I don't think you want to add 16 bit support even if someone pays you to do it. The real issue is the binary format. For object modules, the format is something called OMF. The executable program format is something else. I would guess that adding OMF to gas (and all that bfd stuff) will take man-years. From: Ian Lance Taylor <ian@cygnus.com> Date: Thu, 25 Aug 94 00:16:31 EDT I know as little as possible about the i386, and I certainly know nothing about the differences between 16 and 32 bit mode. Can anybody on this list help? I'm sure that nobody at Cygnus plans to add support for 16 bit mode, unless, of course, we find somebody to pay for it.

I found your E-mail address in the 2.3 version of GNU GAS. Please excuse me for bothering you. I would like to ask for your opinion on some modifications I would like to make to GAS. I am working on a major project which requires a cross-platform, x86 assembler, for both 16 and 32 bit code. That is where my problem lies, I know GAS does not currently support 16 bit code, but how much effort do you think it will take to add it? Is this being planned for GAS? If so, when do you think it will be done? If it looks like I'll need to add 16-bit support myself, please send me a list of things I'll need to check. I think I can figure it out from the 2.3 distribution, but I'd like to know about any special problems that are not immediately obvious. Thank you for your time. ----------------------------------------------------------------------------- Thomas Harmon "He's no fun, he fell right over." harmon@feenix.metronet.com -- Four or Five Crazy Guys -----------------------------------------------------------------------------
