            Bug ID: 107146
           Summary: swr doesn't compile with current LLVM 7.0 snapshots
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/swr
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: bero at lindev.ch
        QA Contact: mesa-dev at lists.freedesktop.org

createInstructionSimplifierPass() has been removed in LLVM. This is used in a
few places in SWR; looks like this can safely be removed because it is always
preceded by createInstructionCombiningPass() which seems to be a superset of
what createInstructionSimplifierPass() used to do.

Fixing this just unmasks another problem though -
Intrinsic::x86_fma_vfmadd_ps_256 is gone. Not sure how to replace that
