Bug ID: 380350
Summary: RFE: --trace-fork-join in helgrind mode
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: helgrind
Assignee: jsew...@acm.org
Reporter: m...@klomp.org
Target Milestone: ---
This was reported in the fedora bug tracker:
https://bugzilla.redhat.com/show_bug.cgi?id=1455657
When using helgrind, it would be nice to be able to correlate thread lifecycle
events with a program's logs & valgrind reports. drd already has a
--trace-fork-join=yes option; please consider activating same for
--tool=helgrind.
This looks simple enough to implement in the same way drd does.
helgrind already has hooks for track_pre_thread_ll_create and
track_pre_thread_first_insn. helgrind also intercepts pthreadZujoin
(pthread_join) and generates a POST_THREAD_JOIN client request which is handled
in evh__HG_PTHREAD_JOIN_POST. Which seem to be all the places where the
trace_msgs need to be added.
In the track_pre_thread_ll_create thread_post_join pre_thread_create
post_thread_create
