From: Rob Clark Date: Tue, 5 Dec 2017 14:53:56 +0000 (-0500) Subject: mesa/st: move cloning of NIR shader for compute X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fd6a96635e2008d152f4bd9836a94cdaf08fb8d2;p=mesa.git mesa/st: move cloning of NIR shader for compute Since in the NIR case, driver takes ownership of the NIR shader, we need to clone what is passed to the driver. Normally this is done as part of creating the shader variant (where is clone is anyways needed). But compute shaders have no variants, so we were cloning earlier. The problem is that after the NIR linking optimizations, we ended up cloning *before* all the lowering passes where done. So move this into st_get_cp_variant(), to make compute shaders work more like other shader stages.
