After the recent GNU linker script changes, the following warning is emitted many times during the OVMF build: BFD: <...>: warning: Empty loadable segment detected, is this intentional ? This is caused by the fact that, now that the section layout has changed somewhat, the .eh_frame section is assigned an ELF segment of its own, which ends up with no contents at all after we strip the .eh_frame section from the output. (Note that the program headers that contain the segment information are completely irrelevant to us since the PE/COFF conversion does not rely on them.) Since we only retain the .eh_frame data for external debugging, and not for things like stack unwinding or generating backtraces at runtime, we can remedy the situation by passing -fno-asynchronous-unwind-tables on the GCC command line. This option instructs the compiler to emit the unwind data into a debug section called .debug_frame instead of into .eh_frame.

This directory contains the template files for the next generation of the EDK II Build infrastructure. These files will be copied into the WORKSPACE's Conf directory if and only if the target files do not exist. These files may be updated frequently. The XMLSchema directory contains the EDK II Packaging XML definitions. The schema may change in the future. It differs somewhat from the early versions of the XML Schema.
