Description
Feature or enhancement
(A clear and concise description of your proposal.)
memchr
is currently used if sizeof(STRINGLIB_CHAR) == sizeof(char)
because it faster
than the standard C loops alternatives.
wmemchr
has often roughly the same performance as memchr
and can be used
in the same way as memchr
to speedup some of the string functions STRINGLIB(find_char)
and STRINGLIB(replace_1char_inplace)
are the two easiest candidates.
Pitch
(Explain why this feature or enhancement should be implemented and how it would be used.
Add examples, if applicable.)
It would, in some instances, make wide_str.find(wide_str_of_len_one)
faster.
Previous discussion
The idea was discussed a bit in #69009 but wasn't the main topic of the issue
or put into any patches.
