This patch adds the %m conversion to printf, which prints the strerror(errno). Explanation of why is below, this patch also updates the docs, tests, and build system to accomodate this. The standard for syslog in posix specifies it uses the same format as printf, but adds %m which prints the error message string for the current value of errno. For ease of implementation, it's standard practice for libc implementers to just add %m to printf instead of creating a separate parser for syslog.
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.
