9917 | To improve the debug information accuracy, you can reduce the | ||
9918 | level of optimization used by the compiler. | ||
9919 | For example, when adding the following line to your | ||
9920 | <filename>local.conf</filename> file, you will reduce | ||
9921 | optimization from | ||
9922 | <ulink url='&YOCTO_DOCS_REF_URL;#var-FULL_OPTIMIZATION'><filename>FULL_OPTIMIZATION</filename></ulink> | ||
9923 | of "-O2" to | ||

9929 | Consider that this will reduce the application's performance | ||
