            Bug ID: 51687
           Summary: [llvm-exegesis] Analysis tests should run even without
                    libpfm
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-exegesis
          Assignee: unassignedbugs at nondot.org
          Reporter: llvm-dev at redking.me.uk

The tests in llvm-project\llvm\test\tools\llvm-exegesis\ include a mixture of
tests for all the modes supported by llvm-exegesis (uops, latency,
inverse_throughput and analysis).

Only the first 3 modes require llvm-exegesis to be built with libpfm to
actually investigate the hardware. The analysis mode tests should be run in all
cases where the relevant target is supported.
