If you want to understand how Kaffe's JIT calls C functions, you will
probably want to take a look at the places in kaffe/kaffevm/kaffe.def that
have calls to C functions begin with the characters "softcall". The file
kaffe/kaffevm/jit/icode.c file contains all the "softcall" functions. Each
"softcall" function generates the code to set up the argument list and call
a specific C function from the JIT generated machine language. All these
softcall functions call another function in icode.c, call_soft(), which
generates the actual call in the translated code.

I hope that this helps you with your modifications.
