Avoid References to Compiler-Specific Libraries
Advantages of this method:
The compiler will not assume the presence of compiler-specific libraries. It will generate only calls that appear in the source code.
Disadvantages of this method:
This method may sacrifice performance if the library codes were in hotspots. Also, because we cannot assume any libraries, some compiler optimizations will be suppressed.
- This option implies option-fno-builtin; you can override that default by explicitly specifying option-fbuiltin.
- Depending on code characteristics, this option can sometimes increase binary size.
