From f62b05c93c6c539d899d2656c0638d404a036f1a Mon Sep 17 00:00:00 2001 From: Felix Morgner Date: Thu, 24 Jul 2025 12:28:23 +0000 Subject: x86_64: implement robust C++ global initialization 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. --- arch/x86_64/CMakeLists.txt | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'arch/x86_64/CMakeLists.txt') diff --git a/arch/x86_64/CMakeLists.txt b/arch/x86_64/CMakeLists.txt index 6bb9e53..58daa3b 100644 --- a/arch/x86_64/CMakeLists.txt +++ b/arch/x86_64/CMakeLists.txt @@ -35,9 +35,8 @@ target_sources("arch-x86_64" PRIVATE target_sources("arch-x86_64" PRIVATE "src/boot/boot32.S" - "src/boot/crti.s" - "src/boot/crtn.s" "src/boot/entry64.s" + "src/boot/initialize_runtime.cpp" "src/boot/multiboot.s" ) -- cgit v1.2.3
