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. + +Please report any bugs related to binutils 2.18.50.0.9 to +hjl.tools@gmail.com + +and + +http://www.sourceware.org/bugzilla/ + +Changes from binutils 2.18.50.0.8: + +1.
