I am a Computer Science major, and I am currently working on V8 for a
course project. The aim of the project is to gain access in javascript
manipulation to create the AST and machine-language I have finished the
build process and have started with some of my own instrumentation. I am
not a contributor.
While putting some human understandable logging inside v8, I have put some
c++ code to log from inside the v8 to get the hiddenclass manipulation. My
code snipet in log.h under Logger class ->
// ==== User Defined Logging. ====
static Logger& logger(); //Singleton Object
void logEventName(const char* name);
void enterLog(const char* name);
void exitLog(const char* name);
While I am trying to use these functions in side
1. src/ia32/lithium-codegen-ia32.cc
2. src/ia32/full-codegen-ia32.cc
3. src/ia32/code-stubs-ia32.cc
they are compiling good but I am getting error in src/mksnapshot.cc.
Error :::

It looks like a linking error with the new function. I am using them
through namespace.
Code-usage:::
v8::internal::Logger::logger().logEventName("FullCodeGenerator::EmitInlineSmiBinaryOp");
Logger::logger().logEventName("FullCodeGenerator::EmitInlineSmiBinaryOp");
Some help will be appreciated to move through mksnapshot.
Or is there any better or inbuild way to log except the d8 shell flags that
also be a good help.
Thanks,
