From: Jason Ekstrand Date: Tue, 19 Apr 2016 01:57:07 +0000 (-0700) Subject: i965/vec4: Always split uniforms in array_access_to_pull_constants X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=87a4fb516eeebd6be0441db5aeffc705f16bef86;p=mesa.git i965/vec4: Always split uniforms in array_access_to_pull_constants Normally, we split uniforms at the end but in Vulkan, we bail because we don't want pull constants. However, we still need them split because pack_uniforms relies on it. I really don't like this patch not because it doesn't work (it does) but because now that we're using MOV_INDIRECT, uniform numbers and sizes don't really matter anymore. In the FS backend, uniform splitting and packing is handled all at once (actual re-assignment of locations happens later) and we really should do it that way in vec4 eventually as well.
