Sure, I created https://gitlab.winehq.org/wine/wine/-/merge_requests/6179 for
this.

I looked into the problem more: this behavior in Clang is triggered by
'-mrelax-all' which -O0 currently passes, -O1 and higher do not. It was
intended to speed compile times, but doesn't seem to have a noticeable effect
any more.
Sure enough, if you build with -O0 and pass '-mno-relax-all', jmp uses the
shorter form.

Also, Clang 19 will no longer pass '-mrelax-all' for -O0:

This would be a good candidate for the wine-stable branch but those releases
don't seem to be happening this year, I'm not sure why. For the wine stable
port, maybe using '-mno-relax-all' is an option? Or just applying this patch.


Also, does this port set CFLAGS or CROSSCFLAGS when building? Wine uses '-g
-O2' by default, which prevents this bug from showing up.
