06fc6ac491 * fixed threadvar support on linux/i386 and android/i386 after r31639 
(mantis #28672)

3c6aa91a96 * factored out the loading of threadvars in its own method, and put the 
x86-specific part in nx86ld

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so 
that we can use assembler writers with different conventions from the
    currently set target_asm (e.g. an x86 assembler writer for inline assembly
    in LLVM IR)

b3d0197f98 * factored out the output file handling (mostly writing data) from the 
external assembler writer, so we can reuse the archtecture-specific
    writers to write inline assembly in LLVM IR files

bdfd23cc2e + new target switch "FarProcsPushOddBP", which causes the i8086 compiler to push 
odd values of BP if the procedure is far. Enabled this by default for Win16.

92c831c3dd * writing of omf section attributes in the NASM asm writer rewritten to use the 
new functions in unit omfbase (also used by the internal asm)

4061628ffb * the i8086-msdos default code segment (in near code memory models) renamed 
'_TEXT'. This name is used in object modules, produced by Borland C and Open
  Watcom.

0fc1fd6ac1 * replaced current_procinfo.currtrue/falselabel with storing the true/false 
labels of LOC_JUMP in the node's location. This generates some extra jumps
    for short circuit boolean and/or-expressions if optimizations are off, but
    with optimisations enabled the generated code is the same (except for JVM
    because the jump threading optimisation isn't enabled there yet).

5d15a28e75 - reverted workaround from r15939 that hasn't been necessary since FPC 2.6.0, 
since that version already shiped with GNU AS 2.21 (mantis #17337)

1bcc276dcf * remove implicit typecast to extended automatically inserted for trunc/round 
(due to the declaration in the system unit) on x86_64 if this allows us
    to use SSE code instead (mantis #28366)

b21610050f * don't store reusable defs based on other defs from localsymtables into the 
static/globalsymtable. The static/global symtable is stored to the PPU
    while the localsymtables are not, which means we get dangling references
    when reloading such defs from the ppu afterwards

internal object writer

778a678956 * use a 4 byte alignment for the dwarf debug sections on i8086 (not sure if 
that's correct for 16-bit dwarf, but currently the compiler emits 4-byte
  tai_aligns, so setting the section alignment to 4 avoids problems in the
  internal object writer)

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).

3be51e1455 * fixed endless recursion in tabstractrecorddef.contains_float_field() in 
case a record contains an internal typed constant of its own type
    (which happened becuase such a typed constant is also fieldvarsym, solved
     by checking for sp_static) (mantis #27880)
  * fixed several other similar cases in the compiler where we are only
    interested in instance fields, but processed all fieldvarsyms

25a834087e + choose the correct version of "Jcc near" to use on i8086 (386+ or 8086+) 
depending on the specified target cpu type

2cf6852910 + added i8086 instruction entries for Jcc near (which is actually a 386+ 
instruction), that encode it as two i8086 compatible instructions:
    JNcc short +3
    JMP near target

bfd5670cc8 + support new magic code \23 in the internal asm writer - same as \13, but with 
the condition inverted; this will be used to simulate near conditional jumps
  on processors earlier than 386 (i.e. "Jcc near target" will be encoded as
  "JNcc short +3; JMP target")
