0a01c0c76f * autoswitch to writing 32-bit SEGDEF OMF records if there's a need to encode a 
32-bit segment length

8c842c1337 * changed the type of the 'size' parameter of TOmfObjOutput.AddSegment to 
TObjSectionOfs instead of aword

ca50b14e21 * set the omf section size limit to 32-bit for the dwarf debug sections

nickysn
065a7b63d9 * changed the TObjSectionOfs type to be longword on i8086 
+ introduced the TObjSection.SizeLimit property. This will allow setting
  different size limits for different sections (e.g. 32-bit for the dwarf
  sections, 16-bit for the regular code and data sections on i8086).

f9748e928b * also changed the type of the 'DataPos' parameter of TObjData.layoutsections to TObjSectionOfs

 2018-05-21 16:48:56 +00:00
nickysn
04129b8c6e + introduce the TObjSectionOfs type - an unsigned integer, representing an 
offset in an obj file section on the current platform; equal to PUInt for now,
  but will probably change to LongWord on i8086, in order to support 32-bit
  sections (needed for dwarf debug info or when linking with 32-bit object files
  in a mixed 16-bit/32-bit application, while using the internal linker)

d1cdd8be7c * do not emit padding bytes after the dwarf arange header on i8086 for 
compatibility with Open Watcom (also, the dwarf spec is not very clear about
  the alignment requirements on segmented architectures, so that's why we do
  this by default, instead of putting it behind a -go debug switch)

git-svn-id: trunk@39075 -
 2018-05-20 22:50:46 +00:00
nickysn
1a2f364e68 * use 32-bit address_size in the dwarf arange sections on i8086 (for Open Watcom 
compatibility)

651571c00f + added comments, indicating where we emit the address_size and segment_size 
fields of the dwarf arange header

a12622e06f * use 1-byte alignment instead of 4-byte alignment for the OMF dwarf sections 
(otherwise the alignment screws up the dwarf debug info)

dcfe1cae13 * fix 4265 cases where the index resolved a lemma that had a link= property. 
Mantis #32325
 * adds a warning for the cases that are fixed. If generation logs are saved, this makes it easy to check if new problems are related to this fix.

git-svn-id: trunk@39060 -
 2018-05-20 15:48:58 +00:00
nickysn
a7f5a69000 + added an address size parameter to lnfodrwf.ReadAddress(); pass the expected 
address size, as taken from the dwarf header structure

value, according to the x86 pointer type

git-svn-id: trunk@39057 -
 2018-05-20 14:42:17 +00:00
nickysn

 2018-05-20 13:41:10 +00:00
nickysn
2c000d1e74 * processaddress's type changed to word on i8086 (ptruint changes size between 
memory models and we only need the offset; the segment is tracked separately)
+ introduce texefile.processsegment on i8086
* initialize processaddress and processsegment properly on i8086-msdos (for .exe
  files; .com files are not supported yet)
