Subject: [X86] Change the rounding mode used when testing the sqrt_round intrinsics.
X-Git-Tag: llvmorg-7.0.0-rc1~1484
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2f7de23bea6324fe366d5e5d2676a8a1f981013a;p=platform%2Fupstream%2Fllvm.git

[X86] Change the rounding mode used when testing the sqrt_round intrinsics.

Using CUR_DIRECTION is not a realistic scenario. That is equivalent to the intrinsic without rounding.
