* Partial commit of a patch from Alexandre Oliva:Eric Andersen2004-12-111-0/+8
| | | | | | | | | | Here's an updated version of the patch I posted about a month ago. It leaves -nostdinc alone, and uses -print-file-name=include instead of -print-search-dirs to figure out where GCC's internal headers are. Please let me know whether there are any portions of this patch you'd like me to break into smaller pieces, to rework, or to give up trying to get into uClibc :-) Thanks,
* Add RTLD_LOCAL support for dlopened libs. Reported byJoakim Tjernlund2004-11-101-2/+2
| | | | | | | Andrew de Quincey, who has been most helpful getting this sorted out, thanks. Thanks also to Peter Mazinger who did alot of testing. Removed all traces of dl_parse_copy_information() since it is no longer used.
* - Remove dynamic_size from struct elf_resolve.Joakim Tjernlund2004-11-022-9/+51
| | | | | | | | | | - Replace all open coded dynamic handling with a function. Reduces size. - Fold special MIPS dynamic code into the dynamic_info item. - Add RELRO support. - Support linking with "-z now". - prepare for DT_RELACOUNT/DT_RELCOUNT optimization. - Add -z now to ld.so linking, this is what ld.so does anyway so let the linker know that.

| | | | | | | | | 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.
* Remove usage of _dl_parse_copy_information() from generic code.Joakim Tjernlund2004-10-072-7/+4
| | | | | | Remove definition of _dl_parse_copy_information() for powerpc. Remaining archs can do the same. Make debugging output of "relocation processing: xxx" a bit more sane.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hello, I managed to get ldso (and thus shared linking to uClibc) to work on sparc (actually sparc64 kernel with 32-bit userspace), at least on simple "hello world" program (more complex ones not tested). Some notes on attached patch (against 0.9.26, would require some work to apply on current CVS - but I tested 0.9.26, not CVS): - ELF magic cannot be examined by _dl_strncmp so early, probably because of string constant, like on ppc/mips/sh (note that early SEND_STDERR still crashes when trying to do _dl_strlen - I suppose that string constants require relocation; but adding load_addr didn't help, just ELF header was displayed instead of crash) - mmap() is syscall6 like on ppc/mips/sh, not old i386 mmap() - for generic sparc (i.e. not sparcv8/sparcv9) gcc produces .udiv/.urem calls for unsigned integer / and % operators - so these operations must be avoided. I copied do_rem definition from arm header. But / and % are used also in _dl_simple_ltoa() and _dl_simple_ltoahex(); in ltoahex gcc optimizes it to shifts (but I think it's safer to use shifts explicitly, not rely on optimization...). I changed % in ltoa to do_rem, but as there was no do_div definition, I changed all "%d" specifiers to "%x" to avoid crashes (this changes wouldn't be needed if _dl_simple_ltoa() were fixed to not use division on sparc). - "#define SOLARIS_COMPATIBLE" in ld_sysdep.h broke ldso on Linux because of redefining _dl_linux_resolve only in some places (it was still referenced in INIT_GOT before redefinition). So _dl_linux_resolve redefinition should be moved before INIT_GOT definition or removed. - sparc64 kernel requires mmap() addresses to be aligned to 8192, not 4096, otherwise mmap() call failed - reloc_entry must be shifted by 10, not 12 (I found similar operation in glibc sources) Aside of sparc-specific fixes: - I moved some _dl_dprintf()s inside if(_dl_debug_*) conditions (to avoid debugging messages when LD_DEBUG is not defined) - it seems that there was possible off-by-one in ltoa and ltoahex? they are called with char[22] as 1st argument, and then '\0' is stored in local[22] (_before_ p decrementation)... or am I missing something? If not, fix is included in patch.

| | | | | | | | | | | | | | | | | | Hi it is me again. This is the latest ldso patch. the NEW weak symbol handling works now with a little special handling in _dl_find_hash(). You get to chose if you want the new or old handling :) There was 2 missing _dl_check_if_named_library_is_loaded() calls in _dlopen(). I then disabled the _dl_check_if_named_library_is_loaded() in dl-elf.c since it is rendundant. Question, why does some _dl_linux_resolver(), like i386, have 2 calls to _dl_find_hash()? I think that is wrong, isn't it? I really hope you can check this out soon ...
