[PATCH v7 0/4] perf: add support for profiling jitted code

2015-09-30 Thread Stephane Eranian
This patch series extends perf record/report/annotate to enable profiling of jitted (just-in-time compiled) code. The current perf tool provides very limited support for profiling jitted code for some runtime environments. But the support is experimental and cannot be used in complex environments.
