* Looks like this is in fact needed to properly debug dynamicallyEric Andersen2002-12-041-0/+8

* Ok... here's the summary:Manuel Novoa III2002-11-221-1/+1
| | | | | | | | | | | | | | Hopefully locale support will build when cross compiling now. Collation is still not supported, but that's what I'm currently working on. In the next couple of days, I'll probably put up a couple of files for download that will save people the trouble of generating all the glibc locales. Added *wprintf functions, although they currently don't support floating point. That will be fixed when I rewrite _dtostr... or possibly before. Added the wcsto{inttype} functions. Added iconv() and a mini iconv utility. The require locale support and only provide for conversions involving the various unicode encodings { UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built with the locale data, and the internal WCHAR_T.

* Patch from Stefan Allius:Eric Andersen2002-11-205-10/+17
| | | | | | | | | - Invert all FORCE_SHAREABLE_TEXT_SEGMENTS checks. - Define FORCE_SHAREABLE_TEXT_SEGMENTS in the Makefile, so it can be configured by the config system. - linuxelf.h inspects that we don't combine FORCE_SHAREABLE_TEXT_SEGMENTS and SVR4_BUGCOMPAT - Add a new config option for FORCE_SHAREABLE_TEXT_SEGMENTS
* Per suggestion from Stefan Allius, change DO_MPROTECT_HACKS toEric Andersen2002-11-193-6/+6
| | | | the more clear FORCE_SHAREABLE_TEXT_SEGMENTS.

| | | | | | | | | | | | | | | | | | I fixed two little bugs in ldso.c: - For LDD support we test the old environment variable LD_TRACE_LOADED_OBJECTS. - Before we init the GOT table of the dynamic loader we have to check, if we have a DT_PLTGOT entry. If DT_PLTGOT was zero we patch somthing in the header of the dynamic loader. This was the cause, why we have to enable the DO_MPROTECT_HACKS option for all targets, to avoid segment faults. In readelflib1.c I added a warning, if we try to load a shared library, which wasn't compiled with -fPIC or -fpic. So if we disable the DO_MPROTECT_HACKS option we are sure, that we don't waste memory by shared libraries which aren't able to share their text segment. I think this is a helpful option on little embedded systems.
* For now, revert Ronald Wahl's change to dlopen. We need toEric Andersen2002-11-152-2/+2
| | | | | look into what is breaking dlclose() further... -Erik
* Ronald Wahl writes:Eric Andersen2002-11-152-0/+2
| | | | | | I noticed that dlclose() does not work since libraries loaded with dlopen are not marked as "loaded_file". This breaks apache with dynamic modules. I append a small fix against uClibc-0.9.16.

* A powerpc patch from Ronald Wahl:Eric Andersen2002-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ok, now i got it after a day of work. I have had a look into glibc and found the following: sysdeps/powerpc/dl-machine.c: ... case R_PPC_JMP_SLOT: /* It used to be that elf_machine_fixup_plt was used here, but that doesn't work when ld.so relocates itself for the second time. On the bright side, there's no need to worry about thread-safety here. */ { Elf32_Sword delta = finaladdr - (Elf32_Word) reloc_addr; ... The comment made me suspicious. The same position in uClibc looks like this: ldso/ldso/powerpc/elfinterp.c: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = (unsigned long)_dl_linux_resolve; int delta = targ_addr - (unsigned long)reloc_addr; ... When I change it to the following it works: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = *reloc_addr; int delta = targ_addr - (unsigned long)reloc_addr; ... I hope it will not break anything. Can anyone review this change and commit it into CVS? thanks, ron
* Patch from Stefan Allius for libgcc multilib supportEric Andersen2002-11-081-1/+1
| | | | | | | | | | | | | | | | | | this is the last patch, we need to make the support of multitarget libgcc complete. --------------------------------- In ldso/ldso/Makefile I added the CPU_LDFLAGS-y to the LDFLAGS --------------------------------- In libc/Makefile I set the LDFLAGS for the script get-needed-objects.sh with CPU_LDFLAGS-y --------------------------------- In extra/scripts/get-needed-object.sh we now use the LIBGCC from Rules.mak and call LD with LDFLAGS (==CPU_LDFLAGS-y). Addtionally I grep the NM output, to fix the unresolved external __GLOBAL_OFFSET_TABLE__ on SuperH targets. ---------------------------------

* Ok, this commit is _huge_ and its gonna change the world. I'veEric Andersen2002-10-312-4/+2
| | | | | | | | | | | | | | | been working on a new config system on and off for about 6 months now, but I've never been fully satisfied. Well, I'm finally am happy with the new config system, so here it is. This completely removes the old uClibc configuration system, and replaces it with an entirely new system based on LinuxKernelConf, from http://www.xs4all.nl/~zippel/lc/ As it turns out, Linus has just merged LinuxKernelConf into Linux 2.5.45, so it looks like I made the right choice. I have thus far updated only x86. I'll be updating the other architectures shortly. -Erik

* This commit contains a patch from Stefan Allius <allius@atecom.com> to changeEric Andersen2002-10-0111-75/+111
| | | | | | | how uClibc handles _init and _fini, allowing shared lib constructors and destructors to initialize things in the correct sequence. Stefan ported the SH architecture. I then ported x86, arm, and mips. x86 and arm are working fine, but I don't think I quite got things correct for mips.
