Summary: The ARB_fragment_program subset of ARB_draw_buffers
not implemented
Product: Mesa
Version: git
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: mar...@gmail.com
Hi, I have noticed that the parser for ARB_vertex/fragment_program doesn't
implement ARB_draw_buffers. result.color[n] should be allowed if "OPTION
ARB_draw_buffers;" is specified. However, when I try to use it like this:
> MOV result.color[0], fragment.texcoord[0];
I get this message:
> Compiler Error (pos=46 line=-1): line 3, char 17: error: syntax error,
> unexpected '[', expecting ','
I was looking at the code of the parser, but I don't understand a thing in it.
This bug can be reproduced with:
piglit/arb_color_buffer_float-mrt
softpipe with ARB_color_buffer_float and ARB_texture_float support, which is
required for the piglit test, can be found in this branch:
