Hi, In SelectionDAGISel::SelectAllBasicBlocks if (TM.Options.EnableFastISel) FastIS = TLI->createFastISel(*FuncInfo, LibInfo); followed by if (!FastIS) { LowerArguments(Fn); } else { The above implies that implementing FastIS is optional. In contrast to that, testing whether FastIS is actually been used is done by testing if TM.Options.EnableFastISel...

...balISel always set when GISel is enabled Change meaning of TargetOptions::EnableGlobalISel. The flag was previously set only when a target switched on GlobalISel but it is now always set when the GlobalISel pipeline is enabled. This makes the flag consistent with TargetOptions::EnableFastISel and allows its use in other parts of the compiler to determine when GlobalISel is enabled. The EnableGlobalISel flag had previouly only one use in TargetPassConfig::isGlobalISelAbortEnabled(). The method used its value to determine if GlobalISel was enabled by a target and retu...
