`double` should be safe for ARM DWARF EH, though, technically, `long double` is more appropriate of a type definition (the FPU state that is saved should be the widest floating point type).  That would be `long double` (aka FP80 on x86, FP128 on AArch64/PPC, FP64 elsewhere).  This happens to work because ARM uses FP64 irrespective of DWARF or EHABI.
