            Bug ID: 38365
           Summary: [AArch64][GlobalISel] Never fall back on CTMark or
                    benchmarks (Darwin)
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: GlobalISel
          Assignee: unassignedbugs at nondot.org
          Reporter: aemerson at apple.com
                CC: llvm-bugs at lists.llvm.org

Two reasons for this, one is for general GlobalISel support completeness.

The other main motivation is for runtime performance work. We need to ensure
that we don’t fall back on the benchmarks. If we don’t do this we’ll end up
looking better than we really are at the beginning since we fall back a lot and
SDISel runs with optimizations.
