    Abstract
    Producing compilers that generate good object code is difficult. The early phases of the compiler, syntactical and lexical analysis, have been automated. The latter phases, code generation and optimization, are more difficult because of the wide range of machine architectures. This dissertation describes a technique for the rapid implementation of production-quality compilers though the use of a machine-independent retargetable peephole optimizer, PO. PO is retargeted by providing a description of the new machine. PO simplifies many of the tasks associated with developing compilers. It simplifies code generation by eliminating most of the case-analysis typically necessary to produce good code. It simplifies the optimization phase by collecting several disparate optimizations and generalizing them as peephole optimizations. PO also demonstrates the traditional optimizations, such as register allocation, common subexpression elimination, and removal of unreachable code, may be done more thoroughly and completely when information about the target machine is available.

    Export search results

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
