9108f12f6b move the defines for RTLD_ARCH_SUBDIR into a sub-sub-makefile so we can 
grab these values via reach-over more easily.

8679e33545 if LD32DIR is defined: 
- look in src/compat/lib/libc for libc_pic.
- define RTLD_ARCH_SUBDIR to "i386" or "sparc" for amd64 and sparc64
  builds, respectively
if RTLD_ARCH_SUBDIR is defined, add this path before
RTLD_DEFAULT_LIBRARY_PATH in the default search path.

38bdc8954f Refactor common code to _rtld_relocate_plt_object to i386 and arm so they 
act like the other versions.
In _rtld_bind, if the result is 0, call _rtld_die.
Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase.  Now when
the symbol is resolved, st_value + maprelocbase will equal 0 and the above
check in _rtld_bind will fire and a call to NULL will be avoided.

d3b459e727 abort() if we are trying to use an undefined weak symbol from the plt. Remove 
check from relocate_plt_object() since we cannot return _rtld_sym_zero anymore.
Code from gimpy.

0d33a45b97 handle sym_zero like x86_64; other ports might need this too. 2008-07-22 22:27:07 +00:00

56e895e29f deal specially with sym_zero, returned by a weak symbol that was not found, 
by retrieving it's name instead of printing random garbage.

0c6e4dbbc4 ok, the change from rev 1.33 was unnecessary after all, 
only the second part of the previous revision was needed.
put the logic for the initial icache invalidation of the PLT
back the way it was, but in a way that makes clearer what's going on,
and add some comments explaining it.

 - fix pointer arithmetic in other calls to __syncicache().

38fb01be3a Apply fixes from Charles: 
- Fix how _rtld_relocate_nonplt_self deals with REL32 relocations.

- Change the assert so that it is correct for binutils 2.14 and 2.15.

There are still problems with the libraries generated with binutils 2.15,
but at least ld.elf_so doesn't crash.
