ARM Compiler armcc User Guide : 8.106 --inline, --no

8.106 --inline, --no_inline

Enables and disables the inlining of functions. Disabling the inlining of functions can help to improve the debug illusion.

When the option --inline is selected, the compiler considers inlining each function. Compiling your code with --inline does not guarantee that all functions are inlined, as the compiler uses a complex decision tree to decide whether to inline a particular function.

When the option --no_inline is selected, the compiler does not attempt to inline functions, other than functions qualified with __forceinline.
