[Mesa-dev] [PATCH 1/2] radv: get correct offset into LDS for indexed vars.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This seems more correct to me, since if we have an array
of floats they'll be vec4 aligned, and if we do af[2],
we want the const index to increase by 2 slots in the non
compact case.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105464
Fixes: 94f9591995 (radv/ac: add support for TCS/TES inputs/outputs.)
