efriedma added a comment. Why can't the compiler handle this case itself transparently? According to your description, the interrupt calling convention is different from the normal hard-float AAPCS calling convention: the VFP registers are all callee-save. The compiler knows this; it should be able to insert the appropriate spills itself.
