Subject: OpenMP Tasks dependencies hash re-sizing fixed.
X-Git-Tag: llvmorg-11-init~5802
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=be29d9285487e1970f0ad070d79d5dfeca345f2e;p=platform%2Fupstream%2Fllvm.git

OpenMP Tasks dependencies hash re-sizing fixed.

Details:
- nconflicts field initialized;
- formatting fix (moved declaration out of the long line);
- count conflicts in new hash as opposed to old one.
