jdolecek 06d16ede1e slighly move the assert() added in last commit, so that it's
actually useful
2000-06-03 06:51:57 +00:00
jdolecek 2a05365bbb _rtld_unref_dag(): needed->obj might be null if the unreffed object has
some unsatisfied references (most often when compiled without necessary
	-Wl,-R), so check for that instead of causing null-dereference;
	this way the code has a chance to cleanup after itself and report
	the error to caller

Thanks to Jason Thorpe for helping fix this!

chs 871e0c1533 switch back to using a file mapping for the initial mapping of a new object.
this allows the kernel to use PMAP_PREFER() to give us better alignment on
platforms that care.

kleink 65b8f3b2eb Change _rtld_dlclose() to unload the object via _rtld_unload_object() rather
than by itself.  Besides being duplicated code the open-coded version
also did not take care of cleaning up after the object's DAG(!).
Fixes PR bin/8905.

itohy 69c745c3d5 Use "addend" for R_68K_GOT32, R_68K_PC32, and R_68K_32 relocations.
I'm not sure whether R_68K_GOT32 relocations appear in shared
objects, though....

Example:
	lea	%pc@(got+0x1234@GOTPC),%a0	| R_68K_GOT32
	bsrl	foo+0x5678			| R_68K_PC32
	lea	bar+0x9abc,%a1			| R_68K_32

crawl before you walk.

thorpej 5c5817ee4a When allocating the entire address space of an object, map an anonymous
region first (using the data/bss protection) covering it, then overlay
the text and data regions at the appropriate offsets within the region,
and then unmap any gap between the text and data.

The previous method of maping the entire address space with the actual
file object itself is incorrect, as it may extend past the end of the
file if the section alignment is large enough.

This bug was the source of the libposix failure on the SPARC and another
similar failure (with libc!) on the Alpha (failure was accompanied by
a "uvn_io: size check fired" message on the console).

kleink 1cc052ce00 Rearrange the shared library search path precedences to LD_LIBRARY_PATH >
runpath > built-in default; this is the behaviour of the SVR4 shared loader,
and gives users the opportunity to override the runpath.  (Addresses a report
on current-users by John Kohl.)
