From 52b68375aeaa1ff6bca48eb833176d3498aa48f7 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 2 Dec 2015 00:38:22 -0500 Subject: [PATCH] nv50/ir: make sure entire graph is reachable The algorithm expects the entire CFG to be reachable, so make sure that we hit every node. Otherwise we will end up with uninitialized data, memory corruption, etc. Signed-off-by: Ilia Mirkin --- src/gallium/drivers/nouveau/codegen/nv50_ir_ssa.cpp | 1 + 1 file changed, 1 insertion(+) diff --git a/src/gallium/drivers/nouveau/codegen/nv50_ir_ssa.cpp b/src/gallium/drivers/nouveau/codegen/nv50_ir_ssa.cpp index 2e432349f24..9ea1065b806 100644 --- a/src/gallium/drivers/nouveau/codegen/nv50_ir_ssa.cpp +++ b/src/gallium/drivers/nouveau/codegen/nv50_ir_ssa.cpp @@ -87,6 +87,7 @@ DominatorTree::DominatorTree(Graph *cfgraph) : cfg(cfgraph), LABEL(i) = i; SEMI(i) = ANCESTOR(i) = -1; } + assert(i == count); build(); -- 2.30.2
