[PATCH v11 00/14] TCG code quality tracking

[Fei Wu]

This patch series were done by Vanderson and Alex originally in 2019, I
(Fei Wu) rebased them on latest upstream from:
    https://github.com/stsquad/qemu/tree/tcg/tbstats-and-perf-v10
and send out this review per Alex's request, I will continue to address
any future review comments here. As it's been a very long time and there
are lots of conflicts during rebase, it's my fault if I introduce any
problems during the process.

Alex in his v10 series has addressed part of v9 comments:
   https://www.mail-archive.com/qemu-devel@nongnu.org/msg650258.html
and I tried to figure out some others. It looks to me not all of v9
comments had made complete agreement and I didn't join that discussion
then, so please comment to this series and I will fix them up if
necessary.


Alex Bennée (5):
  accel/tcg: move profiler dev_time to tb_stats
  accel/tcg: convert profiling of restore operations to TBStats
  accel/tcg: convert profiling of code generation to TBStats
  tb-stats: reset the tracked TBs on a tb_flush
  configure: remove the final bits of --profiler support

Vanderson M. do Rosario (9):
  accel/tcg: introduce TBStatistics structure
  accel: collecting TB execution count
  accel: collecting JIT statistics
  accel: replacing part of CONFIG_PROFILER with TBStats
  accel: adding TB_JIT_TIME and full replacing CONFIG_PROFILER
  debug: add -d tb_stats to control TBStatistics collection:
  monitor: adding tb_stats hmp command
  Adding info [tb-list|tb] commands to HMP (WIP)
  tb-stats: dump hot TBs at the end of the execution
