This is the beta release of binutils 2.18.50.0.5 for Linux, which is
based on binutils 2008 0314 in CVS on sourceware.org plus various
changes. It is purely for Linux.

All relevant patches in patches have been applied to the source tree.
You can take a look at patches/README to see what have been applied and
in what order they have been applied.

Starting from the 2.18.50.0.4 release, the x86 assembler no longer
accepts

        fnstsw %eax

fnstsw stores 16bit into %ax and the upper 16bit of %eax is unchanged.
Please use

        fnstsw %ax

Starting from the 2.17.50.0.4 release, the default output section LMA
(load memory address) has changed for allocatable sections from being
equal to VMA (virtual memory address), to keeping the difference between
LMA and VMA the same as the previous output section in the same region.

For

.data.init_task : { *(.data.init_task) }

LMA of .data.init_task section is equal to its VMA with the old linker.
With the new linker, it depends on the previous output section. You
can use

.data.init_task : AT (ADDR(.data.init_task)) { *(.data.init_task) }

to ensure that LMA of .data.init_task section is always equal to its
VMA. The linker script in the older 2.6 x86-64 kernel depends on the
old behavior.  You can add AT (ADDR(section)) to force LMA of
.data.init_task section equal to its VMA. It will work with both old
and new linkers. The x86-64 kernel linker script in kernel 2.6.13 and
above is OK.

The new x86_64 assembler no longer accepts

        monitor %eax,%ecx,%edx

You should use

        monitor %rax,%ecx,%edx

or
        monitor

which works with both old and new x86_64 assemblers. They should
generate the same opcode.

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 2.16.90.0.1 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.
