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. | |
