3 Replacing OpenMP runtime call <call> with <value>.
4 ====================================================================
6 This optimization remark indicates that analysis determined an OpenMP runtime
7 calls can be replaced with a constant value. This can occur when an OpenMP
8 runtime call that queried some internal state was found to always return a
9 single value after analysis.
14 This optimization will trigger for most target regions to simplify the runtime
15 once certain constants are known. This will trigger for internal runtime
16 functions so it requires enabling verbose remarks with
17 `-openmp-opt-verbose-remarks`.
