I'm building a dos16 program with omf objects.
1. MS Link 5.63 can align some segments with /ALIGN option. But, MS Link 5.63 ignores /Align for MS-DOS programs. http://web.sau.edu/lilliskevinm/csci240/masmdocs/envtools/22LMAETC13.pdf (p.475) 2. Watcom dos16 linker (wlink) can't support alignment for dos16. http://openwatcom.mirror.fr/manuals/1.5/lguide.pdf (p.23) I need a dos16 linker which can load some segments into the 4KB aligned address. Any idea for this? |

1'000'000'000 linkers at your own risk, I don't link myself. |

Example: Code: START: ; some code... org START + ((($-START)/16)*16)+16 ; Code-Alignment NEXT: ; Any code here will be placed forward to the next address that can be divide by 16...(or any other divisor that fit an alignment(accept 4096) that we want to use instead). Edit: Maybe "JLok" is a linker for to control those placement. http://exec.h1.ru/docs/os-devel-faq/os-faq-linker.html Linkers :: JLoc JLoc is written by John Fines. "This program is a linker/locator for use when you need more control over placement of sections within the image, than a standard linker provides." JLoc can be tricky to use for first timers. Carefull reading of the documentation is required. Its not a get-up-and-go linker like all the other linkers. JLoc _requires_ you to write a custome script for each "executable" image you want to link. JLoc gives you flexibility over HOW the object files are linked, regarding loaded addresses and so-forth. JLoc can be obtained here, http://www.erols.com/johnfine/ needs more review!! Pros * Supports OMF/OBJ, DJGPP/COFF * Supports 32bit code * Supports flat binary file generation * Handles library files (OMF/OBJ) * OMF/OBJ debugging information * Free Cons * Does not support any output file formats other than flat binary and DOS/COM * Confusing to use for beginners * Can't create shared libraries Dirk |
