-This is the beta release of binutils 2.22.52.0.2 for Linux, which is
-based on binutils 2012 0424 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 2.21.51.0.3 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.
