The ARM linker conforms to the Base Platform ABI for the ARM Architecture (BPABI) and supports the GNU-extended symbol versioning model.
To add a symbol version to an existing symbol, you must define a version symbol at the same address. A version symbol is of the form:
ifname
@ver
ver
is a non default version ofname
ifname
@@ver
ver
is the default version ofname
.
The version symbols must be enclosed in vertical bars.
For example, to define a default version:
|my_versioned_symbol@@ver2| ; Default version my_asm_function PROC ... BX lr ENDP
To define a non default version:
|my_versioned_symbol@ver1| ; Non default version my_old_asm_function PROC ... BX lr ENDP
