1b66995754 * factored out check to determine whether a variable can be subscripted in
inline assembly, and fixed check after r35959 (mantis #32318)
   o can also subscript parameters passed by value on the stack
   o can also subscript local variables, the parameters passed by reference
     that are subsequently copied into a local

a8232ac477 + added warning if source or destination for x86 string instructions isn't
specified to be (%esi) or (%edi), when using at&t syntax assembler (this is
  not considered an error by intel syntax assemblers, so we're not adding a
  warning there, for now)

  uses the new helper functions

0fb79946a5 + added support for the parameterized versions of the x86 string instructions
(movs, cmps, scas, lods, stos, ins, outs) in the inline asm of the i8086, i386
  and x86_64 targets. Both intel and at&t syntax is supported.
* NEC V20/V30 instruction 'ins' (available only on the i8086 target, because it
  is incompatible with 386+ instructions) renamed 'nec_ins', to avoid conflict
  with the 186+ 'ins' instruction.

4cf2a2672a changes to fix #32043
* changed most of the variables in the assembler readers used to store constants from aint to tcgint 
  as aint has only the size of the accumular while some CPUs (AVR) allow larger constants in instructions
+ allow access to absolute symbols with address type in inline assembler
* allow absolute addresses in avr inline assembler
+ tests

aa82e00615 * fixed check to determine whether a record parameter can be subscripted
directly in inline assembly: that's only possible if it's a register
    parameter where the address of the record was passed (rather than the
    record itself), or if a parameter has been explicitly typecasted in
    Intel-style assembly using ".size"

870fda34d5 * x86 AT&T reader and writer: cleaned up usage of attsufMM suffix:
* It is now only used to select size of vector instructions (i.e. 128 or 256 bits)
  * Scalar instructions reverted to use attsufINT suffix (selecting between 32 or 64 bits).
  * Additionally, vcvtsi2sd and vcvtsi2ss with rm64 operand are x86_64 only.

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol():
it was AT_NONE, which is invalid and should never be used

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)
  + support "[var wrt ..gotpcrel]" nasm/yasm syntax in intel assembler mode
    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

92adf34e3f * Tighten rules for accepting ATT suffixes, no longer accept FPU suffixes for integer instructions and vice versa. Resolves #18900.
* tb0267.pp required patching due to 'fildw' instruction at line 72, which is rejected by GAS. Before this commit, FPC was silently converting it to 'filds', so it went unnoticed. Now FPC rejects 'fildw' like GAS does.

f97f223de6 x86_64 assembler reader improvements:
+ Added new value TAttSuffix.attsufINTdual, assigned it to movsX and movzX instructions
* Moved suffix-to-size translation tables from rax86att.pas to itcpugas.pas
+ Added x86_64 specific suffix-to-size translation, enabling BQ and WQ suffixes (LQ seems unnecessary at the moment)
* Fixed logic of tx86attreader.is_asmopcode so it only assigns dual suffix to instructions that explicitly allow it. This disambiguates cases like movsbq=movs+bq vs. cmovbq=cmovb+q
* As a net result: movz[bw]q and movs[bw]q now compile for x86_64; cmovbw and cmovbl which were incorrectly handled for i386 are now fixed.
+ Test for correct assembling of cmov.

8b0301409a + i386/iphonesim target for the new iPhoneSimulator in Xcode 3.2.4 and
later: the same as i386/darwin, except
      a) uses the non-fragile Objective-C ABI/runtime
      b) does not require stubs for direct calls/jumps (not required for
         i386/darwin under 10.6 and later either, but still generated
         there for backwards compatibility)
      c) only the same packages are enabled as for ARM/Darwin
      d) MacOSAll is compiled specifically for the iPhoneSimulator SDK
    This target also defines the symbol "darwin" apart from the target
    name "iphonesim" for source code compatibility reasons.

     never triggered, and I copied that part...)
