I've been working on a tool to generate a trace of JavaScript executions, built on JavaScriptCore. I'm trying to log calls to all functions and their arguments. To do this, I've instrumented the op_call and op_call_varargs bytecodes in Interpreter.cpp.
The problem I'm having is that if someone calls a native/host function through apply, I don't see the call. For example, the call: string.fromCharCode.apply(null, [65, 66, 67]); Doesn't seem to correspond to an op_call or op_call_varargs, so I'm wondering how this is handled in JavaScriptCore, what kind of bytecodes generated, and if somebody has any idea what I could do to log the "unseen" calls to native functions, short of instrumenting every native function in WebKit. -- View this message in context: http://old.nabble.com/Bytecode-Sequence-for-function.apply%28%29-tp28623075p28623075.html Sent from the Webkit mailing list archive at Nabble.com. _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
