And two more:

3. I assume your change to not use regparm on arm is merely to avoid a
compiler warning?

4. It seems the __ARM_ARCH==7 test is not quite good enough, I get:

/tmp/ccpYAfhg.s:6: Error: selected processor does not support `vpush {d8-d15}'
/tmp/ccpYAfhg.s:11: Error: selected processor does not support `vpop {d8-d15}'

For some gcc targets.

The latter is beyond my abilities to fix, as arm is a minefield of
incompatibilities - any idea how to make the preprocessor test sharper?
