From 5b27b63de64167a84a03d820550e56c4b7bbc69d Mon Sep 17 00:00:00 2001 From: Vadim Girlin Date: Sat, 5 Nov 2011 08:48:02 +0400 Subject: r600g: precalculate semantic indices for SPI setup There is no need to duplicate semantic mapping which is done in hw, so get rid of r600_find_vs_semantic_index. TGSI name/sid pair is mapped to the 8-bit semantic index for SPI.
