Summary: [r300g] Dynamic branching 3 demo does not run Product: Mesa Version: git Platform: Other URL: http://www.humus.name/index.php?page=3D&ID=67 OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: sa@whiz.se
I'm filing this just in case it's of interest for those hacking shaders on r300. Humus DynamicBranching3 demo does not run:
Note: 'for (i ... )' body is too large/complex to unroll Fragment program using varying vars not written by vertex shader
For reference, this demo does work with the i965 driver.
