This testsuite consists of a collection of (non-functional) programs snippets to check an RTEMS toolchain consisting of * GCC (libgcc etc.) * binutils * newlib (libc) * RTEMS (librtemscpu + librtemsbsp) for IEEE Std 1003.1-2008 (aka. POSIX[1]) compliance by link-tests. All of these programs are supposed to be compilable without any warning, independently of the configuration being used in any of the components involved. NB: - Using "advanced GCC warning flags" may trigger warnings. Such warnings should be avoided if possible. - These program snippets are not supposed to be functional. - This suite only checks for a subset of POSIX library calls, which are known to have been critical in RTEMS/GCC/newlib interaction at some point in RTEMS/GCC/newlib's history.
