* sysdeps/unix/alpha/sysdep.h: Move error-handling code in PSEUDO
to PSEUDO_END to improve branch-prediction. Include .frame
directive to make syscalls debugabble.
(PSEUDO_END): New macro.
* sysdeps/unix/alpha/sysdep.h, sysdeps/alpha/bb_init_func.S,
sysdeps/unix/sysv/linux/alpha/brk.S: Use ldiq instead of ldi since
latter is illegal under DEC Unix.
* sysdeps/unix/alpha/sysdep.S: Renamed from
sysdeps/unix/sysv/linux/alpha/sysdep.S. This file works for OSF/1
as well.
* sysdeps/unix/bsd/osf/alpha/sysdep.S: Remove (note that the
EWOULDBLOCK -> EAGAIN mapping was unnecessary since
EWOULDBLOCK==EAGAIN under DEC Unix and Linux/Alpha).
* math/Makefile (headers): Add fpu_control.h.
(aux): New variable, list fpu_control and setfpucw.
* sysdeps/generic/fpu_control.c: New file.
* sysdeps/stub/fpu_control.h: New file.
* sysdeps/unix/sysv/linux/m68k/fpu_control.h: Moved to ...
* sysdeps/m68k/fpu_control.h: here.
* sysdeps/unix/sysv/linux/i386/fpu_control.h: Moved to ...
* sysdeps/i386/fpu_control.h: here.
* sysdeps/unix/sysv/linux/alpha/fpu_control.h: Moved to ...

* sysdeps/unix/sysv/linux/alpha/Makefile (sysdep_routines): Remove
setfpucw, fpu_control.
* sysdeps/unix/sysv/linux/alpha/fpu_control.c: File removed.
* sysdeps/unix/sysv/linux/setfpucw.c: Moved to ...
* sysdeps/generic/setfpucw.c: here.
(__fpu_control): Variable removed.
(__setfpucw): Use SET even if zero.
* elf/rtld.c (_dl_start): Don't rely on pointer-to-first-arg hack
for getting the argc/argv/envp block. Instead, make it the argument.
sysdeps/i386/dl-machine.h (RTLD_START): Do that.
sysdeps/m68k/dl-machine.h (RTLD_START): Same.
* sysdeps/alpha/Makefile [subdir elf]: Add -mno-fp-regs to
sysdep-CFLAGS so that _dl_runtime_resolve doesn't have to save them.
Add -mbuild-constants to CFLAGS-rtld.c to that we can bootstrap
without using literal data.
* elf/dl-object.c (_dl_loaded): Variable removed.
(_dl_default_scope): New variable replaces it.
* elf/link.h (_dl_loaded): Remove variable decl; instead define as
macro for _dl_default_scope[2].
(_dl_default_scope): Declare it.
* sysdeps/i386/dl-machine.h (RTLD_START): Use _dl_default_scope[2]
instead of _dl_loaded.
* sysdeps/m68k/dl-machine.h (RTLD_START): Likewise.
* elf/rtld.c (dl_main): Use _dl_default_scope for symbol lookups.

argument.

sysdeps/m68k/fpu/k_cosf.c, sysdeps/m68k/fpu/k_sinf.c,
sysdeps/m68k/fpu/k_tanf.c, sysdeps/m68k/fpu/s_atanf.c,
sysdeps/m68k/fpu/s_frexpf.c, sysdeps/m68k/fpu/s_ilogbf.c,
sysdeps/m68k/fpu/s_isinff.c, sysdeps/m68k/fpu/s_ldexpf.c,
sysdeps/m68k/fpu/s_modff.c: Include the corresponding double
versions with appropriate definitions to get float functions,
instead of defining them directly.
* elf/dl-init.c (_dl_init_next): Take argument, link_map whose
searchlist describes the piece of the DT_NEEDED graph to be
initialized.
* elf/link.h: Update prototype.
* sysdeps/i386/dl-machine.h (RTLD_START): Pass _dl_loaded as argument
to _dl_init_next.
* sysdeps/m68k/dl-machine.h: Likewise.
* elf/dl-deps.c (_dl_open): Pass new object as arg to _dl_init_next.
* elf/dl-lookup.c (_dl_lookup_symbol): Take new arg RELOC_ADDR and
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.
Sun Jun 2 14:56:49 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* elf/dl-lookup.c (_dl_lookup_symbol): Arg NOSELF renamed to NOPLT.
Reject SHN_UNDEF defns iff NOPLT is nonzero.
* elf/link.h (_dl_lookup_symbol): Update prototype and comment.
* elf/dl-runtime.c (fixup): Pass 1 to _dl_lookup_symbol for NOPLT.
* elf/dlsym.c (dlsym): Pass 0.
* elf/rtld.c (dl_main): Likewise.
* elf/dl-reloc.c (_dl_relocate_object: resolve): Second arg R_OFFSET
replaced with NOPLT flag. Pass it through to _dl_lookup_symbol.
* elf/do-rel.h (elf_dynamic_do_rel): Update prototype of RESOLVE arg.
Pass `elf_machine_pltrel_p (R->r_type)' result as NOPLT flag value.
* sysdeps/i386/dl-machine.h (elf_machine_pltrel_p): New macro.
* sysdeps/m68k/dl-machine.h (elf_machine_pltrel_p): Likewise.
* sysdeps/stub/dl-machine.h (elf_machine_pltrel_p): Likewise.
* sysdeps/unix/alpha/sysdep.h (END): Redefine to use .end
directive for both ELF and ECOFF.
(ret): Delete macro. It was a dangerous macro and unnecessary
since the Alpha assemblers recognizes "ret" as a macro themselves.
Thu May 23 02:15:56 1996 David Mosberger-Tang <davidm@azstarnet.com>
* 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.
* 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.
* 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.
* sysdeps/alpha/bsd-_setjmp.S (setjmp): Renamed entry point to
_setjmp.
* sysdeps/alpha/_mcount.S, sysdeps/alpha/bb_init_func.S,

sysdeps/unix/sysv/linux/alpha/pipe.S,
sysdeps/unix/sysv/linux/alpha/sigsuspend.S,
sysdeps/unix/sysv/linux/alpha/sysdep.S: Use END macro instead of
.end directive.
Tue May 28 10:46:04 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/alpha/bsd-_setjmp.S: The function is _setjmp not setjmp.
* sysdeps/alpha/_mcount.S, sysdeps/alpha/bb_init_func.S,
sysdeps/alpha/bsd-setjmp.S, sysdeps/alpha/ffs.S,
sysdeps/alpha/htonl.S, sysdeps/alpha/htons.S, sysdeps/alpha/memchr.S,

sysdeps/unix/sysv/linux/sigsuspend.S,
sysdeps/unix/sysv/linux/alpha/syscall.S,
sysdeps/unix/sysv/linux/alpha/sysdep.S: Remove include of regdef.h.
sysdep.h includes it now. Replace ENTRY by LEAF with appropriate
framesize declaration. Replace "lda pv,sym/jsr pv" by "jsr sym".
Wed Mar 27 10:26:21 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/alpha/setjmp.S: Must establish global pointer before
address of __sigsetjmp_aux can be loaded.
