From 0d6378a9e3e589217fda7be9ae273aee14540fe0 Mon Sep 17 00:00:00 2001 From: jakub Date: Sat, 15 Dec 2001 11:49:18 +0000 Subject: * 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@48039 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/config/linux.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'gcc/config/linux.h') diff --git a/gcc/config/linux.h b/gcc/config/linux.h index 4743ffedb28..6e60c008d85 100644 --- a/gcc/config/linux.h +++ b/gcc/config/linux.h @@ -50,12 +50,22 @@ Boston, MA 02111-1307, USA. */ object constructed before entering `main'. */ #undef STARTFILE_SPEC +#ifdef USE_GNULIBC_1 #define STARTFILE_SPEC \ "%{!shared: \ %{pg:gcrt1.o%s} %{!pg:%{p:gcrt1.o%s} \ %{!p:%{profile:gcrt1.o%s} \ %{!profile:crt1.o%s}}}} \ crti.o%s %{!shared:crtbegin.o%s} %{shared:crtbeginS.o%s}" +#else +#define STARTFILE_SPEC \ + "%{!shared: \ + %{pg:gcrt1.o%s} %{!pg:%{p:gcrt1.o%s} \ + %{!p:%{profile:gcrt1.o%s} \ + %{!profile:crt1.o%s}}}} \ + crti.o%s %{static:crtbeginT.o%s}\ + %{!static:%{!shared:crtbegin.o%s} %{shared:crtbeginS.o%s}}" +#endif /* Provide a ENDFILE_SPEC appropriate for GNU/Linux.
