being modified.

22fbc67ed0 Don't resolve symbols to PLT entries on the VAX. It just causes a lot of 
overhead.

1200e7d3fe More PPC64 changes. 
Nothing to do for lazy bindings.
Record DT_PPC64_GLINK and make _rtld_bind return it.
When resolving a JMP_SLOT, copy the source function descriptor into the PLTGOT

5fbbc292aa CID 1132773: Fix file descriptor leak 2013-11-27 18:01:33 +00:00

03ee7fc3bc If dlopen of the dynamic linker is requested, e.g. by rump in 
rumpuser_dl_bootstrap, then return &_rtld_objself as the handle and do
not create a duplicate mapping.

The handle is mostly useless as _rtld_objself doesn't appear on
_rtld_objlist.

This fixes a problem on earm platforms where ld.elf_so (currently) has
an init_array section.  Calling this caused binaries to segv.

abea8b316b The R_SPARC_L44 relocation type is documented to be truncating and 
calculated as "(S + A) & 0xfff" - so while it (usually) sets a "imm13" field
in the opcode, only 12 bits of the calculated value can be used.

a6c6eb019c Some architectures can't create unwind tables without the frame pointer, 
so don't use -fomit-frame-pointer on those.

a3fedff4d1 Fixed handling of DT_SONAME: 
- add function to add name aliases for shared libraries loaded
	  XXX[1]: we don't add a name during load time, only when DT_SONAME
	  is present.
	- search already loaded objects in load_by_name for an already
	  loaded object that matches our name and return it.
	- add missing initialization and cleanup for obj->names
	  XXX[2]: should we make them SIMPLEQ?
	- Add XXX in rtld.c about getting the name of an object.

NB: This makes the jdk work again without resorting to a hack of putting
    the build path of libjvm.so into the run path (which is a security
    problem).
XXX: Pullup-6?
