hi,
adding support for creating event groups based on the way they
are specified on the command line.
This patchset adds the '{}' style grammar to express event group,
allowing so far only the 'event modifier' as group modifier.
v4 changes:
- group modifier updates events modifiers (not overwrite as in v3)
Attached patches:
perf, tool: Add support to parse event group syntax
perf, tool: Add support to update event modifier
perf, tool: Enable grouping logic for parsed events
perf, test: Add automated tests for event group parsing
wbr,
jirka
