Hi all,
I'm trying to understand how V8 engine compiles and execute JavaScript
events. I used GDB to track the function call path when handling an event
and it look like this.
#0 v8::internal::Logger::TimerEvent (this=<optimized out>, se=<optimized
out>, name=<optimized out>) at ../../v8/src/log.cc:866
#1 0x00007f0cfcb23b39 in TimerEventScope (this=<optimized out>,
isolate=<optimized out>) at ../../v8/src/log.h:354
#2 v8::Function::Call (this=<optimized out>, context=..., recv=...,
argc=<optimized out>, argv=<optimized out>) at ../../v8/src/api.cc:5094
#3 0x00007f0cf18daa0b in blink::V8ScriptRunner::callFunction
(function=..., context=0x201b099829d0, receiver=..., argc=1,
args=0x7fffe9e1cea0,
isolate=0x2def318c6020) at ../../third_party/WebKit/Source/bindings/core
/v8/V8ScriptRunner.cpp:658
#4 0x00007f0cf18a1c26 in blink::V8EventListener::callListenerFunction
(this=0xe9381bfbea0, scriptState=0x37fa7244c710, jsEvent=..., event=
0x36f97e2ba60) at ../../third_party/WebKit/Source/bindings/core/v8/
V8EventListener.cpp:112
#5 0x00007f0cf1887b16 in
blink::V8AbstractEventListener::invokeEventHandler (this=0xe9381bfbea0,
scriptState=0x37fa7244c710,
event=0x36f97e2ba60, jsEvent=...) at ../../third_party/WebKit/Source/
bindings/core/v8/V8AbstractEventListener.cpp:142
#6 0x00007f0cf188787f in blink::V8AbstractEventListener::handleEvent

#9 0x00007f0cf211b7cb in blink::EventTarget::fireEventListeners

at ../../third_party/WebKit/Source/core/events/EventTarget.cpp:56
I tried to read the source code to find out where does V8 compiles the
JavaScript, but unfortunately, I could not find it.
It would be really helpful if someone can explain the process to me, or let
me know which files(functions) I should read.
Best regards,
