This series of patches adds some simple improvements to the way perf stat handles PMUs that have multiple instances by:
1. Adding glob-like matching in addition to the prefix-based matching introduced previously (patch 1). 2. Adding the ability to recover the PMU names when printing the events separately with the --no-merge option (patch 2). 3. Restoring auto-merge for events created by prefix or glob-like match (patch 3). Note that this still keeps the behavior that disables auto-merging of legacy symbolic events (e.g. cycles). V3: - Consolidated prefix and glob matching into a single glob match with a trailing * to maintain prefix matching and have more consistent behavior. E.g., all of these match all the uncore_imc PMUs: imc, imc*, *imc, *imc* V2: - Updated the documentation to explain prefix and glob matching of PMU names, and event auto-merging. - Added sample output to the third patch.
