◆ trySchedule()

bool llvm::sandboxir::Scheduler::trySchedule ( ArrayRef< Instruction * > Instrs )

Tries to build a schedule that includes all of Instrs scheduled at the same scheduling cycle.

This essentially checks that there are no dependencies among Instrs. This function may involve scheduling intermediate instructions or canceling and re-scheduling if needed. \Returns true on success, false otherwise.
