From c63a1db81f56cc2021fe1fb2411c327f720b0e09 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 5 Jul 2010 22:33:35 -0700 Subject: [PATCH] ir_constant_expression: Initialize all components of constant data to 0. This is probably just a good idea, and will come in useful when implementing things like matrix multiplication. --- src/glsl/ir_constant_expression.cpp | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/glsl/ir_constant_expression.cpp b/src/glsl/ir_constant_expression.cpp index 548217cddd9..1b81017698e 100644 --- a/src/glsl/ir_constant_expression.cpp +++ b/src/glsl/ir_constant_expression.cpp @@ -133,6 +133,8 @@ ir_constant_visitor::visit(ir_expression *ir) unsigned int operand, c; ir_constant_data data; + memset(&data, 0, sizeof(data)); + for (operand = 0; operand < ir->get_num_operands(); operand++) { op[operand] = ir->operands[operand]->constant_expression_value(); if (!op[operand]) -- 2.30.2
