[PATCH] D91879: [Flang][OpenMP 4.5] Add semantic check for OpenMP Schedule Clause - chunk size

[Kiran Chandramohan via Phabricator via llvm-commits]

kiranchandramohan added a comment.

I only saw the following one which puts some conditions for using the same assignment of logical iteration numbers to threads for two loops. If these conditions are not met it is just that the implementation can use a different assignment. Are you referring to something else?

"A compliant implementation of the static schedule must ensure that the same assignment of logical iteration numbers to threads will be used in two loop regions if the following conditions are satisfied: 1) both loop regions have the same number of loop iterations, 2) both loop regions have the same value of chunk_size specified, or both loop regions have no chunk_size specified, 3) both loop regions bind to the same parallel region, and 4) neither loop is associated with a SIMD construct. A data dependence between the same logical iterations in two such loops is guaranteed to be satisfied allowing safe use of the nowait clause."
