From: Dave Airlie Date: Tue, 26 Aug 2014 23:56:14 +0000 (+1000) Subject: tgsi: add support for flt64 constants X-Git-Tag: upstream/17.1.0~20658 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fa43e0443e206740e219d45abefee65bdb2c3ecb;p=platform%2Fupstream%2Fmesa.git tgsi: add support for flt64 constants These act like flt32 except they take up two slots, and you can only add 2 x flt64 constants in one slot. The main reason they are different is we don't want to match half a flt64 constants against a flt32 constant in the matching code, we need to make sure we treat both parts of the flt64 as an single structure.
