* check if USE_TLS is defined before useHans-Christian Egtvedt2009-12-171-10/+10
| | | | | | | | | | | This patch will convert all the #ifdef USE_TLS and #if USE_TLS to #if defined(USE_TLS) && USE_TLS. By checking if the USE_TLS is defined before checking its value will result in correct behavior for architectures not defining this config symbol.

* ldso: clean up breakage in tls mergeMike Frysinger2009-10-151-25/+14
| | | | | | | | | | The TLS merge 534661b91c9849 introduced multiple style problems as well as random breakage: - missing _dl_free - incomplete parametrization of _dl_lookup_hash - restore FDPIC handling in _dl_lookup_hash Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin FD-PIC patch 6/6.Bernd Schmidt2007-12-041-1/+3
| | | | | | | 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.

* Blackfin FD-PIC patch 3/6.Bernd Schmidt2007-12-031-1/+1
| | | | | | | | | | | | | | | 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.
* Blackfin FD-PIC patch 2/6.Bernd Schmidt2007-12-031-3/+24
| | | | | | Add the necessary changes in ld.so and libdl to deal with targets that prepend an underscore to symbol names.
* Blackfin FD-PIC patch 1/6.Bernd Schmidt2007-12-031-1/+14
| | | | | | | Add a new function _dl_free. In _dl_malloc, ensure we always get back a full page from mmap. Reset _dl_malloc_function and _dl_free_function when libdl is initialized.
* Bernd Schmidt writes:Joakim Tjernlund2007-03-311-4/+1
| | | | | | | | | | Currently a static libdl.a doesn't run all the constructors or destructors of the libraries it loads. I can't see a good reason for that, and it does cause aborts in the destructors it does run for things like libgcc.so on the Blackfin. Fixed with the patch below - untested in mainline, but the equivalent has been in our Blackfin tree for a while now.
* Carmelo Amoroso writes:Joakim Tjernlund2007-03-131-0/+33
| | | | | | | | | Hi All, the attached patch completes my previous patch on statically linked application calling dlopen enabling the support for LD_DEBUG. Further it fixes the missing initialization of the _dl_library_path variable. This patch has been fully tested with the uClibc-nptl branch (sh4).
