           Summary: Crash while launching supertuxkart (svn), "Too many
                    temporaries"
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: gsr.bugs@infernal-iceberg.com

Launching supertuxkart (svn 5892) generates the following when run with
RADEON_DEBUG=vp.

    r300/compiler: compute the final number of temporaries during translation

    And not during the register allocation, which may be skipped for debugging
    purposes. Also the predicate register is now added to the number of temps.
