From 56495080ed910c8fb7cd02aa5e3b14e0fb823c6d Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Tue, 24 Jan 2017 11:49:40 +0100 Subject: spirv: handle gl_SampleMask SPIR-V maps both gl_SampleMask and gl_SampleMaskIn to the same builtin (SampleMask). The only way to tell which one we are dealing with is to check if it is an input or an output.
