3.5.10 How Do I Know What Code the Compiler Is Producing?

The assembly list file may be set up, using assembler listing file options, to contain a great deal of information about the code, such as the assembly output for almost the entire program, including library routines linked in to your program, section information, symbol listings, and more.

The list file may be produced as follows:

• On the command line, create a basic list file using the option:
-Wa, -a=projectname.lst.
• For MPLAB X IDE, right click on your project and select “Properties.” In the Project Properties window, click on “xc32-as” under “Categories.” From “Option categories,” select “Listing file options” and ensure “List to file” is checked.

By default, the assembly list file will have a .lst extension.

For information on the list file, see the “MPLAB^® XC32 Assembler, Linker and Utilities User’s Guide” (DS50002186).
