Restart opcodes set the resume_flag to 1, resume_offset to the next opcode address and then leave the inner run-loop. interpreter.c:runops_int() then restarts a possibly different run-loop on the resume offset again. This is done for changing run loops, e.g. to turn on tracing for some piece of code. > Also, why does the find_global op use it? I couldn't find it explained > anywhere. That's an left over experiment from early tests with throwing exceptions. It isn't necessary anymore. An opcode that may throw a restartable exception has to be a branch op though, so goto ADDRESS(next) would be correct. I'll fix that - thanks for pointing me at that. > Also, on a vaguely related topic, in "Parrot_jit_cpcf_op", what does > "cpcf" stand for? Change Program Control Flow or such. > JEff leo
