From 6716dbbdefa9867ba98dea91d89b14168043a48c Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Mon, 24 Jun 2013 21:22:06 +0530 Subject: ARC: dw2 unwind: switch to .eh_frame based unwinding So finally after almost 8 years of dealing with .debug_frame, we are finally switching to .eh_frame. The reason being stripped kernel binaries had non-functional unwinder as .debug_frame was gone. Also, in general .eh_frame seems more common way of doing unwinding. This also folds a revert of f52e126cc747 ("ARC: unwind: ensure that .debug_frame is generated (vs. .eh_frame)") to ensure that we start getting .eh_frame Reported-by: Daniel Mentz Signed-off-by: Vineet Gupta --- arch/arc/kernel/entry.S | 12 ------------ 1 file changed, 12 deletions(-) (limited to 'arch/arc/kernel/entry.S') diff --git a/arch/arc/kernel/entry.S b/arch/arc/kernel/entry.S index 2efb0625331d..741712d4d6ff 100644 --- a/arch/arc/kernel/entry.S +++ b/arch/arc/kernel/entry.S @@ -61,18 +61,6 @@ ENTRY(ret_from_fork) b ret_from_exception END(ret_from_fork) -#ifdef CONFIG_ARC_DW2_UNWIND -; Workaround for bug 94179 (STAR ): -; Despite -fasynchronous-unwind-tables, linker is not making dwarf2 unwinder -; section (.debug_frame) as loadable.
