052af9200e * support external declarations for compilerprocs 
o since there is no separate implementation for them, we have to immediately
     convert the symbol to lower case after parsing the declaration

0eb1cd157a * don't subtract two from the end of the stack segment when calculating the 
initial SP value - seems to be wlink compatible

2431b6e63b * i8086-msdos internal linker: use a different approach for finding the stack 
segment - either its class name must be 'STACK' (wlink compatible) or its
  combine type must be scStack (tlink compatible)

d7f08866e5 * use the TMZExeOutput.MZFlatContentSection property in TInternalLinkerMsDos.GetTotalSizeForSegmentClass 
instead of finding the exe section by name

449506ffb7 + write mz exe section data

cff94639d5 * i8086-msdos internal linker: improved handling of the _edata and _end internal

173713ce57 * preserve original order (as specified in the link script) of omf sections with 
the same name. This ensures that the startup code always comes first, which is
  important for .com files

fa9a1f706b + i8086-msdos internal linker: calculate the final segments and groups locations 
in memory (incl. segment bases) before DoRelocations; list segments and groups
  in the map file as well

5dc42404cf * capitalize omf segment class names, as that's how other 16-bit compilers write them

 2015-08-22 19:07:04 +00:00
nickysn
e09ab50724 * capitalize the group name 'DGROUP' in the generated omf object files, because 
that's how it is usually written by other 16-bit compilers

git-svn-id: trunk@31369 -
 2015-08-22 16:28:36 +00:00

70677e3e44 + added a descendant class for omf section groups, which adds base address, size 
and a method to calculate these new fields

9aeb94676c + added virtual method to tobjsection for returning a string representation of 
the section's base address for the internal linker map file
* implemented it for omf sections to return the address in 'seg:ofs' format

git-svn-id: trunk@31359 -
 2015-08-21 16:21:16 +00:00
nickysn
a762532ae1 * changed the MemPos field in TObjSection and TExeSection from aword to qword: 
1) aword follows the ALU size of the CPU, not the address size
  2) it is already qword in TExeOutput and its methods and there's already
     MaxMemPos to check if the limits of the platform/exe format have been
     exceeded

808b5dfb78 * allow gaps between LEDATA records, as nasm seems to produce them. They're 
automatically filled with zeros. This fixes reading of the tiny memory model
  startup code object module by the i8086-msdos internal linker.

7d586df038 * override DoRelocationFixup in TMZExeOutput - doing nothing for now, but
