ae92973196 + added support for the retw, retnw, retfw, retd, retnd, retfd, retq, retnq and 
retfq x86 instructions. These are variants of the ret instruction with the
  return offset size set explicitly, e.g. retfw is a 16-bit far ret (i.e. pops
  a 16-bit offset and a 16-bit segment), retfd is a 32-bit far ret (pops a
  32-bit offset, followed by a 16-bit segment), etc.

e58bad8eef + check for the 'pop cs' instruction in the x86 inline assembler and print a 
warning (on the i8086 target) or an error (on i386 and x86_64) when this
  instruction is used (because it only works on 8086 and 8088 CPUs)

2357ca1fe6 * Fixed size suffix generated for CVTSI2SS, CVTSI2SD, VCVTSI2SS, VCVTSI2SD instructions. Mantis #31550. 
* tasm2.pp already detected this bug if run with -al option. Added a copy of tasm2.pp and configured it with -al, so it is run daily on all suitable machines.

8173efff3e * x86 asm reader: Don't copy operand size to instruction size for MOVSS and VMOVSS, because it is different for source and destination. Fixes breakage caused by fixing memory size of those instructions (Mantis #29954 and Mantis #29957). 
+ Tests are extended to check that both OPR_LOCAL and OPR_REF memory operands compile without warnings as source and destination, in both Intel and AT&T syntax.

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol(): 
it was AT_NONE, which is invalid and should never be used
  * explicitly pass the correct value for all calls to those methods elsewhere
    in the compiler

8d5cc3dfa4 * (extended and modified) patch by Emelyanov Roman to add suport of RDRAND, RDSEED and TSX instructions set, resolves issue #29893. 
In comparison with the original patch, support for a i386 has been added as well as a test program. 
  Further, a small issue with xbegin has been fixed

5c8965fea5 * in the inline asm reader, treat [var] reference as "word" instead of "dword" 
when "var" is of dword size. This fixes spurious generation of a $66 prefix
  and makes the code consistent with what Tx86Operand.SetSize does (and what is
  then used for checking the operand sizes of all operands of the instruction in
  Tx86Instruction.CheckOperandSizes).

42d251da1c - x86 assembler readers: cleaned out operand swapping code. Operands of TInstruction are kept in AT&T order, Intel reader attaches operands right-to-left. It was effectively the same way before the change (except Intel reader attaching operands left-to-right, followed by a single swap), operand order checks all over the place were just reducing readability.

4d0e4e1b56 * treat "[var + rip]" in intel assembler mode as addr_pic_no_got on x86-64 
(mantis #22665)

    for GOT-relative accesses on x86-64, + give an error when trying to do
    this on win64 (it doesn't have a GOT)
  * moved code that give a warning when using GOT-relative accesses to
    static data on x86-64 from the AT&T reader to rax86 so it's also
    active for the Intel assembler reader
  + added warning when not using GOT-relative accesses (but plain
    RIP-relative instead) to global data on non-Win64 x86-64
