* objcopy.c (strip_main): Revert the change made on 2001-05-30
by accident.
(copy_main): Apply the the change made to strip_main on
2001-05-30 by accident.
strip now passes the argument list as documented.

ChangeLog for this change (which was never committed to the master
GCC sources; the bug still exists in GCC 3.x!):

* config/mips/mips.h (FUNCTION_PROFILER): Deal with
the case where jal is expanded as a macro.
This is done by removing the .reorder/.noreorder, and moving the
call to _mcount to after the stack adjust, thereby letting the
assembler deal with the delay slot, etc.
This fixes profiling with libraries built -mabicalls (default on
NetBSD).
I can't believe how long this problem has been discussed-but-not-fixed
on the GCC mailing list...
into the mmap'd region. (reviewed by thorpej.)
This is done to facilitate use as a host tool on not-necessarily-NetBSD
host systems. Specifically, it works around problems discovered on
linux (mostly tested on 2.4.2-smp / RH 7.1, but also seen on other
variants) in which mmap(...MAP_SHARED...) on NFS files doesn't work
properly:

case:
MKBFD If set to "no", disables building of libbfd, libiberty,
and all things that depend on them (binutils/gas/ld, gdb,
dbsym, mdsetimage).
MKGDB If set to "no", disables bulding of gdb.
MKGCC If set to "no", disables building of gcc and the
gcc-related libraries (libg2c, libgcc, libobjc, libstdc++).
These are useful for building platforms for which either of the following
situations are true:
(1) You have no userland from which to run toolchain2netbsd
in order to build the appropriate toolchain build framework.
(2) The platform which you are building requires a newer set
of tools than are currently in the tree (e.g. x86-64, ia64).
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
1) There is already a destructor that does this. The atexit() is superfluous.
2) If libstdc++ is loaded dynamically by dlopen() and then is removed by
dlclose(), the pointer is no longer valid and the program would core dump
at exit() time. (This caused xmms to core dump at exit when xmms-sid was
installed, for example.)
NOTE: THIS NEEDS TO BE APPLIED TO THE `TOOLCHAIN' VERSION.
* jump-format jumps: the target is in RB, so use the RB bits in
the insn, not the RA bits.
* branch-format displacements are 21 bits; extract all of them, and
sign-extend correctly.
* For conditional branches, we need to determine whether or not
the branch is actually taken.
and ASM_FINISH_DECLARE_OBJECT macros in <alpha/netbsd.h>,
and remove ASM_DECLARE_FUNCTION_NAME, ASM_DECLARE_OBJECT_NAME,
ASM_FINISH_DECLARE_OBJECT, and ASM_DECLARE_FUNCTION_SIZE from
<netbsd.h>.
* Regen files with proper OS names and version numbers.
* Clean up toolchain2netbsd somewhat, to get it ready to be cross-host
compatible (more work to be done here, but it's getting closer).
* Add framework for gdbreplay and gdbserver, but hold off on enabling these
by default until low-nbsd.c is verified to work everywhere.
address parts of PR toolchain/14896. This header file is nonstandard
(and doesn't even exist in gcc 3.0); an out-of-the-box gcc build also
doesn't provide the missing functions. So just drop the .h completely.
