* sysdeps/m68k/dl-machine.h (RESOLVE): New macro, defined
differently based on [RTLD_BOOTSTRAP].
(elf_machine_rela): Use it instead of the fn ptr arg directly.
* sysdeps/alpha/dl-machine.h (elf_machine_rela) [RTLD_BOOTSTRAP]:
If this is defined, don't declare _dl_rtld_map as weak, and
don't check for MAP pointing to it. RESOLVE is always null in this
case, so test with #ifdef instead of if.
* libc-symbols.h (symbol_set_declare): Use weak_extern instead of
weak_symbol.
* csu/initfini.c (_init): Likewise.
* locale/setlocale.c (DEFINE_CATEGORY): Likewise.
* misc/efgcvt_r.c: Likewise.
* sysdeps/alpha/dl-machine.h (elf_machine_rela): Likewise.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Likewise.
* sysdeps/unix/sysv/linux/alpha/init-first.h,
sysdeps/unix/sysv/linux/m68k/init-first.h,
sysdeps/unix/sysv/linux/i386/init-first.h: New files.
* sysdeps/unix/sysv/linux/init-first.c: Use platform-dependent
init-first.h to make abstract machine dependent parts of
initialization.
* sysdeps/alpha/dl-machine.h (elf_machine_rela): The Alpha's
address-of operation and plt format conspire to require all
dynamic relocs to be resolved to actual symbols not plt entries.
* sysdeps/alpha/dl-machine.h (elf_machine_rela): The Alpha's
address-of operation and plt format conspire to require all
dynamic relocs to be resolved to actual symbols not plt entries.
* sysdeps/alpha/dl-machine.h (ELF_MACHINE_RUNTIME_TRAMPOLINE):
A .plt entry now loads the .rela.plt offset directly rather
than making us calculate it.
* sysdeps/alpha/dl-machine.h (elf_alpha_fix_plt):
Changed to a 12-byte PLT entry to remove dependency on $gp.
Take a new got_addr parameter.
(elf_machine_rela): Pass the new parameter.
(ELF_MACHINE_RUNTIME_TRAMPOLINE): Do arithmetic for 12-byte PLT.
(RTLD_START): Do normal linkage with program entry.
* 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/sysv/linux/alpha/sysdep.S,
sysdeps/unix/sysv/linux/alpha/brk.S,
sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S,
sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S,
sysdeps/unix/sysv/linux/alpha/llseek.S,
sysdeps/unix/sysv/linux/alpha/sigsuspend.S,
sysdeps/unix/sysv/linux/alpha/syscall.S: Rename syscall_error to
__syscall_error to avoid intruding application name space.
* 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).
* sysdeps/unix/sysv/linux/alpha/sysdep.S,
sysdeps/unix/sysv/linux/alpha/brk.S,
sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S,
sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S,
sysdeps/unix/sysv/linux/alpha/llseek.S,
sysdeps/unix/sysv/linux/alpha/sigsuspend.S,
sysdeps/unix/sysv/linux/alpha/syscall.S: Rename syscall_error to
__syscall_error to avoid intruding application name space.
* 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/sysv/linux/alpha/sysdep.h: Rename __NR_get?id
to SYS_get?id so that syscall stubs in sysdeps/unix define
these syscalls in terms of getxpid/getxuid/getxgid.
* 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/alpha/fpu/fpu_control.h: here. Fixed copyright.
* 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.
* sysdeps/m68k/dl-machine.h (elf_machine_rela): Fix type of reloc
argument.
[case R_68K_32]: Check for resolve being null.
(RTLD_START): Add missing label.
* sysdeps/m68k/fpu/e_acosf.c, sysdeps/m68k/fpu/e_fmodf.c,
sysdeps/m68k/fpu/k_cosf.c, sysdeps/m68k/fpu/k_sinf.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.
