From: Alexander Yarygin <yarygin@xxxxxxxxxxxxxxxxxx>
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.
