Slackware 14.1 x86_64 stable is released!

It's been another interesting release cycle here at Slackware bringing
new features like support for UEFI machines, updated compilers and
development tools, the switch from MySQL to MariaDB, and many more
improvements throughout the system.  Thanks to the team, the upstream
developers, the dedicated Slackware community, and everyone else who
pitched in to help make this release a reality.

The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a
dual-sided
32-bit/64-bit x86/x86_64 DVD.  Please consider supporting the Slackware
project by picking up a copy from store.slackware.com.  We're taking
pre-orders now, and offer a discount if you sign up for a subscription.

Have fun!  :-)

This is the beta release of binutils 2.23.52.0.1 for Linux, which is
based on binutils 2013 0226 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 2.23.52.0.1 release, when creating executables, BFD
linker will issue an error for undefined weak reference which is
defined in a shared library from DT_NEEDED. Previously BFD linker
will silently include the shared library from DT_NEEDED.
Starting from the 2.21.51.0.3 release, you must remove .ctors/.dtors
section sentinels when building glibc or other C run-time libraries.
Otherwise, you will run into:
http://sourceware.org/bugzilla/show_bug.cgi?id=12343
Starting from the 2.21.51.0.2 release, BFD linker has the working LTO
plugin support. It can be used with GCC 4.5 and above. For GCC 4.5, you
need to configure GCC with --enable-gold to enable LTO plugin support.
Starting from the 2.21.51.0.2 release, binutils fully supports compressed
debug sections. However, compressed debug section isn't turned on by
default in assembler. I am planning to turn it on for x86 assembler in
the future release, which may lead to the Linux kernel bug messages like
WARNING: lib/ts_kmp.o (.zdebug_aranges): unexpected non-allocatable section.
But the resulting kernel works fine.
Starting from the 2.20.51.0.4 release, no diffs against the previous
release will be provided.
You can enable both gold and bfd ld with --enable-gold=both. Gold will
be installed as ld.gold and bfd ld will be installed as ld.bfd. By
default, ld.bfd will be installed as ld. You can use the configure
option, --enable-gold=both/gold to choose gold as the default linker,
ld. IA-32 binary and X64_64 binary tar balls are configured with
--enable-gold=both/ld --enable-plugins --enable-threads.
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.
