A "Java Backend"
...ode to take the place of the system call layer.
The caveat here is that Java has this "private"
but-not-really-in-practice API called sun.misc.Unsafe that can be used
to access native memory. So you can have (I'm paraphrasing, the
method names may not match):
long addr = unsafe.allocateMemory()
unsafe.putInt(addr + 48, 9001);
int val = unsafe.getInt(addr + 48);
etc. You may even get decent performance out of this since JIT
compilers tend to have to optimize these well (they're commonly uses
in the implementation of some popular JDK classes).
But you're right that it wil...

A "Java Backend"
My idea was to create a complete backend treating Java as a normal platform, to enable LLVM to compile programs to Java Bytecode (.class) and Java Archive files (.jar). This could be useful in situations where we need to compile a program for a platform still not natively supported by LLVM.
I don't know if it exists already, I've heard about this "LLJVM" but I don't think it
