From 82691f12931a022560f8054c8c8e240cd6b2fff4 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 10 Jul 2012 16:26:33 -0700 Subject: [PATCH] glsl: Change loop_analysis to not look like a resource leak Previously the loop_state was allocated in the loop_analysis constructor, but not freed in the (nonexistent) destructor. Moving the allocation of the loop_state makes this code appear less sketchy. Either way, there is no actual leak. The loop_state is freed by the single caller of analyze_loop_variables.
