Subject: [stage1][PATCH 0/3] __gcov_dump improvements
Date: Fri, 3 Apr 2020 10:06:46 +0200	[thread overview]
Message-ID: <cover.1585901206.git.mliska@suse.cz> (raw)

Hi.

The following mini patch series improves:
- gcov run-time locking is used for user accessible __gcov_dump and __gcov_reset functions
- do not run __gcov_flush in fork, only __gcov_reset is called in child process
- gcov exec* wrappers dump counters and reset only if execv* fails

Patch can bootstrap on x86_64-linux-gnu and survives regression tests. 
I'll install the patch set in next stage1 if there are no objections.

Thanks,
Martin

Martin Liska (3):
  Do locking for __gcov_dump and __gcov_reset as well.
  Use __gcov_dump and __gcov_reset in execv and fork context.
  Remove __gcov_flush.
