Generates execute-only code by adding the

To keep code and data in separate sections, the compiler disables literal pools and branch tables. That is, specifying
--execute_only implicitly specifies the following compiler options:
Execute-only code must be Thumb code.
Execute-only code is only supported on the following processors:
If your application calls library functions, the library objects included in the image are not execute-only compliant. You must ensure these objects are not assigned to an execute-only memory region.
