[LLVMdev] Using StartJnjvmWithJIT from jnjvm.cpp in VMKit

[Gaël Thomas]

Hi,

Basically, generateMain (JavaAOTCompiler.cpp) generate the C main
function when you compile a Java application with the AOT. And
generateMain invokes the main of the Java application, which is fixed
during the compilation: this main class is simply the main method of
the Main-Class of the jar file (or an argument that you give through
the command line when you invoke the AOT compiler). After, at runtime,
when you invoke the main of the Java application, you have to fill the
arguments of the Java application, and they are given through the
command line. To summarize, the main function looks like this:


int main(int argc, char** argv) {
  StartJnjvmWithJIT(argc, argv, "TheMainClassOfTheCompiledApplication");
}

argc and argv are the arguments given at runtime, the main class is
the argument of the AOT compiler.
