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