Subject: The Linux binutils 2.16.90.0.2 is released

From: "H. J. Lu" <[email-masked]>
Date: Fri, 29 Apr 2005 17:04:13 -0700

This is the beta release of binutils 2.16.90.0.2 for Linux, which is
based on binutils 2005 0429 in CVS on sources.redhat.com plus various
changes. It is purely for Linux.

The new i386/x86_64 assemblers no longer accept instructions for moving
between a segment register and a 32bit memory location, i.e.,

	movl (%eax),%ds
	movl %ds,(%eax)

To generate instructions for moving between a segment register and a
16bit memory location without the 16bit operand size prefix, 0x66,

	mov (%eax),%ds
	mov %ds,(%eax)

should be used. It will work with both new and old assemblers. The
assembler starting from 2.16.90.0.2 will also support

	movw (%eax),%ds
	movw %ds,(%eax)

without the 0x66 prefix. Patches for 2.4 and 2.6 Linux kernels are
available at

http://www.kernel.org/pub/linux/devel/binutils/linux-2.4-seg-4.patch
http://www.kernel.org/pub/linux/devel/binutils/linux-2.6-seg-5.patch

The ia64 assembler is now defaulted to tune for Itanium 2 processors.
To build a kernel for Itanium 1 processors, you will need to add

ifeq ($(CONFIG_ITANIUM),y)
	CFLAGS += -Wa,-mtune=itanium1
	AFLAGS += -Wa,-mtune=itanium1
endif

to arch/ia64/Makefile in your kernel source tree.

Please report any bugs related to binutils 2.16.90.0.2 to [email-masked]

and

If you don't use

# rpmbuild -ta binutils-xx.xx.xx.xx.xx.tar.bz2

to compile the Linux binutils, please read patches/README in source
tree to apply Linux patches if there are any.
