Subject: i965/wm: use binding size for ubo/ssbo when automatic size is unset
X-Git-Tag: upstream/17.1.0~13450
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=14f21f53d50ecd6e2803b2326a90e93aceacfe24;p=platform%2Fupstream%2Fmesa.git

i965/wm: use binding size for ubo/ssbo when automatic size is unset

This fixes the same tests that commit 8cf2e892f was attempting to fix:

ES31-CTS.shader_storage_buffer_object.advanced-unsizedArrayLength-cs-std430-vec-bindrangeOffset
ES31-CTS.shader_storage_buffer_object.advanced-unsizedArrayLength-cs-std430-vec-bindrangeSize

as confirmed by Samuel.
