Tests failing on ARM64: getopt and (un)signed char about swift HOT 5 CLOSED

Thanks.

Ah the good memories of the char convention on ARM...

A short-term solution is to allow warnings by configuring SWIFT with --enable-compiler-warnings. It does not solve the actual problem but will let the code compile.

getopt() should return an int however if the posix standard is to be respected: https://man7.org/linux/man-pages/man3/getopt.3.html

from swift.

Hmm, I thought we got all the instances of char and turned them all into int8_t explicitly to avoid this. but we probably missed the ones in the tests. It does like in this case c should be an int though

from swift.

Yep, I am pushing that change now.

That's now done. This mirror will be updated over night with the fix.
The latest master on gitlab is now using the correct type here to get the return value of getopt().

Fixed in 5fdd4e1.
