gwr f9a07c51b8 Allow reading SunOS/4.1.1 object files. Fixes pr/7363 1999-04-12 00:52:44 +00:00
garbled f124765044 More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages.  Many more to
come.

thorpej e278587d62 Move the link.h files for the different shlib formats via repository copy,
and rename them to match the executable format.  Introduce a new link.h
file which automatically picks the correct header based on the target of
the toolchain.

it fixes a problem where it was not possible for some 3rd party
package to have a library with the same name as a library already
in the system, and a lower version number. The highest version
would always be picked. This particular problem shows up with Mozilla,
which has a libutil.so.1.0

pk c682966345 Patch from Chris Demetriou to unmap an object on last dlclose(), which
had not be implemented. It would cause an "adress space leak" and, if
the same object would opened multiple time, unwanted relocations.
Re: Comment from Chris:

"The a.out ld.so has some problems with dlclose.  It doesn't properly
unmap objects which are dlclosed.  That's a known problem (though a
serious one for programs which dlopen then dlclose lots of objects,
because it causes address space exhaustion), but it has a
previously-unknown side-effect.

If a single object is dlopened, then dlclosed, then dlopened _again_,
the relocations will be processed again.  That causes obvious
problems."
