From eca8032f20d0970184843d98e2bddb688e94a3a9 Mon Sep 17 00:00:00 2001 From: Caio Marcelo de Oliveira Filho Date: Mon, 5 Aug 2019 16:25:11 -0700 Subject: gallium: Add ARB_gl_spirv support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The PIPE_CAP_GL_SPIRV capability enables ARB_gl_spirv and ARB_spirv_extensions, and will make sure the corresponding SPIR-V capabilities and extensions lists are initialized. The additional PIPE_CAP_GL_SPIRV_VARIABLE_POINTERS capability enables the support for Variable Pointers in SPIR-V shaders. This depends on the driver and is not mandatory for ARB_gl_spirv support. v2: Add a PIPE_CAP for Variable Pointers.
