From 650386a7e80c77853ccd5cc833420e2485d62eec Mon Sep 17 00:00:00 2001 From: "Eunki, Hong" Date: Tue, 21 Nov 2023 15:28:04 +0900 Subject: [PATCH] [Tizen] Ensure to check GLES::ShaderImpl when we found GLES:ProgramImpl Previously, We only consider 1 Graphis::Shader per 1 shader codes. But for now, we allow to use multiple Graphics::Shader per 1 shader code, by cache GLES::ShaderImpl system. But we check Graphics::Shader pointer when we found cached ProgramImpl for now. It will make some unneccessary glLinkProgram call when Graphics::Shader cache miss occured. To resolve it, let we cache GLES::Shader wrapper instead of Graphics::Shader. And compare with the pointer of GLES::ShaderImpl.
