Debugging

Although nOS-V APIs have error checking, it may be useful to build the library with debug symbols enabled in order to pinpoint bugs and issues. To do so, you can use the --enable-debug flag at configure time.

Furthermore, it is also possible to build nOS-V with Address Sanitizer enabled. In this mode, the runtime will assist ASAN by poisoning areas of the shared memory when they are not in use, which may be useful to find memory bugs in user programs that end up corrupting nOS-V memory. To enable ASAN mode, you can use the --enable-asan flag at configure time.
