CompiledStaticCall::emittointerpstub() is compiler independent code. Shouldn’t the call be ciEnv::current()->recordfailure() even if the method is only called from c2 (for now?)? (which is what Dean suggested as well I think)

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

Actually, why not have emittointerpstub() returns an error and bail out from compilation in the caller?

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.

Thanks, Tobias

Roland.
