Well, I haven't read the ABI, so I'm certainly no expert. This would suggest that the ABI implies a single operating system so that all the kernal calls will look the same. This makes sense since the ABI is backed by AT&T and they would be pushing for UNIX as that one operating system. I thought that the ABI was just a specification that attempted to ensure that executable code looked consistent when it got to the CPU as an executable, but stopped short of how the executable code was translated from source code. For instance, UNIX might call it an open() in source, but AmigaDOS might call it Open() in source. The ABI wouldn't care as long as it looked the same in the final executable. David – via Whap!
