CompilerRuntimeErrorAction

New in 14.1[Experimental]

CompilerRuntimeErrorAction

is an option for FunctionCompile that determines what should happen when an unrecoverable error takes place while computing with low-level code.

Details

  • With the default setting of Automatic, the computation will be rerun in the Wolfram Engine if it avoids compiler-specific code.
  • Possible settings for CompilerRuntimeErrorAction are:
  • Automaticrerun the computation in the Wolfram Engine if it avoids compiler-specific code
    "Evaluate"always rerun the computation in the Wolfram Engine
    Nonereturn a failure object that represents the error
    funapply fun to the failure object and return the result

Examples

Basic Examples  (3)Summary of the most common use cases

Generate compiled code with the default CompilerRuntimeErrorAction:

There is an error due to integer overflow and the computation is rerun by the evaluator:

Generate compiled code with CompilerRuntimeErrorAction set to None:

Now the error is not rerun in the Wolfram Engine; instead a Failure is returned:

If the function contains code specific for the compiler, the default setting of CompilerRuntimeErrorAction does not run in the evaluator:

Generate compiled code with CompilerRuntimeErrorAction set to None:

Now the error is not rerun in the Wolfram Engine:

Setting CompilerRuntimeErrorAction to "Evaluate" indicates that if any error occurs, the computation will be rerun in the evaluator:

Now the error is rerun in the Wolfram Engine:

CompilerRuntimeErrorAction can take a function to apply to the failure object:

The failure is returned wrapped in a frame:
