From 3603fdcebfa25e2217f1dbfb0a99261be3e84b02 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 5 Jun 2012 15:58:41 -0700 Subject: glsl: Hook up loop_variable_state destructor to plug a memory leak. While ~loop_state() is already freeing the loop_variable_state objects via ralloc_free(this->mem_ctx), the ~loop_variable_state() destructor was never getting called, so the hash table inside loop_variable_state was never getting destroyed. Fixes a memory leak in any shader with loops. NOTE: This is a candidate for stable release branches.
