From 6531ccb7056f80c32a29e07fe05381b0fd6557dc Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Mon, 4 Jan 2016 23:28:52 -0500 Subject: [PATCH] i965: quieten compiler warning about out-of-bounds access gcc 4.9.3 shows the following error: brw_vue_map.c:260:20: warning: array subscript is above array bounds [-Warray-bounds] return brw_names[slot - VARYING_SLOT_MAX]; This is because BRW_VARYING_SLOT_COUNT is a valid value for the enum type. Adding an assert will generate no additional code but will teach the compiler to not complain.
