| | | | | | | | | | | | | | | | | | | | This patch adds code to uClibc to support a new ABI designed for the FR-V architecture, that enables text segments of executables and shared libraries to be shared by multiple processes on an OS such as uClinux, that can run on FR-V processors without an MMU. Patches for binutils and GCC have just been posted in the corresponding mailing lists. The binutils patch was approved, but there's one additional patch pending review, that I posted this week. An updated GCC patch will be posted to gcc-patches@gcc.gnu.org as soon as I complete testing (I used a known-good compiler to test the uClibc patch below). Since the existing dynamic loader code didn't support independent relocation of segments, it required changes that were somewhat extensive. I've added a number of new machine-specific macros to try to keep the platform and ABI-specific details outside the generic code. I hope this is not a problem.

| | | | | | | | | | | | | | | | | | 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 ...

| | | | | | | | | | | | | | | | | | Hello, the attached patch fixes ldso compilation on sparc-linux (at least with sparc32 userland). It was made against uClibc 0.9.21, but it's still OK with 0.9.26. There were three problems: - missing __NR_getpid definition - conflicting prototypes in elfinterp.c - syntax error (missing semicolon) in ldso.c With this patch shared libraries and ldso can be built on sparc. It contains also ldso.c syntax fix for m68k - there was the same mistake two lines earlier; but I didn't test build on m68k.
* Revert to scope as used by original code for now, just in case.Eric Andersen2004-01-311-2/+4
| | | | | I still don't have a good handle on why and when the different scope values should be used.

For all relocs but COPY you can use scope instead of scope->dyn->symbol_scope and it is much faster to do that. Search for "Funny" in the patch to see what I mean. Probably I probably broke something, please let me know if it works for you too. I think I am done with ldso now. Has been fun and I hope to actually use uClibc/busybox soon in a project. Ohh, there is one thing left, double sized PLT entries, but maybe these aren't needed in uClibc? Sweet dreams Jocke
