Keyword substitution: kv
Default branch: MAIN

Added DT_GNU_HASH symbol resolver.

gcc 4 fixes

now at least diet-dyn works ;)

remove _dl_fmt_xlong0 as it will always be unused
(functionality was aready implemented...)

  add sigisemptyset, sigandset and sigorset (John K. Hohm)
  minor additions to make gdb 6.3 happy (John K. Hohm)
  ld.so support for gdb (John K. Hohm)
  implement nice(2) via setpriority() if there is no nice syscall

alpha long time no check update (missing symboles)
libdl: minor flag changes

*/__testandset.S: jump to global symbol with local jump
libdl/*: added symbol-types and comment cleanup

fixing the dynamic COPY-relocation bug...

ok, several fxes:
  - gcc-3.x doesn't like multiline-strings (used in the inline assembler)
  - gcc-3.x doesn't have __func__ but ONLY __FUNCTION__
  - dlopen/dlsym fixed for dlopen(0,...)

ok. the new libdl code is now the default.

- so now the new dynamic-linker is working; some more tests and then it's
  the default...
- modified the old one so it still can be used.
- recode the DEBUG code so it can be used in the minimalistic syscall
  enviroment of the libdl.so/dynlinker (only a sub-subset is available)
All in one line:
  libdl.so+dynlinker < 10k on x86 :)

some minor fixes...
added symbol resolver do _dl_main (new dynamic linker)

little changes for new concept of libdl.so

type changes.

ok now the first dynamic linked program (uses libdl.so and libdietc.so) has
loaded a test-library (depends on libdietc.so) correctly and resolves all
used symbols. (with dlopen form libdl.so and not from the dynamic-linker).

changed the diet warpper to generate dynamic-linked programs and shared
objects.
found some non-working functions due to libdl/dietld.so (still debuging).

make dynlinker "interact" with loaded libdl.so... evil evil...

so now dynamic-libc works again and the last missing relocationtype now
works too.

little change. fail if depending lib fails.

fixed relocation type 1 and removed unused variables

and now:
REMOVED the support for textrel...
have read an other spec that says: neede TEXTREL relocation types can't
be present in dynamic libraries... ARG... is there any sane standard ?!

other: minor changes...

added support for shared libraries with relocations in the !! read only !!
text-segment (e.g. libraries compiled without -fPIC)

a little different DEBUG-macro :)
a macro with var-args....

added prototype...

errorhandling in dlopen (_dl_load.c)
other DEBUG macro

so here it is:  the dynamic loader (ld.so replacement)

some changes... now the test-ldso dosen't get a SIGSEGV...
works on i386 ...

changed some stuff yesterday and forgot to commit them...
so here is the dlopen... for first ldso implementation...

noch schnell einchecken.... :)

little changes...

uff.. a little more spec-complient dlopen...
the depending libs are loaded in the correct order...

minor changes (name handling...)

changed some prototypes...

generate more meaningful error messages

minor changes (more debug code ...)

now supporting bulk relocation.... and GOT discovery if non present in the
dynamic section !?!

now there is a "minimal", non-spec complient automatic open of needed libs
(this is really crap ...) this code can't detect loops ....

so a little more dl .... (redefine ELF please...)

arm start-code is now dynamic aware

some minor test-changes in libdl

changed some ...

still all is a TEST

TODO:
dlopen:
	- has to load needed dependent shared objects via itself .....
	- support for all relocations
	- generate "correct" errors for dlerror
	- support for non x86 code
	- rewrite for all this points....

dlerror:
	- meaningful messages ....

dlclose:
	- depends on dlopen

dlsym:
	- depends on dlopen

a little status :)

so here now my experimental code...

IT DOESN'T WORK !!! (working open only with me "special tests")

its here for multiple position-coding :)
