* 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.
