This patch adds -mshared option to x86 ELF assembler. By default, assembler will optimize out non-PLT relocations against defined non-weak global branch targets with default visibility. The -mshared option tells the assembler to generate code which may go into a shared library where all non-weak global branch targets with default visibility can be preempted. The resulting code is slightly bigger. This option only affects the handling of branch instructions. This Linux kernel patch is needed to create a working x86 Linux kernel if it hasn't been applied: diff --git a/arch/x86/kernel/head_64.S b/arch/x86/kernel/head_64.S index ae6588b..b91a00c 100644 --- a/arch/x86/kernel/head_64.S +++ b/arch/x86/kernel/head_64.S @@ -339,8 +339,8 @@ early_idt_handlers: i = i + 1 .endr -/* This is global to keep gas from relaxing the jumps */ -ENTRY(early_idt_handler) +/* This is weak to keep gas from relaxing the jumps */ +WEAK(early_idt_handler) cld cmpl $2,(%rsp) # X86_TRAP_NMI -- gas/ * config/tc-i386.c (shared): New.
