From 18899d1b8078d2c16b7b3f105e0b39d3ea70a4cc Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Sun, 4 Jan 2015 16:33:37 -0500 Subject: [PATCH] tgsi: track max array per file NOTE IN[] and OUT[] don't need (have?) ArrayID's.. and TEMP[] can optionally have them. So we implicitly assume that ArrayID==0 always exists for each file. This is why array_max[file] is never less than zero. You can tell from indirect_files(_read/written) if the legacy array- id zero was actually used.
