[cp-patches] [Patch] support for direct buffers

[Michael Koch]

Hi list,


I have finally finished support for direct byte buffers in GNU
classpath. The attached patch moves the native methods to a new VM class
called VMDirectByteBuffer and implements the native methods.

To store pointers I use two different classes for 32-bit and 64-bit
archs to make pointer conversion more easy. This trick was stollen from
libxmlj. Thanks to Chris Burdess for pointing me to it.

The patch was tested on x86. I have no 64-bit arch to test this. I have
written some mauve testcases for this but they are not commited yet.

What do people think about this patch ?
