From a0029021681a61d01e5a4603a32cf1bfdfca1d43 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 4 Dec 2012 15:09:39 -0800 Subject: mesa: Fix GL_SHADER_BINARY_FORMATS query There were two bugs here. First, this and several other queries were not available in a desktop GL context with GL_ARB_ES2_compatibility. Second, GL_NUM_SHADER_BINARY_FORMATS returns zero, but GL_SHADER_BINARY_FORMATS writes one element of data to the buffer. If NUM is zero, no data should be written. Fixes piglit test 'arb_get_program_binary-overrun shader'. NOTE: This is a candidate for stable release branches.
