[PATCH] x86_64: More CFI fixes for 32bit entry code

[GitHub/mt8127/android_kernel_alcatel_ttab.git] / include / asm-x86_64 / dwarf2.h

#ifndef _DWARF2_H
#define _DWARF2_H 1

#include <linux/config.h>

#ifndef __ASSEMBLY__
#warning "asm/dwarf2.h should be only included in pure assembly files"
#endif

/* 
   Macros for dwarf2 CFI unwind table entries.
   See "as.info" for details on these pseudo ops. Unfortunately 
   they are only supported in very new binutils, so define them 
   away for older version.
