From 6e8d04ac3e9074bffe25a1ef9e6b198caaa30385 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 6 Feb 2014 18:21:58 -0700 Subject: [PATCH] mesa: allocate gl_debug_state on demand We don't need to allocate all the state related to GL_ARB_debug_output until some aspect of that extension is actually needed. The sizeof(gl_debug_state) is huge (~285KB on 64-bit systems), not even counting the 54(!) hash tables and lists that it contains. This change reduces the size of gl_context alone from 431KB bytes to 145KB bytes on 64-bit systems and from 277KB bytes to 78KB bytes on 32-bit systems.
