2003-08-21Be sure to remove the old ldso.h, since it will screw thingsEric Andersen
up badly if still present...
2003-08-19Phase one of my evil plan to clean up ld.so...Eric Andersen
2002-11-20Patch from Stefan Allius:Eric Andersen
- 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
2002-11-08Patch from Stefan Allius for libgcc multilib supportEric Andersen
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. ---------------------------------

Move all configuration options into the new config system. -Erik

2002-10-31Ok, this commit is _huge_ and its gonna change the world. I'veEric Andersen
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
2002-09-16Updated for the CRIS port.Tobias Anderberg
2002-08-09Link ldso vs libgcc.a and eliminate baggage caused byEric Andersen
not previously linking vs libgcc -Erik
2002-08-08Patch from Stefan Allius and Edie C. Dost to add SuperHEric Andersen
shared library support. This also adds some cleaner error handling, which I (Erik) then ported over to x86 and arm. In addition Stefan added the following fixes: - in hash.c was the lvalue handling of global library functions wrong. To fix this I had to change the prototype of _dl_find_hash. (==> TIS and ELF spec. Vers. 1.2) - in ldso.c was the order of the .init sections calls wrong. Before we call the initialization code of a library we have to check that all dependend libraries are already initialized. This can easily made by calling it in the revers loading order. For this I added a previous pointer chain. - in ldso.c the ELF magics wasn't checked fo PPC, MIPS and SH architecture
2002-05-28Fixup and unifiy version numbering. Automate versioning updates.Eric Andersen
Propagate fixes across makefiles. -Erik
2002-03-19Add new debug target (disabled by default) so that when debugEric Andersen
is on we now default to resolving symbols permanently.. -Erik
2002-03-17Enable trace support by default, since it only costs 300 bytesEric Andersen
anyways, and people seem to expect it. -Erik
2002-03-08Seperate out the symbol resolution debugging, so it doesn't clutterEric Andersen
things up when we don't care about symbol resolution problems. Make the lib loader always look first in the directory where the shared lib loader was found. -Erik
2002-02-17A ton of cleanups. Eliminate some useless code. Much betterEric Andersen
debugging code now. -Erik
2002-01-29Go back to using ld, now that I've found the real problem...Eric Andersen
2002-01-23Fixup build a bit. Be sneaky and include everything intoEric Andersen
a single .c file, making stuff be even smaller.
2002-01-16Tell ld explicitly when stuff is supposed to by dynamically linkedEric Andersen
-Erik
2002-01-11Oops. We lost -FPIC in the shuffle...Eric Andersen
-Erik
2002-01-11Rework naming for shared lib loader to avoid potentialEric Andersen
nameing conflicts with std header files. -Erik
2002-01-01Change all 'cd <foo>; bar' constructs to 'cd <foo> && bar' forEric Andersen
proper error checking -Erik
2001-12-19Update my email address. I am no longer andersen@lineo.comEric Andersen
2001-08-08This syncs things up with my local tree. Mainly changes installerEric Andersen
issues, and syns things (as far as I am willing) with Dave Schleef's tree. We may need to go another round or so, but we do seem to be converging...
2001-07-17Turn off USE_CACHE by default (so ldconfig, by default, isn'tEric Andersen
needed). Fix a stupid typo in dlib.c where I had several weak symbols set up backwards, breaking libdl (dlopen and friends), -Erik
2001-07-17Oops. USE_CACHE was disabled and didn't compile when enabledEric Andersen
since I'd forgotten a one liner... -Erik
2001-07-17Forgot this...Eric Andersen
2001-07-13This takes about 6k off the size of the x86 shared lib loader...Eric Andersen
-Erik
2001-07-12This commit merges David Schleef's updates to the build system, which aEric Andersen
few tiny fixups here and there from me. Seems to work just fine and will hopefully be a bit better behaved. -Erik
2001-07-03Allow the shared lib loader to fallback on the builddir if everythingEric Andersen
else fails. Let <arch>-uclibc-gcc --uclibc-use-build-dir set the shared lib loader to the one in the builddir's path. -Erik
2001-06-15Now that our compiler wrapper is up to it, we can now use TARGET_CCEric Andersen
to compile ldso, simplifying the process of passing in special CFLAGS and such (and simplifying the build in general since we no longer need to go directly to LD to link things). -Erik
2001-06-14Yet more ldso cleanups. Be more discriminating about when using inlinesEric Andersen
and when using real functions. Make things be more portable by providing a default C routine to locate the got. -Erik
2001-05-12Ok, this should finish off my massive ro-organization. The sourceEric Andersen
tree is less messy now (which helps), all libraries are placed into uClibc/lib when compiling, all libraries now use a consistant mechanism for being built, all libraries use a consistant naming scheme where the lib name includes the uClibc version number, which makes ldconfig happy and willing to work with us. -Erik
2001-05-10Fix up naming of ld.so so every uses the same define. The top levelEric Andersen
was using one name and the ld.so-1 dir was using another (they happened to be the same). Fix that. -Erik
2001-05-07Put in but leave commented the DL_DEBUG defineEric Andersen
2001-04-27Yet another large update to ld.so. In this iteration I finally gotEric Andersen
the C based syscalls working, which greatly simplifies what it takes to get new architectures running. -Erik
2001-04-26oops again! I forgot to pull in the arch specific stuff, and forgotEric Andersen
to update those makefiles. -Erik
2001-04-26Be more careful about not hard coding names.Eric Andersen
2001-04-25Move libdl and udate build method a bitEric Andersen
-Erik
2001-04-23Ok, seems this _must_ be compiled as PIC code.Eric Andersen
-Erik
2001-04-23Initial checkin for ld.so. This is a combination of effort from Manuel NovoaEric Andersen
III and me. I've been working on stripping out arch dependant stuff and replacing it with generic stuff whenever possible. -Erik
