5c67fcc43f + change always floating point divisions into multiplications if they are a power of two, 
this is an exact operation so it is always allowed

d8c898742a * handle the fact that records containing a single extended value are 
returned on the x87 fpu stack on x86-64
   o also handle the fact that this means that we'll generated float
     loads/stores with OS_128/OS_F128 in case the surrounding record
     is padded to a multiple of its alignment

6712954607 * correctly handle X86_64_X87UP_CLASS getting merged with another class and 
becoming X86_64_SSE_CLASS/X86_64_INTEGER_CLASS/... This is not defined in
    the ABI because there sizeof(extended)=16 and hence the class of the upper
    eightbyte of the extended value can never be merged with the class of
    another field (except in a union, but then the class of the lower
    eightbyte will also be overwritten).

    Handle it the same as when the lower eightbyte class of an extended in an
    aggregate gets changed into something else: pass everything in memory
    (part of mantis #26993)

8244d366d0 - moved deallocation of NR_PIC_OFFSET_REG from the x86_64 to the i386 code

dc628b8969 * x86: Completely skip instructions that do not exist for target CPU bit width. The existing behavior of writing mnemonics and properties but no encoding allows an invalid instruction to be recognized by assembler reader or even generated by compiler, but it but won't assemble anyway.

d88d644925 + support for FMA intrinsic: if there is no hardware support, the compiler throws an error. 
Currently it is implemented only for x86-CPUs supporting the FMA extension. While it would
  be possible to implement it in software or simulate fma(<single>,<single>,<single>) using
  double operations, it makes no sense in my opinion to do so.

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls
