            Bug ID: 80266
          Assignee: nouveau at lists.freedesktop.org
           Summary: Undefined operation in tgsi_ureg.c left shift of 1 by
                    31 places cannot be represented in type 'int'
          Severity: minor
    Classification: Unclassified
                OS: Linux (All)
          Reporter: zeccav at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 10.2
         Component: Drivers/DRI/nouveau
           Product: Mesa

In tgsi_ureg.c:1498
"if (ureg->vs_inputs[i/32] & (1 << (i%32))) {"
when i==31 then 1 << 31 may be computed.
With gcc option -std=c99 this is wrong because the result cannot be int.

Perhaps the right instruction is
"if (ureg->vs_inputs[i/32] & ((unsigned) 1 << (i%32))) {"
