Sorry, I am not familiar with qemu internals enough to understand that. It
currently fails the build in the sanity check implemented in dyngen.c. We
figured out so far that there might be two valid cases:
save;...ret;restore;
and ....;retl;nop;. Are you saying that the function ending in
retl;some_insn; is valid as well and the check has to be modified yet again
to accomodate this (third) case?
Yes, though the second case can be seen a special case of the third.
Right. I've modified the check and now it goes further in the build. The
next failure I'm hitting is:

Looks like there is no cpu_get_real_ticks() function implementation for
sparc. There is an old message on qemu-devel discussing this issue [0].
It looks like this function is fairly easy to implement by reading the
%tick register in machines compliant with SPARC v9 architecture (Ultra1
or better), however the implementation for v8 architecture (and we are
building binaries for v8 in Debian) does not look so simple. I'd
appreciate any opinions or hints on this matter.
