The last reference I can see to this issue is a Feb 2002 post to this list:
"niv twig" <[EMAIL PROTECTED]> writes:The gnu ld linker has no capability for incremental linking which is found in almost all other commercial linkers: Microsoft visual C++ linker, Sun ild (incremental ld) linker for the Forte IDE, HP also has an incremental linker.
Incremental linking will be added to the GNU linker when somebody volunteers to write it or to pay for it.
Perhaps you could be that volunteer?

Did any work ever get done on this?
The current gnu linker has an "incremental" flag, but it's documented as be identical to "-r" (relocatable output). That is, it does a partial link - producing effectively a larger object file that can be used as input to future links, but which is not executable. The "-Ur" option seems to create a relocatable executable with C++ link-time magic performed, for environments where the whole executable needs to relocated (VxWorks perhaps?).
Anyone have any information about what work may have been done on a true incremental link mode?
Anyone have any comments, wish lists, or warnings about how to go about potentially implementing it?
