From cd9058fae3eddaa0e88cd3557684700852f86a5a Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 15 Apr 2015 02:16:47 -0700 Subject: [PATCH] i965: Make shader_time store names/ids instead of referencing shaders. Jason noticed that shader_time was bumping the reference count on the gl_shader_program and gl_program structures, in code called during compilation. Not only were these never unreferenced, but it meant fragment shaders might be referenced twice (SIMD8 and SIMD16)...or only once. We don't actually need the programs. We just need their numeric ID and their language (GLSL/ARB/FF) or KHR_debug label. If there's a label, we have to strdup it since the underlying program could be deleted. To be fair, we're not exactly cleaning that up either, but we at least ralloc it out of the shader_time arrays, so if we ever bother cleaning those up, they'll go away properly.
