commit 479a849ad606482c3cf67157b77af94ecd450ace Author: Danylo Piliaiev <danylo.piliaiev@gmail.com> Date: Mon Aug 13 18:57:38 2018 +0300 glsl: Avoid calling get_array_element for scalar constants Accessing scalar constant as an array in function call or initializer list triggered assert in get_array_element. Examples: func(0[0]); vec2 t = { 0[0], 0 }; Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107550 Signed-off-by: Danylo Piliaiev <danylo.piliaiev@globallogic.com> Reviewed-by: Tapani Pälli <tapani.palli@intel.com>
