Hi all,
Greetings. New to this list, and to MacRuby. I was just skimming over the
source code from trunk, but wasn't able to find a document that describes the
current design of Roxor. I only found requirements, build instructions, coding
styles and the like.
The thing I find very confusing is that in vm.cpp, RoxorCore::RoxorCore(),
there's a call to ee->DisableLazyCompilation(). This disables LLVM JIT's lazy
compilation. Is it the case that Roxor compiles every method called by the
toplevel script? Or how is Roxor feeding stuff into the JIT?
It seems to me that in main.cpp, main() calls ruby_options(), where the whole
source file gets parsed into MRI's Ruby AST. That AST is supposed to go into
RoxorCompiler::compile_main_method(), and out comes LLVM IR. And then after
optimizations passes, GETCORE()->compile() puts the JIT in action, turns LLVM
IR into native code, and then invoke the IMP. I must have missed
something...but if Roxor JIT compiles a method upon first invocation, where is
this behavior implemented.
Any pointers to documents, blog posts or mails would be truely appreciated.
Thanks in advance,
Raven
