[PATCH] D157686: [llvm-exegesis] Add error for subprocess and dummy perf counters

[Aiden Grossman via Phabricator via llvm-commits]

aidengrossman added reviewers: courbet, gchatelet, ondrasej.
aidengrossman added a comment.

The plan is to support this configuration at some point (probably soon) as it should be fairly useful in a downstream application I'm working on, but for now we should report a better error message.
