Virtual Function Elimination (VFE) is a technique that enables the linker to identify more unused sections.
Use this option to specify how VFE, and Runtime Type Information (RTTI) objects, are eliminated.
--vfemode=mode
where mode
onUse the command-line option
--vfemode=onto make the linker VFE aware.In this mode the linker chooses
forceoroffmode based on the content of object files:Where every object file contains VFE information or does not refer to a symbol with a mangled C++ name, the linker assumes
forcemode and continues with the elimination.If any object file is missing VFE information and refers to a symbol with a mangled C++ name, for example, where code has been compiled with a previous release of the ARM tools, the linker assumes
offmode, and VFE is disabled silently. Choosingoffmode to disable VFE in this situation ensures that the linker does not remove a virtual function that is used by an object with no VFE information.
offUse the command-line option
--vfemode=offto make armlink ignore any extra information supplied by the compiler. In this mode, the final image is the same as that produced by compiling and linking without VFE awareness.forceUse the command-line option
--vfemode=forceto make the linker VFE aware and force the VFE algorithm to be applied. If some of the object files do not contain VFE information, for example, where they have been compiled with a previous release of the ARM tools, the linker continues with the elimination but displays a warning to alert you to possible errors.force_no_rttiUse the command-line option
--vfemode=force_no_rttito make the linker VFE aware and force the removal of all RTTI objects. In this mode all virtual functions are retained.
