Abstract: A pipeline development environment includes a toolset that includes a visual design editor. The editor comprises a display interface having a palette of known Annotators that may be selected by a developer. The pipeline development environment also includes or has associated therewith a data repository. The data repository stores datasets. A particular dataset is associated with an Annotator and comprises dependency data generated from execution of a pipeline (or some portion thereof). The repository typically stores datasets from many pipeline runs, including runs of other pipelines, multiple runs of a given pipeline with different inputs, etc. Using the editor, a developer creates a visual representation of the pipeline. As Annotators are added into the pipeline, system tooling dynamically generates the descriptor files and other configuration parameters (for the new pipeline), preferably based on the dependency data associated with the individual Annotators and retrieved from the repository.

A non-contiguous specifier specifies a resource of an instruction, such as a register, using multiple fields of the instruction. For example, multiple fields of the instruction (e.g., two fields) include bits that together designate a particular register to be used by the instruction. Non-contiguous specifiers of instructions defined in one computer system architecture are transformed to contiguous specifiers usable by instructions defined in another computer system architecture. The instructions defined in the another computer system architecture emulate the instructions defined for the one computer system architecture.
