[libc][docs] stub out assert, errno, and locale These were the remaining c89 library headers (besides string.h and stdlib.h; I will split strings.rst in a follow up commit). The macro support detection in docgen doesn't quite work for some of these headers. Add the stubs for these headers for now, and fix up docgen later. See the "NIST publication": Link: https://www.open-std.org/jtc1/sc22/wg14/www/projects.html
libc Documentation ================== The libc documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure libc with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DLIBC_INCLUDE_DOCS=ON After configuring libc with these options the make rule `docs-libc-html` should be available.
