)
1f24b8e9 35 DEF_INTERNAL_FLT_FN (NAME, FLAGS, OPTAB, TYPE)
c9452b7c 36 DEF_INTERNAL_INT_FN (NAME, FLAGS, OPTAB, TYPE)
fb049fba 37
64d5d3e8 38 where NAME is the name of the function, FLAGS is a set of
39 ECF_* flags and FNSPEC is a string describing functions fnspec.
40
a2b6bdcd 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
2dd8e84c 50 - mask_load_lanes: currently just vec_mask_load_lanes
1619606c 51 - gather_load: used for {mask_,}gather_load
a2b6bdcd 52
53 - mask_store: currently just maskstore
54 - store_lanes: currently just vec_store_lanes
2dd8e84c 55 - mask_store_lanes: currently just vec_mask_store_lanes
0bf8b382 56 - scatter_store: used for {mask_,}scatter_store
a2b6bdcd 57
88fefa8f 58 - unary: a normal unary optab, such as vec_reverse_<mode>
59 - binary: a normal binary optab, such as vec_interleave_lo_<mode>
143c3c9a 60 - ternary: a normal ternary optab, such as fma<mode>4
88fefa8f 61
6682fc02 62 - cond_binary: a conditional binary optab, such as cond_add<mode>
63 - cond_ternary: a conditional ternary optab, such as cond_fma_rev<mode>
88fefa8f 64
d77809a4 65 - fold_left: for scalar = FN (scalar, vector), keyed off the vector mode
66
e53664fa 67 DEF_INTERNAL_SIGNED_OPTAB_FN defines an internal function that
68 maps to one of two optabs, depending on the signedness of an input.
69 SIGNED_OPTAB and UNSIGNED_OPTAB are the optabs for signed and
70 unsigned inputs respectively, both without the trailing "_optab".
71 SELECTOR says which type in the tree_pair determines the signedness.
72
1f24b8e9 73 DEF_INTERNAL_FLT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition,
74 the function implements the computational part of a built-in math
75 function BUILT_IN_<NAME>{F,,L}. Unlike some built-in functions,
76 these internal functions never set errno.
77
c9452b7c 78 DEF_INTERNAL_INT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition
79 says that the function extends the C-level BUILT_IN_<NAME>{,L,LL,IMAX}
80 group of functions to any integral mode (including vector modes).
81
64d5d3e8 82 Each entry must have a corresponding expander of the form:
fb049fba 83
1a91d914 84 void expand_NAME (gimple_call stmt)
fb049fba 85
a2b6bdcd 86 where STMT is the statement that performs the call. These are generated
87 automatically for optab functions and call out to a function or macro
88 called expand_<TYPE>_optab_fn. */
