| 2025-07-24 | x86_64: implement robust C++ global initialization | Felix Morgner | 4 | -24/+26 | |
| Implement a comprehensive mechanism to ensure correct C++ runtime initialization before the kernel main function is called. This replaces the previous, incomplete reliance on an `_init` function. The new design robustly handles both legacy `.ctors` and modern `.init_array` initialization schemes used by the GNU toolchain. A single C++ function, `invoke_global_constructors`, now iterates through both arrays of function pointers to ensure all types of global initializers are executed. | |||||

| 2025-07-18 | x86_64: don't lose multi boot information pointer | Felix Morgner | 1 | -2/+2 | |
| Since the transition to a PIE, more registers are required to perform the relative lookups of data references. As part of that change, a subtle mistake was introduced in _start, overwriting the multiboot information pointer that gets handed to kernel by the boot loader in %ebx. | |||||
