don't allow a defn resolving to that address.
* elf/link.h: Update prototype and comment.
* elf/dl-runtime.c (fixup): Define local `resolve' function and pass
it to elf_machine_relplt.
* elf/dl-reloc.c (_dl_relocate_object: resolve): Take new arg
RELOC_ADDR and pass it through to _dl_lookup_symbol.
* elf/do-rel.h (elf_dynamic_do_rel): Pass RESOLVE to elf_machine_rel
instead of calling it ourselves and passing its results.
(elf_dynamic_do_rel): RESOLVE fn takes new arg RELOC_ADDR.
* elf/rtld.c (dl_main): Pass 0 for RELOC_ADDR to _dl_lookup_symbol.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Remove SYM_LOADADDR
arg. Add RESOLVE function ptr arg. Call *RESOLVE as necessary.
* sysdeps/m68k/dl-machine.h (elf_machine_rela): Likewise.
* sysdeps/stub/dl-machine.h: Likewise.
* csu/initfini.c (_fini): Add extern decl for i_am_not_a_leaf.
* elf/dlfcn.h (dl_open_mode): Enumerated type removed.
(RTLD_LAZY, RTLD_NOW): Define these as macros instead.
(RTLD_GLOBAL): New macro.
(dlopen): Take arg of type int instead of dl_open_mode.
* elf/dlopen.c: Likewise.
* math/math.h (_Mldbl): New macro, either produces L suffix or not.

* sysdeps/unix/sysv/linux/syscalls.list: Add bdflush,
create_module, delete_module, get_kernel_syms, init_module,
klogctl.
* sysdeps/unix/sysv/linux/sys/param.h (MAXSYMLINKS): Define as 5
instead of SYMLOOP_MAX, which is nowhere to be found.
* sysdeps/unix/sysv/linux/sys/msq_buf.h,
sysdeps/unix/sysv/linux/sys/sem_buf.h,
sysdeps/unix/sysv/linux/sys/shm_buf.h [__USE_MISC]: Add more

(ret): Delete macro. It was a dangerous macro and unnecessary
since the Alpha assemblers recognizes "ret" as a macro themselves.
* sysdeps/gnu/utmpbits.h (struct utmp): Move ut_tv behind
ut_session to guarantee long alignment. This is important for
Linux/Alpha since ut_tv.tv_sec is 32 bits and time_t is 64 bits.
This will all get cleaned up as programs start to use ut_tv
instead ut_time.

.end directive.
* csu/initfini.c (_fini): Tell gcc that _fini is not a leaf
function by having it contain a dummy function call.
* configure.in (config_machine): Don't make ELF the default for
Linux/Alpha just yet (use --with-elf instead).
(.init/.fini check): Generate .text to ensure function start and
end are in same section.
* sysdeps/unix/bsd/osf/alpha/brk.S,
sysdeps/unix/sysv/linux/alpha/brk.S (__curbrk): Store the entire
break value, not just the low 32 bits to accomodate large
memories.
Tue May 28 10:46:04 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/unix/sysv/linux/alpha/brk.S: Rather than attempt to
dynamically resolve _end for initializing __curbrk, support the
brk(0) query idiom.

sys/klog.h, and sys/kdaemon.h.
* sysdeps/unix/sysv/linux/sys/io.h: New file.
* sysdeps/unix/sysv/linux/sys/klog.h: Ditto.
* sysdeps/unix/sysv/linux/sys/kdaemon.h: Ditto.
* sysdeps/unix/alpha/sysdep.h (ret): Remove macro. It is
dangerous and unnecessary since both OSF/1 as and gas define "ret"
as a pseudo-instruction.
Sat Jun 1 17:18:21 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* time/tzset.c (__tzset): Clear tz_rules name pointers after freeing
them. Bug found by David Mosberger-Tang.
* sysdeps/posix/tempname.c (__stdio_gen_tempname): Use __ptr_t instead
of PTR.
* extra-lib.mk (extra-objs): Use patsubst intead of $(A:=B) syntax
to work around Make bug when A contains var ref.

struct member name: sc_eip -> eip.
* csu/initfini.c (_init): Remove bogus volatile declarations and

(start-installed-rule, start-installed-name-rule): New variables;
specify crt1.o, created by our own rule.
($(objpfx)crt1.o): New rule.

AC_CACHE_VAL uses to use new AC_CACHE_CHECK macro instead;
prettify some messages.
[$elf!=yes] (libc_cv_have_initfini): New test for `.init' and `.fini'
sections.

add crti_s, crtn_s.
(install-lib, extra-objs, generated-, omit-deps): Use that.
(initfini): New canned sequence, broken out of crt[in].s rule.
(crt[in].s rule): Use it.

without a leading zero.
