; On Thumb1 targets, we have no way to preserve the floating-point registers.
; If all other code is built for Thumb1 or is built soft-float, this is not a
; problem as the FP regs don't need saving. However, if this code is linked
; against ARM code that uses the FP regs, they won't be restored correctly. We
; don't support this use-case, but have no way to prevent it in the compiler.
