From 40932c1752b0fa918d764e3367f5ab450033304a Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 27 Aug 2010 12:19:30 -0700 Subject: [PATCH] i965: Fix the maximum grf counting in the new FS backend. glsl-algebraic-rcp-rsq managed to use 33 registers, and we claimed to only use 32, so the write to g32 would go stomping over the precious g0 of some other thread. --- src/mesa/drivers/dri/i965/brw_fs.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/i965/brw_fs.cpp b/src/mesa/drivers/dri/i965/brw_fs.cpp index f8b06226d79..673a31c1dd6 100644 --- a/src/mesa/drivers/dri/i965/brw_fs.cpp +++ b/src/mesa/drivers/dri/i965/brw_fs.cpp @@ -1357,7 +1357,7 @@ fs_visitor::assign_regs() last_grf = MAX2(last_grf, inst->src[1].hw_reg); } - this->grf_used = last_grf; + this->grf_used = last_grf + 1; } static struct brw_reg brw_reg_from_fs_reg(fs_reg *reg) -- 2.30.2
