porting to another jvm/jit

[Joseph Wenninger]

Hi

I'm porting a jvm/jit for a university project to the gnu classpath,
since it is nearly impossible to support the sun jre, if you can't sign
the sun community license, and  therefor don't have the sun-namespaces
sources.

I have done a quick hack for testing purposes, but how would I cleanly
integrate the classpath? My question is, how other jvm developers cope
with the the VM*.c files ? Do they have to be in the classpath
hierarchy, or can I somehow create a static classpath lib and than link
that one against my own, which contains the VM specific implementations
?



Off-topic:
By the way, we would like to support jdk 1.2 class files (major 45,
minor 3). I tried to compile the classpath with jikes -source 1.2
-target 1.2, but it looks like jikes 1.18 doesn't really work with that.
Did anybody try that ? Is there another usable compiler for jre 1.2
compatible class files ?  With jikes I get wrong
[Field|Method|InterfaceMethod]Ref infos structures for many classes,
they point into the constant pool to array constants instead of object
constants. According to my knowledge that's wrong.
Could it be a problem of how the classpath is compiled ?




I'm using the 0.06 tarball

Thanks in advance for any information/help

Kind regards
