FWIW, this is failing with Clang 15 for me:
s390x/ex.c:81:4: error: expected absolute expression
" .if (1b - 0b) != (3b - 2b)\n"
^
<inline asm>:12:6: note: instantiated into assembly here
.if (1b - 0b) != (3b - 2b)
Seems gcc is smarter here than clang.
Yeah, the assembler from clang is quite a bit behind on s390x ... in the
past I was only able to compile the k-u-t with Clang when using the
"-no-integrated-as" option ... but at least in the most recent version it
seems to have caught up now enough to be very close to compile it with the
built-in assembler, so it would be great to get this problem here fixed
somehow, too...
Bringing up another option: Can we maybe guard this section from Clang so we still have the assertion when compiling with GCC?
I considered this, but only from the asm, where I don't think it's possible.
But putting #ifndef __clang__ around it works. Until you compile with gcc and assemble with clang.
Not something we need to care about IMO.
Right. So if the #ifndef works, let's go with that! Nico, could you fix it
up in the pull request?
Thanks,
Thomas
