perf evsel: Add support for synthesized sample type (e11869a0) · Commits · 戴 / test

For reporting purposes, an evsel sample can have a callchain synthesized from AUX area data. Add support for keeping track of synthesized sample types. Note, the recorded sample_type cannot be changed because it is needed to continue to parse events. Signed-off-by:
