Hello World!
Published in Syed R. Rizvi, Microcontroller Programming, 2016
The linker can now take the object code generated by the assembler and create the final absolute code that will be executed on the target system. The emulation phase will take the absolute code and load it into the development system RAM. From here, the program may be debugged using breakpoints or single-stepping. A breakpoint in software development is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also referred to as a pause. More generally, a breakpoint is a means of acquiring knowledge about a program during its execution. Single-stepping is used when precise control over instruction execution is required. As each instruction is executed, control is passed back to the debugger, which disassembles the next instruction to be executed. Team Discussion: Map each field from Table 7.4 to the HELLO.S19 file given in Figure 7.4. You may refer to the HELLO.LST file given in Figure 7.5.Helpful Hint: For error messages, look at the assembler output listing file generated during assembly.Common Practice: Many times the free assembler is an old DOS tool that does not recognize long file names. For that reason, most programmers do not use long file names (> 8 characters).

debugger a computer program used to debug. Debuggers are designed to help in debugging another program by allowing the programmer to step through the program, examine data, and check conditions. There are two basic types of debuggers: machine-level and source-level. Machine-level debuggers display the actual machine instructions (disassembled into Assembly language) and allow the programmer to look at registers and memory locations. Source-level debuggers let the programmer look at the original source code (C for example), examine variables and data structures by name, and so on.

Debugging system design. Debugging is a basic term in software development and it is defined as ‘the attempt to pinpoint and fix the source of an error’ [20]. In practice, debugging is a complex process influenced byusers' experience levels and the tools they have at their disposal. Lawrance et al. [22] found that software developers usually find a clue in the program first for debugging tasks. Ikeda and Szafir [21] reported that the provided visualization tool via 2D and 3D displays could improve the expert users' debugging capabilities. Eclipse IDE, a well-known tool for the Java language, provides features for debugging software such as showing logs, variables, and breakpoints [5]. Murphy et al. [6], Beller et al. [7], and Perscheid et al. [9] reported that the breakpoint feature is one of the most frequently used features in software development practice. In our system, we provide four components of debugging tools including (i) setting breakpoints, (ii) logging node status, (iii) monitoring node execution, and (iv) variables to allow non-expert users to figure out the problems.
A novel approach for mutant diversity-based fault localization: DAM-FL

Software testing and debugging are important and time-consuming activities in software development because even after development if the software is erroneous then it will not do the intended work. Boehm [1] suggested that between 25% and 50% of the total cost and time of system development may be occupied by debugging and testing. First, faults are detected while testing then debugging is done. Debugging consists of fault localization, i.e. locating the faulty parts of software with the help of given test execution failures and fault removal, i.e. correcting it to resolve the fault. Fault localization approaches provide data regarding the origin of failures or program's locations which are suspicious of causing failures. Localizing faults is one of the costlier parts of debugging, and thus more research effort is needed for optimizing fault localization. Thus, the quality of test cases should be such that the fault localization efficacy of the test suites is not conceded.
