  Hi,

Note there is no ULP change here really - sinf/cosf were never exact in any
implementation and so have always been 1ULP. The testsuite likely focusses
more on round to nearest rather than other rounding modes, so it simply didn't
report the correct ULP for the SSE implementation.

Cheers,
Wilco
