            Bug ID: 97004
           Summary: [nvptx] __int128 initializer incorrect
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

Consider this code from c-c++-common/spec-barrier-1.c:
...
#ifdef __SIZEOF_INT128__
__int128 g = 9;
#endif
...

We seem to be generating:
...
// BEGIN GLOBAL VAR DEF: g
.visible .global .align 8 .u64 g[2] =
{9,9 };
...
