be0d51d64c * allow $MinEnumSize, $PackSet and $PackRecords to be used with $Push and $Pop

b9ab9e5782 + initial (experimental) implementation of section-based smartlinking for i8086. 
Use -dI8086_SMARTLINK_SECTIONS to enable.

bfdd75eabf + support AB_LOCAL symbols in OMF object files, by implementing support for 
LPUBDEF/LPUBDEF32 OMF records

188e9ff64a * only read the first OMF record in TOmfLibObjectWriter.closefile, since we no 
longer copy the entire file there, so we parse the file only to get the module
  name, and the THEADR record should always be the first record in the OMF file.

3f5577077a * automatically create omf libraries with the smallest page size possible. This 
greatly reduces the size of i8086 snapshots by keeping the amount of padding
  in the library files to the minimum.

345713c1fa * refactored omf library writing, so that the whole library is written in 
TOmfLibObjectWrite.WriteLib, after determining the page size (currently still
  fixed to 512 bytes). Prerequisite for OMF lib page size optimization.

00c6826896 * moved the PageNum property of TOmfLibObjectWriter.TOmfLibDictionaryEntry to 
TOmfLibObjectWriter.TOmfLibObjectModule. Instead, store the module index (in
  FObjectModules) in TOmfLibDictionaryEntry. This is a prerequisite for
  implementing OMF library page size optimization.

4bcfe8dbb2 * refactored TOmfLibObjectWriter, so it keeps all object modules in a 
TFPObjectList. This will allow implementing omf library page size optimization
  later.

af5e6e182d * the TOmfLibDictionaryEntry class in unit owomflib converted to two identical 
nested classes inside TOmfLibObjectWriter and TOmfLibObjectReader. The reason
  is I'm planning to change the class, used in TOmfLibObjectWriter, but not the
  one in TOmfLibObjectReader. And using nested classes keeps things clean and
  avoids exposing implementation details in the interface of the owomflib unit.
* also changed 'private' to 'strict private' in the classes of the owomflib to
  reduce the risk of interference between TOmfLibObjectWriter and TOmfLibObjectReader.

bbbaa39d79 ncginl: another approach to fix the same issue #39184 supposed to address. keep left.resultdef, but try to make the target def always ordinal of an equal size, so it ends up in a data register on m68k

42efddc481 ncginl: in inc/dec, do not use left.resultdef as the dest to force a register location, because if left is a pointer, then an ordinal value might get forced into an address register on m68k, which results in a lot of unnecessary register shuffling to complete the operation

ddf8788c7a m68k: try to generate better code from some pointermath - when the left is an address register and we do add/sub, also allocate an address register as temp, also only require that left and right sizes are same, when right is not a const

e6a8c058e0 * moved the handling of LIDATA OMF records (which currently only produces a 
'LIDATA records are not supported' error) to TOmfObjInput.ReadLeOrLiDataAndFixups

e410a0aefb + support OMF FIXUPP records, containing only THREAD subrecords to occur without 
a preceding LEDATA or LIDATA record (this is allowed by the OMF spec)

002b116322 * use a case statement, instead of 'if', based on the OMF record type in 
TOmfObjInput.ReadLEDataAndFixups. This is to allow (in the future) handling of
  LIDATA records and FIXUPP records without preceding LEDATA/LIDATA. No
  functional changes in this commit.

199b5809a3 * optimize "dynarr := dynarr + [elem]" to "Insert(elem, dynarr, High(SizeInt))" and "dynarr := [elem] + dynarr" to "Insert(elem, dynarr, 0)" (we need to do this in the typecheck of taddnode as otherwise the array constructor is already converted)

6bd99b65bf + emit DW_AT_frame_base dwarf attributes on i8086. Even though the Watcom 
Debugger doesn't require them (it uses BP as the frame register by default),
  the dwarf spec requires that we emit them on i8086, because we also use
  DW_OP_fbreg on i8086.

c5fe78201c + emit DW_OP_bregx dwarf ops for local variables and parameters, relative to BP 
on i8086. This fixes Watcom Debugger not showing them right in memory models,
  where DS<>SS (Watcom seems to ignore the DW_AT_segment attribute for register
  relative variables, even though we emit it correctly :/ )
