IMHO, if PR56788 was fixed, you wouldn't have this issue, and if PR56788
doesn't get fixed, I'll post a patch to remove _mm_frcz_sd and the
associated builtin, which would solve your issue as well.


I agree. Then I will wait until your patch is merged to the trunk,
otherwise my patch could not pass the test.

It seems that I was wrong in the PR (I can't remember where I read thatmisleading info at the time), but Uros seems to be handling it just fine:-)
