Subject: [lsan] When necessary, define LSan suppression for pthread_exit.
X-Git-Tag: llvmorg-5.0.0-rc1~6717
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7ca80051b9f1dc6b74edef1b7d860f586c2f383a;p=platform%2Fupstream%2Fllvm.git

[lsan] When necessary, define LSan suppression for pthread_exit.

Summary:
Generalize already defined LSan suppression for the leak on
pthread_exit, some envs do not have the entire call stack symbolized,
so we have to be less specific.
