Hello

You can let CodeWarrior disassemble the generated code.

This is done in the following way:

- Open your project in CodeWarrior

- Open the Target settings dialog (press ALT + F7)

- Switch to the "EPPC Disassembler" panel

- Check "Show Source Code" check box.

- Click OK to close the dialog.

- Open the C source file, where you have the instruction in an edit window

- Click with the right mouse button in the edit window

- Select Disassemble. A new window is opened showing disassembly listing.

Scroll down until you see source code for your function and check the code

generated by the compiler here.
