Hi,
Moth is the portable interpreter that will be used instead of the just-in-time compiler if your platform doesn't support it. It should be chosen automatically for you according to the #ifdefs in qv4global_p.h.
So if you have qtbase compiling, then qml should also work. If you want things to run faster, then you will have to port the JIT.

Subject: [Development] V4 porting
Hi!
I want to port v4 engine to the new platform. The platform is Linux OS and new processor. The processor looks like intel itanium. It is VLIW and EPIC.
I have a c++/c compilers for the new architecture.
I want to design qt quic qml application for the new platform. As a can see in code, I need v4vm backend for this purpose.
I'm see this:
case use_moth: {
QV4::EvalISelFactory* iSelFactory = 0;
if (mode == use_moth) {
iSelFactory = new QV4::Moth::ISelFactory;
#ifdef V4_ENABLE_JIT
} else {
iSelFactory = new QV4::JIT::ISelFactory;
#endif // V4_ENABLE_JIT
}
QV4::ExecutionEngine vm(iSelFactory);
QV4::Scope scope(&vm);
QV4::ScopedContext ctx(scope, vm.rootContext());
As I understand v4vm has two backends - Moth and Masm.
What is Moth?
