6cd88a24dc * release al/ax/eax immediately after the 'in', before (instead of after) moving 
it to the destination imaginary register. This generates better code.

fdc896ad0a + inline support for the x86 'in' and 'out' instructions. Currently only enabled 
in the i8086-msdos 'ports' unit, but will be enabled on other targets (e.g.
  go32v2) in the future as well. 32-bit 'in' and 'out' not inlined on i8086, but
  will be on i386 and x86_64.

a38e9ff12e * if an include file name ends in dot, and the file is not found, also search 
for the file name without the dot. So, for example, if the code contains
  {$I MPAL256.} and 'MPAL256.' is not found, search also for 'MPAL256'

f036e67d8f * fixed the reading of OMF groups by the internal linker. Previously, it only 
worked, when the files had only one group, called 'DGROUP'.

45337b67fe + when using the i8086 with section based smartlinking, create OMF section 
groups, named 'CGROUP' or 'CGROUP_UNITNAME', which include all the code
  sections, that need to be put in the same segment

f07658d3dc * get rid of TOmfRelocation.GetGroupIndex; instead, read the index property of 
the group object. This adds support for groups, other than DGROUP, when
  writing omf relocations.

d3db9e101a * don't check for the presence of the group in TOmfObjOutput.AddSegmentToGroup, 
because, it is no longer possible for it to not be present (all the groups
  are added beforehand now)

9a0eca52cb * changed the type of TOmfObjSection.PrimaryGroup from string to 
TObjSectionGroup, so instead of holding the group's name, it now points to the
  TObjSectionGroup object, from which you can retrieve its name or any of the
  other fields and properties it contains

f4e26f382f + added an 'index' field to TObjSectionGroup, specifying the index of the group 
in the object file (similar to TObjSection.index, but for groups, instead of
  sections). Set the new index field, when writing .obj files with the internal
  omf object writer.
