[PATCH] D97901: [SystemZ] Test for infinity in testFPKind().

[Jonas Paulsson via Phabricator via cfe-commits]

jonpa updated this revision to Diff 330753.
jonpa added a comment.

> This "invert" logic doesn't look correct. "isfinite" and "isinf" both need to return false on NaNs. I think you should just drop the invert logic and use a TDC mask of 0xFC0 (zero, normal, or subnormal) to implement "isfinite".

Rebased and updated per review.
