Making C++ and the STL Work in the Linux / Windows Kernels
summary
Bootstraps a C++11/14 runtime inside Linux and Windows kernels by using a cross‑compiler, a custom ELF loader, manual relocations, and handcrafted support for global constructors/destructors, then implements a kernel-safe unwinder that consumes eh_frame data so full exceptions and RTTI (dynamic_cast) work. Results: a working open‑source Bareflank hypervisor (type‑1 and late‑launch type‑2) with CI, unit tests, Coveralls and clang‑tidy; debugging steps include fixing the red zone and resolving weak‑symbol issues in libc++/libc++abi.
