Updated NestedVM toolchain
This repository contains an updated NestedVM toolchain that is suitable for building modern C/C++ applications to pure Java bytecode. The official NestedVM project hosted at nestedvm.ibex.org only supports an old version of GCC (3.3.6). Fortunately, Henry Wertz has made available to use GCC 4.8 and an updated newlib, and this repository includes those patches.
This repo also has some bug fixes by David Ehrmann to NestedVM's
UnixRuntime and the parsing of ELF files generated by GCC 4.8.
In the future, I would like to test and incorporate John Stroy's updates to the NestedVM runtime as well so that a single repository is available with all of these useful changes.
Below are some system-specific build instructions for this repository; pull requests with steps for other environments are certainly welcome.
