0a94f8fc08 + parse the IMPDEF record in TOmfObjInput.ReadImpDef 
git-svn-id: trunk@42346 -
 2019-07-09 12:31:11 +00:00
nickysn
eea3eb1a8e + introduced the TOmfRecord_COMENT_IMPDEF class. Use it to encode the IMPDEF 
records instead of encoding them directly.

9fe80d7416 + use the new CC_OmfExtension_IMPDEF constant instead of the direct magic value 
when writing IMPDEF records

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

git-svn-id: trunk@39279 -
 2018-06-22 17:00:23 +00:00
nickysn
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

git-svn-id: trunk@39277 -
 2018-06-22 15:02:39 +00:00
nickysn
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.

c8fc7c84c8 * avoid adding a section to a group twice in TOmfObjData.createsection 
* add all sections, belonging to a group directly inside TOmfObjOutput.AddGroup,
  based on the TObjSectionsGroup.members array

git-svn-id: trunk@39275 -
 2018-06-21 21:14:54 +00:00
nickysn
8a34bd22b8 * pass a TObjSectionGroup object as parameter to TOmfObjOutput.AddGroup, instead 
of the group name

git-svn-id: trunk@39273 -
 2018-06-21 20:45:52 +00:00
nickysn
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)

git-svn-id: trunk@39272 -
 2018-06-21 20:33:24 +00:00
nickysn
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

git-svn-id: trunk@39271 -
 2018-06-21 16:28:06 +00:00

42f06acaeb + also create the primary section group and add the newly created section to it 
in TOmfObjData.createsection

git-svn-id: trunk@39270 -
 2018-06-21 16:14:42 +00:00
nickysn
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.

git-svn-id: trunk@39269 -
 2018-06-21 15:51:58 +00:00
nickysn
ab47c8b899 + introduce the omf_section_primary_group function. Use it instead of 
section_belongs_to_dgroup, to allow sections to belong to groups, other than
  dgroup.

 2018-06-21 13:21:53 +00:00

5eb69edf9e + support segments (sections) with a primary group, other than 'DGROUP' in the 
OMF internal object writer

7fcec8460f + parse OMF COMENT records when reading object files and produce error messages 
for the records that are not supported, but are important for the executable
  being produced (such as weak/lazy externals, etc.)

3aff9d6735 * set MemPos to 0 for each debug .MZ section. This fixes all references within 
the debug sections themselves.

84b5265312 + append a TIS trailer after the debug ELF (this helps the watcom debugger find 
the beginning of the ELF debug image)

480eedac9f * fix/pretty print the segment and group list with too long segment/group/class 
names in the linker map file, produced by the i8086 internal linker

8af56ad6c8 * fixed silly (caused by copy/paste) bug when writing elf section contents in the dwarf debug binary, produced by TMZExeOutput.writeDebugElf

11cf2a6996 * emit a warning, when encountering an omf reference to a section, that has been 
removed due to smartlinking

nickysn
239fb25179 + assign an MZExeUnifiedLogicalSegment object to the OMF dwarf sections, so that 
OMF relocations work on them too

git-svn-id: trunk@39223 -
 2018-06-14 16:03:05 +00:00
nickysn
7103e3cb5c + set the oso_debug section flags when reading an OMF section, which belongs to 
the 'DWARF' class

git-svn-id: trunk@39222 -
 2018-06-14 15:27:08 +00:00
nickysn
c56ebad183 + implemented writing of dwarf debug info (by calling writeDebugElf) in 
TMZExeOutput.writeData. Note that writing i8086 debug info with the internal
  linker is still disabled (i.e. it switches to external linking) in 
  options.TOption.checkoptionscompatibility

 2018-06-14 14:30:59 +00:00

29b3ec3fdb * call MaybeSwapHeader and MaybeSwapSecHeader in TMZExeOutput.writeDebugElf, so 
the debug ELF file is generated with the correct endianness

git-svn-id: trunk@39218 -
 2018-06-14 13:02:54 +00:00
nickysn
daa47f4b7f + completed the internal debug ELF writer in TMZExeOutput.writeDebugElf (not

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

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

 2018-06-04 14:20:07 +00:00

02fc2827e0 * TOmfObjInput.ReadLEDataAndFixups renamed 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)

git-svn-id: trunk@39169 -
 2018-06-04 14:00:36 +00:00
nickysn
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.

 2018-05-30 15:49:27 +00:00
nickysn
2fb73de404 + support reading OMF files with THREAD FIXUPP subrecords; note that fixups, 
determined by thread are still not yet implemented

f505718e6c + started implementing TMZExeOutput.writeDebugElf; nothing is written yet, only 
the elf header fields are filled with the values, generated by wlink
