The page 55 of The SPARC v8 Architecture Manual describes jump/branch case explicitly: cpu should execute one instruction on the jump target and then branch.
It's not what qemu does!
Don't know how to fix it myself though. Need to persuade the qemu developers to fix it. I seriously doubt that a compiler would use this feature, so Linux&Co are not affected by this bug at all.
