In https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html#index-_005f_005fbuiltin_005fstdc_005fbit_005ffloor I've noticed that while e.g. __builtin_stdc_bit_floor builtin is properly rendered in bold and bigger size, for the __builtin_stdc_bit_width builtin it is not the builtin name which is marked like that, but the keyword int before it. Also, seems such builtins are missing from the index. I've read the texinfo docs and they seem to suggest in https://www.gnu.org/software/texinfo/manual/texinfo/html_node/Line-Macros.html that return types of functions with spaces in the return type should be wrapped with {}s and we already use that e.g. in @defbuiltin{{void *} __builtin_thread_pointer (void)} The following patch adjusts builtins I found which contained one or two spaces in the return type name (plus two spots which used 2 spaces after single keyword return type instead of 1 which triggered my search regex as well). Tested on x86_64-linux, ok for trunk? 2023-12-01 Jakub Jelinek * doc/extend.texi (__builtin_addc, __builtin_addcl, __builtin_addcll, __builtin_subc, __builtin_subcl, __builtin_subcll, __builtin_stdc_bit_width, __builtin_stdc_count_ones, __builtin_stdc_count_zeros, __builtin_stdc_first_leading_one, __builtin_stdc_first_leading_zero, __builtin_stdc_first_trailing_one, __builtin_stdc_first_trailing_zero, __builtin_stdc_has_single_bit, __builtin_stdc_leading_ones, __builtin_stdc_leading_zeros, __builtin_stdc_trailing_ones, __builtin_stdc_trailing_zeros, __builtin_nvptx_brev, __builtin_nvptx_brevll, __builtin_darn, __builtin_darn_raw, __builtin_ia32_vec_ext_v2di, __builtin_ia32_crc32qi, __builtin_ia32_crc32hi, __builtin_ia32_crc32si, __builtin_ia32_crc32di): Put {}s around return type with spaces in it.
