slowproduct build

Yes that’s what I want.

Yesterday I was using gdb to step into the interpreter generation code to see what’s generated for a particular routine for MethodHandles. The debug build contains a LOT of runtime verification code in the generated code and I couldn’t figure out what’s happening. The product build just generates 10 instructions.

Thanks
