Subject: [Bug 42435] New: Suspected loss of varyings between shaders
Date: Mon, 31 Oct 2011 14:40:48 +0000	[thread overview]

             Bug #: 42435
           Summary: Suspected loss of varyings between shaders
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: screwdriver@lxnt.info


Longer description, the test case, screenshots, and core from i965 crash  are
in attached archive.

In short:

I try to draw a 2D screenful of point sprites, emulating an ansi-colored
terminal. Fragment shader receives texture coordinates for the character, its
color and size of graphic in the texture via varyings.

R600g draws a black screen, while llvmpipe and fglrx draw what is supposed to
be drawn. i965 crashes. non-llvm swrast fails to set gl_PointSize. R600c also
draws a black screen.

Drawing varying values themselves I get bogus values for some of them.

Mesa version: 7.12.0~git20111027.0fbc8d30-0ubuntu0sarvatt~natty
