I am creating a modular kernel, and for that I have a ModuleLoader. I have read that for freestanding compilation the build system (ld) does not creating any DT_INIT dynamic entry in the table (dynamic section). Before creating threads for each module's KModuleMain function, I need a mechanism to call their internal initialization function especially to call the global object constructors. Does anyone know how to set a DT_INIT function in the linker-script for ld & how to call all global object constructors in the shared library (kernel modules are implemented as dynamic shared libraries in the CircuitKernel)?

Just found out the answer on my own while developing the C++ runtime features for my kernel . One linking the infamous crti.o and crtn.o object files, the DT_INIT and DT_FINI tags are automatically emitted by the compiler/linker toolchain. I don't think there is any other way to do so, right?
