From 5d6d260833e374404f80d1c36bc0e1854369a069 Mon Sep 17 00:00:00 2001 From: Axel Davy Date: Wed, 26 Nov 2014 20:52:53 +0100 Subject: [PATCH] st/nine: sm1_declusage_to_tgsi, do not restrict indices with TGSI_SEMANTIC_GENERIC MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit With sm3, you can declare an input/output with an usage and an usage index. Nine code hardcodes the translation usage/index to a corresponding TGSI code. The translation was limited to a few usage/index combinations that were corresponding to most of the needs of games, but some games did not work. This patch rewrites that Nine code to map all possible usage/index combination to TGSI code. The index associated to TGSI_SEMANTIC_GENERIC doesn't need to be low for good performance, as the old code was supposing, and is not particularly bounded (it's UINT16). Given the index is BYTE, we can map all combinations.
