+ static bool classof(const CGOpenMPRuntime *RT) {
+ return RT->getKind() == RK_HOST;
----------------
This is required to cast to the NVPTX runtime in a static function as follows;
CGOpenMPRuntimeNVPTX &RT = cast<CGOpenMPRuntimeNVPTX>(CGM.getOpenMPRuntime());
================
Comment at: lib/CodeGen/CGOpenMPRuntime.h:975
+ bool WithNowait, bool SimpleReduction,
+ OpenMPDirectiveKind ReductionKind);
----------------
NVPTX requires this parameter because the reduction implementation for
'parallel', 'simd', and 'teams' are different. This is required for
correctness and performance.
