[Openmp-commits] [PATCH] D35912: Fix implementation of OMP_THREAD_LIMIT

[Terry Wilmarth via Phabricator via Openmp-commits]

tlwilmar created this revision.

This change fixes the implementation of OMP_THREAD_LIMIT.  The implementation of this previously was not restricted to a contention group (but it should be, according to the spec), and this is fixed here. A field is added to root thread to store a counter of the threads in the contention group.  An extra check is added when reserving threads for a parallel region that checks this variable and compares to threadlimit-var, which is implemented as a new global variable, kmp_cg_max_nth.  Associated settings changes were also made, and clean up of comments that referred to OMP_THREAD_LIMIT, but should refer to the new KMP_DEVICE_THREAD_LIMIT (added in an earlier patch).
