	gcc            : ChangeLog gcc.c config.gcc configure config.in 
	                 configure.in crtstuff.c unwind-dw2-fde.c 
	                 Makefile.in mklibgcc.in 
	gcc/config/i386: gnu.h 
	gcc/config/ia64: fde-glibc.c linux.h 
	gcc/config/sparc: linux.h t-linux64 linux64.h 
	gcc/config     : t-linux linux.h t-linux-gnulibc1 

Log message:
	* configure.in: Check for ld.
	(HAVE_LD_EH_FRAME_HDR): Define if ld supports --eh-frame-hdr option.
	* configure, config.in: Rebuilt.
	* config.gcc: Add crtbeginT.o to extra_parts where needed.
	* config/t-linux (LIB2ADDEH, LIB2ADDEHDEP): Use unwind-dw2-fde-glibc
	frame unwinding on Linux.
	* config/t-linux-gnulibc1 (LIB2ADDEH, LIB2ADDEHDEP): Use unwind-dw2-fde
	frame unwinding.
	* config/linux.h (STARTFILE_SPEC): Use crtbeginT.o for -static.
	(LINK_EH_SPEC): Define.
	* config/i386/gnu.h (STARTFILE_SPEC): Use crtbeginT.o for -static.
	* config/ia64/linux.h (STARTFILE_SPEC, LINK_EH_SPEC): Define.
	* config/ia64/fde-glibc.c (_Unwind_IteratePhdrCallback): Don't
	iterate further if pc falls into current library, but fde was not
	found.
	* config/sparc/linux.h (STARTFILE_SPEC): Use crtbeginT.o for -static
	if using glibc.
	(LINK_EH_SPEC): Define.
	* config/sparc/linux64.h (STARTFILE_SPEC32, STARTFILE_SPEC64):
	Use crtbeginT.o for -static.
	(LINK_EH_SPEC): Define.
	* config/sparc/t-linux64 (EXTRA_MULTILIB_PARTS): Add crtbeginT.o.
	* Makefile.in (crtbeginT.o): Add rule.
	* gcc.c (init_gcc_specs): For -static-libgcc, use -lgcc -lgcc_eh.
	If neither -static-libgcc nor -shared-libgcc is passed and -shared,
	use -lgcc if LINK_EH_SPEC is defined and -lgcc_s -lgcc if not.
	If none of the above switches are passed, use -lgcc -lgcc_eh.
	(init_spec): If LINK_EH_SPEC is defined, prepend it to link_spec.
	* mklibgcc.in: Don't include LIB2ADDEH objects into libgcc.a if
	creating libgcc_s.so, put them into separate libgcc_eh.a instead.
	* unwind-dw2-fde.c: Don't include any headers if this file
	is included from other .c file.
	* unwind-dw2-fde-glibc.c: New file.
	* crtstuff.c (USE_PT_GNU_EH_FRAME, USE_EH_FRAME_REGISTRY): Define.
	Use it instead of EH_FRAME_SECTION_NAME where appropriate.
