Should this be MarkAsCall()? I can't see how caller-saved registers are
preserved across the call into the C library.

[Sven Panne, 2013/12/16 13:30:28]

Good point, this problem is in the other platform ports, too. :-/ I'll upload a
new patch set with fixed DoMathLogs. It's a pity that MarkAsCall is more than is
actually needed, but we don't have a way to express "save caller-saved registers
across this". :-(
