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 the form: 30 31 DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC) 32 33 where NAME is the name of the function, FLAGS is a set of 34 ECF_* flags and FNSPEC is a string describing functions fnspec. 35 36 Each entry must have a corresponding expander of the form: 37 38 void expand_NAME (gimple_call stmt) 39 40 where STMT is the statement that performs the call. */ 41 42DEF_INTERNAL_FN (LOAD_LANES, ECF_CONST | ECF_LEAF, NULL) 43DEF_INTERNAL_FN (STORE_LANES, ECF_CONST | ECF_LEAF, NULL) 44DEF_INTERNAL_FN (GOMP_SIMD_LANE, ECF_NOVOPS | ECF_LEAF | ECF_NOTHROW, NULL) 45DEF_INTERNAL_FN (GOMP_SIMD_VF, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 46DEF_INTERNAL_FN (GOMP_SIMD_LAST_LANE, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 47DEF_INTERNAL_FN (LOOP_VECTORIZED, ECF_NOVOPS | ECF_LEAF | ECF_NOTHROW, NULL) 48DEF_INTERNAL_FN (MASK_LOAD, ECF_PURE | ECF_LEAF, NULL) 49DEF_INTERNAL_FN (MASK_STORE, ECF_LEAF, NULL) 50DEF_INTERNAL_FN (ANNOTATE, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 51DEF_INTERNAL_FN (UBSAN_NULL, ECF_LEAF | ECF_NOTHROW, ".R.") 52DEF_INTERNAL_FN (UBSAN_BOUNDS, ECF_LEAF | ECF_NOTHROW, NULL) 53DEF_INTERNAL_FN (UBSAN_VPTR, ECF_LEAF | ECF_NOTHROW, ".RR..") 54DEF_INTERNAL_FN (UBSAN_CHECK_ADD, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 55DEF_INTERNAL_FN (UBSAN_CHECK_SUB, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 56DEF_INTERNAL_FN (UBSAN_CHECK_MUL, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 57DEF_INTERNAL_FN (UBSAN_OBJECT_SIZE, ECF_LEAF | ECF_NOTHROW, NULL) 58DEF_INTERNAL_FN (ABNORMAL_DISPATCHER, ECF_NORETURN, NULL) 59DEF_INTERNAL_FN (BUILTIN_EXPECT, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 60DEF_INTERNAL_FN (ASAN_CHECK, ECF_TM_PURE | ECF_LEAF | ECF_NOTHROW, ".R...") 61DEF_INTERNAL_FN (ADD_OVERFLOW, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 62DEF_INTERNAL_FN (SUB_OVERFLOW, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 63DEF_INTERNAL_FN (MUL_OVERFLOW, ECF_CONST | ECF_LEAF | ECF_NOTHROW, NULL) 64DEF_INTERNAL_FN (TSAN_FUNC_EXIT, ECF_NOVOPS | ECF_LEAF | ECF_NOTHROW, NULL) 65
