- linked in (crtbegin.o/end.o) are tailored to provide this service
- automatically, a-la C++ constructor fashion, triggered by the VxWorks
- loader thanks to a special variable declaration in crtbegin.o (_ctors).
-
- Automatic de-registration is handled symmetrically, a-la C++ destructor
- fashion (with a _dtors variable also in crtbegin.o) triggered by the
- dynamic unloader.
-
- Note that since the tables shall be registered against a common
- data structure, libgcc should be one of the modules (vs being partially
- linked against all the others at build time) and shall be loaded first.
-
- For applications linked with the kernel, the scheme above would lead to
- duplicated symbols because the VxWorks kernel build "munches" by default,
- so we link against crtbeginT.o instead of crtbegin.o, which doesn't
- include the special variables. We know which set of crt objects is used
- thanks to a boolean indicator present in both sets (__module_has_ctors),
- and directly call the appropriate function here in the not-automatic
- case. We'll never unload that, so there is no de-registration to worry
- about.
-
- For whole applications loaded as a single module, we may use one scheme
- or the other, except for the mixed Ada/C++ case in which the first scheme
- would fail for the same reason as in the linked-with-kernel situation.
-
- The crt set selection is controlled by command line options via GCC's
- STARTFILE_SPEC in rs6000/vxworks.h. This is tightly synchronized with a
- number of other GCC configuration and crtstuff changes, and we need to
- ensure that those changes are there to activate this circuitry. */

- to the ctors symbols here would just remain unsatisfied.
-
- We have no way to avoid those references in the right conditions in this
- C module, because we have nothing like a IN_ZCX_RTS macro. This aspect
