The ground truth of standards
|
||
|
|
=============================
|
||
|
|
|
||
|
|
Like any modern libc, LLVM libc also supports a wide number of standards and
|
||
|
|
extensions. 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.
