configure.in: Check for ld.
* 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.
