2012-06-15dl-defs.h: include dl-sysdep.h before fallbacks.Peter S. Mazinger
dl-sysdep.h has to come before the fallbacks in dl-defs.h, else the wrong macros are used. While there adapt the guard to the file name. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-04-08ldso: fix fdpic support broken from prelink patchFilippo Arcidiacono
The fdpic support has been broken since the prelink support was added, because it didn't take into account DL_LOADADDR_TYPE could be a different type of ElfW(Addr). Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-05-10libdl: fix local symbol's address handling in dladdrFilippo Arcidiacono
Fix dladdr to correctly handle local function's address so backtrace_symbols print only the function address for these function, instead of showing the name of nearest one. Indeed the dladdr walk through the hash table to find the nearest symbol, that doesn't contain local symbols.

2011-03-05Add support for DSBT ELF to ld.soMark Salter
This adds support for DSBT ELF to ld.so. This uses loadmaps like FD-PIC. Some code is added in ld.so to initialize the DSBT tables, and there's also a new target macro FINISH_BOOTSTRAP_RELOC.

2010-09-17ldso: Rework global scope handling and symbol lookup mechanismFilippo Arcidiacono
Global symbol scope is implemented as a linked list of local scope, that dynamically grows and shrinks when dlopen/ dlclose are called. Each local scope is implemented as an array of pointer to struct elf_resolve. This will help to detect conflict when LD_TRACE_PRELINKING option will be implemented.

2007-12-04Blackfin FD-PIC patch 6/6.Bernd Schmidt
These are mostly the changes necessary to deal with loading the libraries into memory. A couple new target macros are defined for this purpose, and the code in dl-elf.c is modified to deal with nommu systems.
2007-12-03Blackfin FD-PIC patches 5/6.Bernd Schmidt
A couple more target macros for ld.so to deal with FD-PIC support. We need special code to compute the initial got and dpnt, and we need to pass extra arguments to _dl_get_ready_to_run.
2007-12-03Blackfin FD-PIC patch 3/6.Bernd Schmidt
Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch. _dl_find_hash is now a wrapper function around it; unlike on the NPTL branch, it retains the old interface so that not all callers need to be changed. _dl_lookup_hash can optionally give its caller a pointer to the module where the symbol was found. Introduce ELF_RTYPE_CLASS_DLSYM for lookups from libdl. Spelling fixes in the Blackfin port, since Alex Oliva's original version of these patches used _dl_find_hash_mod as the name of the function rather than _dl_lookup_hash.
2007-12-03Blackfin FD-PIC patch 2/6.Bernd Schmidt
Add the necessary changes in ld.so and libdl to deal with targets that prepend an underscore to symbol names.

From Atsushi Nemoto.
2006-11-17Bernd Schmidt writes:Mike Frysinger
This reintroduces a mechanism identical to the DL_BOOT macro present in older versions of uClibc. On Blackfin and FRV, we want to pass more than one argument to _dl_start. We also want to do something special before returning, so delete the warning when the START macro is defined.

2004-10-12Mark Rakes writes:Joakim Tjernlund
without LDSO_CACHE_SUPPORT turned on, LDSO_CONF and LDSO_CACHE are not defined anywhere, but still used by ldconfig.c This patch allows ldconfig to build again, although there may be a cleaner way to fix this???? Applied with minor modification.

dl-cache.h and make use of it. Also disables the lib-path-redundancy check for the case the cache is not used. Makes use of _PRELOAD_FILE_SUPPORT. From Peter Mazinger.
