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 one of the forms: 30 31 DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC) 32 DEF_INTERNAL_OPTAB_FN (NAME, FLAGS, OPTAB, TYPE) 33 DEF_INTERNAL_SIGNED_OPTAB_FN (NAME, FLAGS, SELECTOR, SIGNED_OPTAB, 34 UNSIGNED_OPTAB, TYPE) 35 DEF_INTERNAL_FLT_FN (NAME, FLAGS, OPTAB, TYPE) 36 DEF_INTERNAL_INT_FN (NAME, FLAGS, OPTAB, TYPE) 37 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 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 50 - mask_load_lanes: currently just vec_mask_load_lanes 51 - gather_load: used for {mask_,}gather_load 52 53 - mask_store: currently just maskstore 54 - store_lanes: currently just vec_store_lanes 55 - mask_store_lanes: currently just vec_mask_store_lanes 56 - scatter_store: used for {mask_,}scatter_store 57 58 - unary: a normal unary optab, such as vec_reverse_<mode> 59 - binary: a normal binary optab, such as vec_interleave_lo_<mode> 60 - ternary: a normal ternary optab, such as fma<mode>4 61 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> 64 65 - fold_left: for scalar = FN (scalar, vector), keyed off the vector mode 66 - check_ptrs: used for check_{raw,war}_ptrs 67 68 DEF_INTERNAL_SIGNED_OPTAB_FN defines an internal function that 69 maps to one of two optabs, depending on the signedness of an input. 70 SIGNED_OPTAB and UNSIGNED_OPTAB are the optabs for signed and 71 unsigned inputs respectively, both without the trailing "_optab". 72 SELECTOR says which type in the tree_pair determines the signedness. 73 74 DEF_INTERNAL_FLT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition, 75 the function implements the computational part of a built-in math 76 function BUILT_IN_<NAME>{F,,L}. Unlike some built-in functions, 77 these internal functions never set errno. 78 79 DEF_INTERNAL_INT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition 80 says that the function extends the C-level BUILT_IN_<NAME>{,L,LL,IMAX} 81 group of functions to any integral mode (including vector modes). 82 83 Each entry must have a corresponding expander of the form: 84 85 void expand_NAME (gimple_call stmt) 86 87 where STMT is the statement that performs the call. These are generated 88 automatically for optab functions and call out to a function or macro 89 called expand_<TYPE>_optab_fn. */ 90 91#ifndef DEF_INTERNAL_FN 92#define DEF_INTERNAL_FN(CODE, FLAGS,
