            Bug ID: 106391
           Summary: Noveau fails to compile when using meson and LLVM
                    without RTTI
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau at lists.freedesktop.org
          Reporter: cogitri at exherbo.org
        QA Contact: nouveau at lists.freedesktop.org

When building mesa without RTTI support nouveau fails to compile because NDBUG
isn't defined by meson. src/gallium/drivers/nouveau/codegen/nv50_ir.cpp has the
following snippet in it:

#ifndef NDEBUG // non-conformant assert, so this is required
  assert(typeid(*i) == typeid(*this));
#endif

which results in:
