Peter Maydell 332d584970 softfloat: Revert and reimplement remaining parts of b645bb4885 and 5a6932d51d ... Revert the parts of commits b645bb4885 and 5a6932d51d which are still in the codebase and under a SoftFloat-2b license. Reimplement support for architectures where the most significant bit in the mantissa is 1 for a signaling NaN rather than a quiet NaN, by adding handling for SNAN_BIT_IS_ONE being set to the functions which test values for NaN-ness. This includes restoring the bugfixes lost in the reversion where some of the float*_is_quiet_nan() functions were returning true for both signaling and quiet NaNs. [This is a mechanical squashing together of two separate "revert" and "reimplement" patches.] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Message-id: 1421073508-23909-4-git-send-email-peter.maydell@linaro.org		2015-01-29 16:45:33 +00:00
