Syntax
‑‑no_alt_link_reg_opt
Description
Use this option to disable an optimization that can change the link register used for static functions. Using non-standard registers as link registers allows for smaller and faster calls, but can also make it impossible for some trace interfaces to analyze the program flow.
Caution
To set this option, use Project>Options>C/C++ Compiler>Extra Options.
