Port libvtv to Solaris
libstdc++-v3:
* acinclude.m4 (GLIBCXX_ENABLE_VTABLE_VERIFY) <solaris2*>: Use
-Wl,-R in VTV_CXXLINKFLAGS.
* configure: Regenerate.
* testsuite/18_support/bad_exception/23591_thread-1.c: Use
-fvtable-verify=none on Solaris 12+.
libgcc:
* Makefile.in (VTV_CFLAGS): New variable.
(vtv_start$(objext), vtv_end$(objext), vtv_end$(objext))
(vtv_start_preinit$(objext), vtv_end_preinit$(objext)): Use it.
* config.host (*-*-solaris2*): Add t-crtstuff-pic to tmake_file.
Add vtv_start.o, vtv_end.o, vtv_start_preinit.o, vtv_end_preinit.o
to extra_parts if $enable_vtable_verify = yes.
libvtv:
* configure.tgt (*-*-solaris2.[1-9]*): Declare supported.
* configure.ac: Call AC_USE_SYSTEM_EXTENSIONS.
<*-*-solaris2*>: Check for init priority support.
Check for getexecname, __fortify_fail, _obstack_begin.
(VTV_NO_OBSTACK): New conditional.
* configure: Regenerate.
* Makefile.am [VTV_NO_OBSTACK] (obstack.c): Use new condition.
Create empty config.h
* Makefile.in: Regenerate.
* vtv_rts.cc [HAVE_GETEXECNAME] (program_invocation_name): New
variable.
(read_section_offset_and_length) [HAVE_GETEXECNAME]: Set it.
(dl_iterate_phdr_callback) [HAVE_GETEXECNAME]: Set it.
(__fortify_fail): Wrap in HAVE___FORTIFY_FAIL
[!HAVE___FORTIFY_FAIL]: Provide non-Cygwin implementation.
(read_section_offset_and_length): Assert sh_size >= VTV_PAGE_SIZE.
(iterate_modules): Fix typo.
Use VTV_PAGE_SIZE.
(dl_iterate_phdr_callback): Fix typo.
Use VTV_PAGE_SIZE.
(__VLTChangePermission): Fix typos.
include:
* vtv-change-permission.h (VTV_PAGE_SIZE) [__sun__ && __svr4__ &&
__sparc__]: Define.
gcc:
* config/sol2.h (SUPPORTS_INIT_PRIORITY): Move up.
(STARTFILE_VTV_SPEC, ENDFILE_VTV_SPEC): Define.
(STARTFILE_SPEC): Use %(startfile_vtv).
(ENDFILE_SPEC): Use %(endfile_vtv).
(SUBTARGET_EXTRA_SPECS): Handle STARTFILE_VTV_SPEC,
ENDFILE_VTV_SPEC.
* gcc.c (LINK_COMMAND_SPEC): Move VTABLE_VERIFICATION_SPEC after %{L*}.
