b17087a645 - removed debug writelns after r30800 
git-svn-id: trunk@30802 -
 2015-05-04 17:13:17 +00:00

f1252d7582 - removed unnecessary setting of TargetMethod and TargetDatum (since these are 
always set in the following 'if' statement) in TOmfRelocation.BuildOmfFixup

git-svn-id: trunk@30801 -
 2015-05-04 17:11:02 +00:00

7923b6142e + finished the internal omf library writer (implementing writing of the library 
dictionary at the and of the file) and enabled it for the i8086 internal asm

git-svn-id: trunk@30701 -
 2015-04-21 23:31:02 +00:00
nickysn
a365da0b44 + added class (empty for now) TOmfLibObjectWriter and hook it as an internal ar 
in the omf internal assembler constructor. Note it is not used yet, because of
  the af_needar assembler flag.

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)

git-svn-id: trunk@30685 -
 2015-04-20 13:15:26 +00:00
nickysn
5a1ce6162b * set the bss, rodata and rodata_norel section alignment to 2 bytes for the i8086-msdos target

git-svn-id: trunk@30679 -
 2015-04-20 00:02:40 +00:00
nickysn
7fca6dd6c1 * set the properties of the dwarf debug info sections in the omf obj writer 
as required by wlink in order to be recognized and handled as debug info
  (i.e. class=DWARF, use32)

git-svn-id: trunk@30636 -
 2015-04-18 00:42:17 +00:00
nickysn
c407f61107 * generate the omf alignment based on the value of SecAlign, instead of 
duplicating the code from sectiontype2align in the TOmfObjSection constructor

 2015-04-15 08:55:19 +00:00

d7416afd88 * override sectiontype2align in the omf writer and set the same alignments as 
the ones, currently produced by nasm

a7e059c875 + support segment relocations in the omf writer

 2015-04-14 22:46:01 +00:00
nickysn
03e8c3ae05 + support RELOC_RELATIVE relocations in the omf object writer, by using omf's 
"self relative" (instead of "segment relative") fixups. "Hello world" and
  fpctris in the small memory model now work (under dosbox, at least) with the
  internal object writer.

8a831f4c7f * always clear segments and groups in the beginning of TOmfObjOutput.writeData, because the same objects is used for creating multiple object files

35e008e44b * TOmfRelocation modified to build the omf FIXUP subrecord later, during 
writeData, when the ObjSection indexes are available; now we fill the proper
  section/segment indexes, instead of hardcoded values.
