JVM Port

JVM Port

[Francis Grolemund]

Hi.  I'm considering doing a port of the GCC compiler to the Java Virtual
Machine - particularly for compiling C code to work on the JVM.  Do you
know of any open projects working on that and if not would you have any
objections to me continuing investigation on that?

Thanks,
Fran Grolemund

Have a look at:

IIRC, it's based on the GCC front end.

This was discussed here almost one year ago:
http://gcc.gnu.org/ml/gcc/2001-02/msg000895.html

As far as I know nobody is working on this.
I can't think of a reason that the Gcc maintainers would object to this.

It's technically possible, but really does not make much technical sense.
If you want to compile C code to work on the JVM, you really need to write
a translator at the appropriate level (e.g. look at JGNAT as an example
of doing this for Ada).
