From: Ilia Mirkin Date: Sat, 9 Apr 2016 17:11:42 +0000 (-0400) Subject: glsl: allow usage of the keyword buffer before GLSL 430 / ESSL 310 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9b5bd20eb2d09e1ec2319b55c83ad7f28b6fefee;p=mesa.git glsl: allow usage of the keyword buffer before GLSL 430 / ESSL 310 The GLSL 4.20 and ESSL 3.00 specs don't list 'buffer' as a reserved keyword. Make the parser ignore it unless GLSL 4.30 / ESSL 3.10 are used, or ARB_shader_storage_buffer_objects is enabled.
