[PATCH] D11793: [compiler-rt] Add SourceLocations for float_cast_overflow data.

[Filipe Cabecinhas via llvm-commits]

Remove undefined behavior (unless I misread the standard) :-)

We could use __builtin_memcpy to avoid the call and get a simple "mov" instruction (on x86), but I'm not sure if that's available for all compilers we support.
Opinions?
