Dear GCC community! I have started a custom libc implementation for the purpose of education. What are the minimum requirements for the library (functions, headers, ...) which one *must* be implemented so GCC can use this library as default? And how should I write the specification file, so that GCC can use this library in the build process from GCC? How to deal with multi architecture support in a custom libc? What are here the requirements? Thanks in advance! Kind regards, Johannes K.
