Thanks to the effort of @RoseZhang03 and @aaryanshukla under the guidance of @michaelrj-google and @amykhuang, we now have newhdrgen and no longer have a dependency on TableGen and thus LLVM in order to start bootstrapping a full build. This PR removes: - LIBC_HDRGEN_EXE; the in tree newhdrgen is the only hdrgen that can be used. - LIBC_USE_NEW_HEADER_GEN; newhdrgen is the default and only option. - LIBC_HDRGEN_ONLY; there is no need to have a distinct build step for old hdrgen. - libc-api-test and libc-api-test-tidy build targets. - Deletes all .td files. It does not rename newhdrgen to just hdrgen. Will follow up with a distinct PR for that. Link: #117209 Link: #117254 Fixes: #117208
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.
