This release fixes an alpha bug and a PPC bug.

H.J. Lu (
This is the beta release of binutils for Linux, which is
based on binutils 2.9.1 plus Linux/ARM support, some x86 assembler
changes, some PPC bug fixes, some alpha bug fixes and an exception
frame optimization bug fix.

Due to the exception frame optimization bug fix, it is highly
recommended that you recompile all your C++ codes. Otherwise,
exception handling may not work right when an exception is thrown.

Since I no longer have machine running libc 5, starting from this
release, there will be no pre-compiled binaries for libc 5.

I am planing to release this to the public as the final public release
for binutils based on binutils 2.9.1 and the current 16-bit
x86 assembler changes. The future release will be based on the binutils
snapshot, which has a different approach for 16-bit x86 assembly code.
Please test it as much as you can.

There was some problem on Linux/alpha. The binaries generated by the
new binituls may not run correctly on Linux/alpha. It turned out it was
a bug in the alpha dynamic linker in glibc 2.0.6. The current glibc 2.1
and glibc 2.0.7 should be ok.

This release should work on linux/x86/alpha. There are some ELF bug
fixes. But I don't know if it fixes all the bugs reported on
linux/sparc, Linux/MIPS and linux/PPC. I'd like to hear reports on them.
I'd like to release it to public soon. Please test it as much as you

Changes from binutils

1. A MIPS assembler ".align" bug is fixed.
2. bfd.h, bfd.h and bfdlink.h are included in the binary package.

Changes from binutils

1. 2 x86 16bit mode assembler bugs, "ret" and "movb $35,0x4(%di)", are

The .plt format that the Alpha was using was not thread safe.  So I 
changed it.  The new format is *not* binary compatible with the old,
thus you must use glibc 2.0.4 to get an that can understand it.

Note that the new knows how to deal with the old .plt format, so
old libraries will still work, but they should be relinked eventually
for performance reasons.

The file list:

1. binutils- Source code.
2. binutils- Patch against the previous
   beta source code.
3. binutils- Precompiled Linux/x86 binaries
   for libc 6 (glibc 2.0.5c or above).
4. binutils- Precompiled Linux/alpha binaries
   for glibc 2.0.7 or above.

The primary ftp sites for the compiler/C library:


The beta directory is in private/tofu under the GCC directory.

To install the binary package, please follow the procedure very closely.
Please backup/save all the files you are instructed to delete and you
should do
	gzip -dc binutils- | tar tvvf -
	gzip -dc binutils- | tar tvvf -
to see what is in there.
Please do back up before you remove things.

To install for libc 6 (glibc 2.0.5c or above), PLEASE DO
1. su root
2. cd /
3. rm -f /usr/bin/encaps /usr/bin/nm
4. gzip -dc binutils- | tar xvvf -
5. ldconfig
Now you have the new gas/binutils under /usr/bin and
/usr/ix86-linuxaout/bin. You have to use
/usr/ix86-linuxaout/bin/ld -m i386linux
if you want to use a.out as and ld directly.
To install for alpha, PLEASE DO
1. su root
2. cd /
3. gzip -dc binutils- | tar xvvf -
4. ldconfig
I have changed the target names for Linux/x86 and Linux/x86 (a.out)
to ix86-linux and ix86-linuxaout respectively. The precompiled
binaries are installed under /usr/ix86-linux and /usr/ix86-linuxaout.
You should make appropriate symbolic links if you have a different
name for the Linux/x86 target, like i586-unknown-linux.

The target name for Linux/alpha is alpha-linux. The precompiled alpha
binaries are installed under /usr/alpha-linux. You should make
appropriate symbolic links if you have a different name for the
Linux/alpha target, like alpha-redhat-linux.

If you have an old linux library in the a.out format and you cannot
obtain the newer version in the ELF format for whatever reason, you
can try "objcopy --remove-leading-char" on the a.out library and see
if it can link with your code in ELF.
