These options control how objects are linked:
‑‑match crossmangledInstructs the linker to match the following combinations together:
a reference to an unmangled symbol with the mangled definition
a reference to a mangled symbol with the unmangled definition.
Libraries and matching operate as follows:
If the library members define a mangled definition, and there is an unresolved unmangled reference, the member is loaded to satisfy it.
If the library members define an unmangled definition, and there is an unresolved mangled reference, the member is loaded to satisfy it.
Note
This option has no effect if used with partial linking. The partial object contains all the unresolved references to unmangled symbols, even if the mangled definition exists. Matching is done only in the final link step.
‑‑strictInstructs the linker to report conditions that might result in failure as errors, rather than warnings. An example of such a condition is taking the address of an interworking function from a non-interworking function.
‑‑[no_]strict_relocations‑‑strict_relocationinstructs the linker to report instances of obsolete and deprecated relocations.Relocation errors and warnings are most likely to occur if you are linking object files built with previous versions of the ARM tools.
This option enables you to ensure ABI compliance of objects. It is off by default, and deprecated and obsolete relocations are handled silently by the linker, where possible.
‑‑unresolvedsymbolMatches each reference to an undefined symbol to the global definition of
