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.
