I assume you mean across a set of input files--it's unusual for a single input file to have multiple input sections with the same name. Across input files, it is routine; for example, by default, all ordinary code will be put into the .text section in each input file. > When the linker sees two input sections with the same name are we saying > that it only ever keeps one copy or are we saying that only if it starts > with the special .gnu.linkonce. prefix is just one section kept? Only if it starts with the special .gnu.linkonce. prefix. Otherwise all input sections with the same name are normally combined into an output section with that name. There is a lot of basic information about linkers in my blog entries starting at http://airs.com/blog/archives/38 . Ian
