From ca6b3b11af29b93ac73d4ca2677aa6b34837fdfe Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 7 Jan 2020 17:51:03 -0600 Subject: anv: Don't add dynamic state base address to push constants on Gen7 Because Gen7 push constants are already relative to dynamic state base address, they aren't really an address. It's deceptive to return an address from the helper function. Instead, let's leave it as a special-case in the gen7-11 helper; we don't need the helper for code de-duplication for Gen7 anyway.
