Test inter- and intra-stage gl_PerVertex matching rules

Graphics / Mesa 3D Graphics Library / Piglit - Paul Berry [gmail.com] - 8 October 2013 14:21 UTC

These tests verify the following linkage rules, from GLSL 4.10:

1. If multiple shaders using members of a built-in block belonging to the same interface are linked together in the same program, they must all redeclare the built-in block in the same way, as described in section 4.3.7 "Interface Blocks" for interface block matching, or a link error will result.

2. It will also be a link error if some shaders in a program redeclare a specific built-in interface block while another shader in that program does not redeclare that interface block yet still uses a member of that interface block.
