Recommended compiler settings:
- "-g": Debug symbols needed for best analysis results.
+ "-g": Debug information, such as line numbers, needed for best analysis results.
"-fno-inline": Speed improvement when processing the image files and most accurate analysis results.
"-fno-omit-frame-pointer": ARM EABI frame pointers (Code Sourcery cross compiler) allow recording of the call stack with each sample taken when in ARM state (i.e. not -mthumb).
"-marm": This option is required if your compiler is configured with --with-mode=thumb, otherwise call stack unwinding will not work.
