Problems solved by technology

[0004] Implementing a debugger for interpreted code is usually less complex than implementing a debugger for native code
However, the response time of a debugger for native code is usually faster than for interpreted code

Embodiment Construction

[0017] overview

[0018] You can debug a program by compiling it to native code and debugging the native code. At defined points in the program, debugging can transition from native mode to interpreted mode, and debugging can continue on the interpreted code. Debugging operations involving execution control: pausing execution, resuming execution, stepping into, stepping out, or stepping over code fragments, etc., can occur in interpreted mode. Debug operations involving inspection and modification of variables can occur in native mode. Dual-mode debuggers combine the speed of native-mode debugging with the simplicity of interpreted-mode debugging.

Abstract

The dual-mode debugger can debug native code or interpreted code. Transitions between modes can be triggered by defined exit conditions. A program can be debugged by attaching a debugger and compiling the program to native code under the debugger. At defined points in the program, debugging can transition from native mode to interpreted mode. Debugging of native code can be stopped, the current state can be captured, and the interpreter can be instantiated. An interpreter stack can be created and filled with the captured current state. Debugging operations that involve execution control: pausing execution, resuming execution, stepping in, out, or stepping through code fragments, etc., can happen in interpreted mode, which is usually easier to implement. Debug operations involving inspection and modification of variables can occur in native mode.

Description

technical field [0001] The present invention relates to computer technology, and more particularly, to methods and systems for debugging native code. Background technique [0002] A compiler can produce executable code by compiling source code into code that can be executed by a particular processor. This type of processor-specific code is called "native machine code," or machine instructions that can be executed by a particular type of processor, but not by any type of processor. Another type of compiler takes source code and produces intermediate code or virtual machine byte code that is not processor specific. The intermediate code is typically received by an intermediate language compiler (eg, a just-in-time (JIT) compiler) and compiled into native machine code just before program execution. Intermediate code is not platform-specific. [0003] An interpreter reads source or intermediate code and executes the code statement by statement without converting the code to n...
