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/src/boot/entry64.s | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/x86_64/src/boot/entry64.s') diff --git a/arch/x86_64/src/boot/entry64.s b/arch/x86_64/src/boot/entry64.s index f575c50..110ced8 100644 --- a/arch/x86_64/src/boot/entry64.s +++ b/arch/x86_64/src/boot/entry64.s @@ -12,8 +12,8 @@ _entry64: xor %rax, %rax - call _init - + call invoke_global_constructors + call main 1: -- cgit v1.2.3
