English(EN) Linux prepares to axe legacy x32 hybrid mode — hybrid 32-bit/64-bit mode faces complete removal by 2027 due to low adoption

Linux 内核将于 2027 年放弃 x32 混合模式

Linux 开发者提议在 2027 年前从 Linux 内核中移除 x32 ABI,这是一种混合 32 位/64 位模式。该模式于 2012 年推出,旨在通过使用 32 位指针同时保留 64 位寄存器来优化 64 位应用程序的内存使用。然而,由于增加了复杂性、每个进程 4GB 的内存限制以及与标准 64 位操作相比性能提升不足,该模式的采用率有限。该模式也仅限于 Linux,从未被移植到其他主要操作系统。 AI
