12.5 Option of C Compiler/Assembler/Linker 

We do not evaluate other settings, so we can not recommend to append other options. 
 

12.5.1 When Using NCxx 

When -O, -OR or -OS option is specified at compilation, the source line information may not be 
generated normally due to optimization, causing step execution to be operated abnormally. 
To avoid this problem, specify -ONBSD (or -Ono_Break_source_debug) option together with -O, -OR or 
OS option.

the name of the function will be not available. Please do not use the option to make the name 
available.
