https://bugs.freedesktop.org/show_bug.cgi?id=94298

Bug ID: 94298 Summary: Missing gl_PerVertex block does not fail SSO Product: Mesa Version: 11.1 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: pavol@klacansky.com QA Contact: dri-devel@lists.freedesktop.org

The spec required declaration of gl_PerVertex block if separate shader objects are used and the variable is written to. Mesa however works regardless its presence.
