- There's no clear need to disable frame pointers if this feature is used, remove this directive. - The 'top' and 'base' terms are reversed. The 'base' is the high address of the stack. The top is the lowest address, where we cannot push further down. Fixup member and offset names to correspond to how these terms are used in hardware documentation. - Use correct pointers for stack top location - Fatal exceptions now go through _NanoFatalErrorHandler to report the faulting ip and thread.
