machine code的示例

• The composition of these functors will give a method of transforming a high-level type-system description into a machine code analyzer.

• It has the flavour of machine code, with combinators playing the role of program addresses and parameterization the role of register transfer.

• Consequently, the final machine code will also be more efficient.

• More generally, we could imagine generating some form of abstract machine code as programs are parsed.

• It also leaves several options open for compilation to target machine code.

• The verifier is able to prove memory safety of x86 machine code programs compiled from code that uses algebraic datatypes.

• The display representation would then be one or more bitmaps augmented by custom-generated machine code.

• The abstract machine code is optimized in compile-time by referring to the result of dataflow analysis with abstract interpretation.

• Next, we describe a particular completed application of that library, a memory safety verifier for machine code programs that use algebraic datatypes.

• The switches are not (usually) conceived of as such but as sequences of ones and zeros, as machine code, or even as high-level programming code.

• In particular, we have developed a framework for coding certified program verifiers for x86 machine code programs.

• Since no compiled machine code is involved, unloading such abstract machines is easier than unloading an abstract machine based on compiled code.

• We cannot improve on this without direct access to machine code.

• The generated (high-level) code corresponds closely to machine code, and should compile into a light-weight subroutine.

• Finally, the abstract machine code is translated to binary code for a specific target.
