I want to dump each piece of dynamically generated code. Meanwhile, if its
corresponding bytecode is available, I also dump the bytecode and record
the starting line number of the script code (i.e. recording the script name
and the line number). For this purpose, i inserted code snippets in
functions which would invoke "factory->NewCode". The following code is what
i inserted into "CodeGenerator::GenerateCode()". However, my code can only
successfully dump jit'ed code, but cannot dump bytecodes and record the
script information. How can I solve this problem? Thanks!
Bye the way, i am working on Version 6.0.99, the latest commit is
71c1795aea7573672dd264568357c0f49afc7321.
