            Bug ID: 39038
           Summary: [llvm-exegesis] Exploration of MCInstr predicates
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

Right now we can check if an instruction supports the zero-idiom with:

```
echo 'vxorps %ymm0, %ymm0, %y^C| ./bin/llvm-exegesis -mode=uops
-snippets-file=-
```

It would be nice if the llvm-exegesis SnippetGenerator could generate
configurations for all MCInstPredicates in the SchedModel to discover which
instructions support the zero idiom.
