Ok, here is an updated patch. Added _Bool support for arg2 (and testcase coverage for that in the first testcase and removed from second), if arg2 is unsigned or when sanitizing shifts it uses arg2 % prec and if not sanitizing shifts and arg2 is signed, it just uses (utype2) arg2 % prec because that will IMHO result in better code generation (e.g. for power of 2 precisions bitwise AND and on some arches even no bitwise AND, just get it for free). The only changed parts are extend.texi, c-parser.cc and the 2 testcases. 2024-10-24 Jakub Jelinek PR c/117030 gcc/ * doc/extend.texi (__builtin_stdc_rotate_left, __builtin_stdc_rotate_right): Document. gcc/c-family/ * c-common.cc (c_common_reswords): Add __builtin_stdc_rotate_left and __builtin_stdc_rotate_right. gcc/c/ * c-parser.cc: Include asan.h and c-family/c-ubsan.h.
