From: Alexander Yarygin <[email protected]> Trace events potentially can have a '-' in their trace system name, e.g. kvm on s390 defines kvm-s390:* tracepoints. tools/perf could not parse them, because there was no rule for this: $ sudo ./perf top -e "kvm-s390:*" invalid or unsupported event: 'kvm-s390:*'
This patch allows '-' to be a part of PE_NAME token, so tracepoints with '-' can be parsed by the event_legacy_tracepoint rule. Without the patch, perf will not accept such tracepoints in the -e option.
