To avoid developing headers, wrappers and sources in a disjointed +fashion, LLVM libc employs ground truth files. These files live under the +``spec`` directory and list ground truth corresponding the ISO C standard, the +POSIX extension standard, etc. For example, the path to the ground truth file +for the ISO C standard is ``spec/stdc.td``. Tools like the header generator +(described in the header generation document), docs generator, etc. use the +ground truth files to generate headers, docs etc. |
