I'm in the process of writing a program to analyze traces of JavaScript code. This involves logging events that occur in the interpreter. Currently, I'm trying to just log function calls and property accesses. However, I'm unsure exactly how to go about getting the names (identifiers) associated with functions (and properties). I wrote the following piece of code just to test things out, which I inserted in Interpreter.cpp, in the definition of the op_call opcode, after the "vPC = newCodeBlock->instructions().begin();" line: JSGlobalObject* globalObject = callFrame->scopeChain()->globalObject; printf("Function call: %s\n", asFunction(v)->name(globalObject->globalExec()).ascii()); printf("%s\n", newCodeBlock->ownerExecutable()->sourceURL().ascii()); printf("%i\n", newCodeBlock->ownerExecutable()->lineNo()); My goal was to report the name of the function being called each time an op_call is executed. However, this does not report the function names correctly. My guess is that I'm passing the wrong value to InternalFunction::name(). Can anyone tell me what I'm doing wrong here? I'm rather unfamiliar with the WebKit code. -- View this message in context: http://old.nabble.com/Function---Property-Names-tp28394250p28394250.html Sent from the Webkit mailing list archive at Nabble.com.
