Not sure what you're asking.  If you want I can resend the analysis.
Basically the clobbers are bogus and the asm itself uses too many
registers to be safely compiled.

This is the exact code we're using as an example of the asm problems
that we need to address.

The problem is that many linux asms use a invalid construct, so
the error has to be conditional so that the linux folks have the
opportunity to transition away from the bogus way they've been
writing asms.
