Description Mark Hahnenberg 2013-07-19 14:55:51 PDT
This causes the CallFrame's bytecodeOffset to not be properly set when we enter, e.g., cti_optimize from an op_enter.
Comment 1 Mark Hahnenberg 2013-07-19 14:56:45 PDT
This isn't currently a big deal since cti_optimize takes the bytecode offset as its argument, but it will be important for bytecode-liveness-based JSStack scans for GC.
