Right, I missed that and got confused because the method is guarded by "#ifdef COMPILER2" on Sparc.

I changed 'emit_to_interpr_stub()' accordingly and now bail out from the caller if it fails. I also had to adapt the ppc code and the 'emit_trampoline_stub()' method on aarch64.

I left the special handling of -XX:TraceJumps in the Sparc code since JDK-8132344 will fix it.

Here is the new webrev:
