Hi all!
I am new to V8 project. I am trying to work on crbug.com/v8/6005 (Migrate
v8natives.js). By referencing commit history and the style of the codes and
lots help from cs.chromium.org/chromium/src/v8/, I at least figured out how
to migrate the constants (CL accepted). However, migrating functions is a
lot harder for me.
Things I feel confused about:
- In builtins/builtins-object.cc, functions wrapped by BUILTIN()
sometimes return Handle<Object>, sometimes Handle<JSReceiver>.
- In several commits where JS functions are moved to C++, sometimes
runtime/runtime.h, runtime/runtime-{type}.cc and debug/debug-evaluate.cc
need to be modified as well, but not always.
- How to decide whether to implement the function as C++ builtin or TF
builtin?
It will be great someone can guide me through this. Is there existing
documentation on how V8 codes are organized, how to use certain C++
functions, https://tc39.github.io/ecma262/ and so on?
Thanks in advance.
Regards,
Rong Jie
