At least GCC 4.7.0 with -O0 would create (unnecessary) +// .gcc_exception_table call-site table entries around all other calls in this +// function that can throw, leading to std::terminate if the asm call throws an +// exception and the unwinding C++ personality routine finds the unexpected hole +// in the .gcc_exception_table. Therefore, make sure this function explicitly +// only calls nothrow-functions (so GCC 4.7.0 with -O0 happens to not create a +// .gcc_exception_table section at all for this function).
