All,
I'd like to start interface design discussions. Probably the simplest
interface to start with is the API between the classloader and the
JIT/interpreter. Another reason to start with this interface is
because Harmony will need to be able to parse a *.class file before we
do much of anything else.
I have been looking at our current VM implementation which derives
from a research project called ORP. Roughly, the major categories in
the classloader/jit interface are:
- register JIT callbacks (e.g., notify the jit when a given method is
overridden)
- class info (e.g., what is the superclass, which package…)
- method info (e.g., exception info, get_max_stack, pointer to start
of bytecode…)
- field info
- resolution (e.g., find the hard address for a static in a
yet-to-be-loaded class)
- access flags for Class, Field, Method
I'd like to see harmony-dev develop detailed APIs for the above. I
think we should be able to do this within 1-2 months.
Thoughts?
Where is code we can start examining? What do the the java-on-java
implementations do?
