After splitting up alpha/rtld_machine.c into 2 or mor parts, any combination where the 1st and the 3rd function (_dl_md_reloc and _dl_md_reloc_got) were not in the same source allowed the split-up sources to be compiled without breaking ld.so. Looking with my untrained eye at the generated assembly or the dissasembled objects did not give me any clue as to why this was happening. I split _dl_md_reloc_got() out into a separate file and compared the generated assembly language. There are no differences. I also disassembled the object files, no code differences. I did similar and saw no noticable differences either, other than the address the function was on that is.. I wonder if ld(1) could be to blame. If so, why would it do that? It should behave the same as when compiled with gcc3 (theoretically at least).. I can think of some theories: - does compiling ld with gcc4 introduce/expose a bug in ld? (I used a gcc4 compiled ld back then) - does the gcc4 compiled rtld_machine.c cause an other codepath than the gcc3 compiled version in ld on which there has always been a bug?

Please don't undo it. Actually, return with braces is old KNF, just like KR function declarations are. Developer taste change over time, and style(9) no longer says anything about return statements style. While there is no explicit mention of this, there is one example of a return with a return value and that does use the braces so I can understand where people might get the impression it is needed.
