[PATCH 0/7] New function and literals for metrics

[Ian Rogers <irogers@google.com>]

Add a test for hyphenated events that are common with Intel's icelake
topdown events.

Try to tidy the existing cputopo code and make it more consistent with
the sysfs ABI. Refactor the #smt_on literal parsing into a general
literal token that we can use for more literals. This is then used for
num_cpus, num_cores, num_dies and num_packages literals that use the
existing topology code. Finally, a source_count function is added
which is used to determine the number of events contributing to an
aggregate event. The intent for these new literals and function is for
them to be used in upcoming metrics.

Ian Rogers (7):
  perf test: Add expr test for events with hyphens
  perf cputopo: Update to use pakage_cpus
  perf cputopo: Match die_siblings to topology ABI name
  perf cputopo: Match thread_siblings to topology ABI name
  perf expr: Add literal values starting with #
  perf expr: Add metric literals for topology.
  perf expr: Add source_count for aggregating events
