X-Git-Tag: upstream/1.3.5~2^2^2^2~2^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=764b2f056e47178bef81c63c358aee8922a13901;p=platform%2Fupstream%2FVK-GL-CTS.git

Add RISC-V 64 bit support

Android is adding RISC-V support to AOSP, but only for 64-bit RISC-V.
(We've only added the 32-bit constants for completeness, should others
want them.)

Components: Framework, Vulkan, AOSP
