Thanks for your feedback. I've added additional check to dyngen.c, which checks that function has either save; in the beginning and ret; restore; in the end, or ends in retl; nop;. That allowed me to get past the arm target build failure. Now it fails (during dyngen check) on ppc target, the culprit is the following function:

Just keep the instruction after retl, if it's not a nop. Stack adjustments could be combined someplace, but that's a problem with all architectures, not just sparc.

That is:

should become:

In some cases there is just one instruction after retl with nothing before it.
