/*
 * This is used to ensure the compiler did actually allocate the register we
 * asked it for some inline assembly sequences.  Apparently we can't trust
 * the compiler from one version to another so a bit of paranoia won't hurt.
 * This string is meant to be concatenated with the inline asm string and
 * will cause compilation to stop on mismatch.
 * (for details, see gcc PR 15089)
 * For compatibility with clang, we have to specifically take the equivalence
 * of 'r11' <-> 'fp' and 'r12' <-> 'ip' into account as well.
