From 143d20c16a33e2f08e834b28c23dbea772591ef9 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 24 Oct 2011 16:37:01 -0700 Subject: [PATCH] i965: Move _mesa_ir_link_shader call before device-specific linking _mesa_ir_link_shader needs to be called before cloning the IR tree so that the var->location field for uniforms is set. WARNING: This change breaks several integer division related piglit tests. The tests break because _mesa_ir_link_shader lowers integer division to an RCP followed by a MUL. The fix is to factor out more of the code from ir_to_mesa so that _mesa_ir_link_shader does not need to be called at all by the i965 driver. This will be the subject of several follow-on patches.
