Summary: This patch implements the `fgets`, `getc`, `fgetc`, and `getchar` functions on the GPU. Their implementations are straightforward enough. One thing worth noting is that the implementation of `fgets` will be extremely slow due to the high latency to read a single char. A faster solution would be to make a new RPC call to call `fgets` (due to the special rule that newline or null breaks the stream). But this is left out because performance isn't the primary concern here.
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.
