Compiling for debug

3.1.3

SW4STM32

In project Properties->Settings->Tool Settings->MCU GCC Compiler->Optimization

Figure 12. SW4STM32 Optimization Level setting

gcc also provides the -Og option:

-Og enables optimizations that do not interfere with debugging. It offers a reasonable level

of optimization while maintaining fast compilation and a good debugging experience.

3.2

Debugging information

Debugging information is generated by the compiler together with the machine code. It is a

representation of the relationship between the executable program and the original source

code. This information is encoded into a pre-defined format and stored alongside the

machine code.

Debugging information is mandatory to set breakpoint or get the content of a variable.

This chapter presents the location of the Debugging Information related option in IAR

™,

Keil®, and SW4STM32.
