Update TODO list a bit

Only print debug stuff when asked

Fixup a couple of warnings

Avoid multiple passes to perform mips GOT relocations, and do
the whole lot in a single pass.
-Erik

Fixes from gentoo.

Let ldso find libc's malloc function and set _dl_malloc_function.
This removes some crap in libdl.c(and future libs which needs
to access ldso functions).
What do you think?

Added test for RTLD_GLOBAL flag in _dl_find_hash().
Fixed a bug in libdl.c where the RTLD_GLOBAL was assigned
wronly.

Relocations of the application's global GOT entries were not being run, and
only the global GOT entry relocations for the loaded shared libs were being
handled. This made applications segfault when using un-fixedup symbols. After
many hours debugging to track down the problem, this patch makes the mips port
happy again.

"I fixed the _dl_parse_copy_information in the same way than for the
powerpc and it works fine for me.
You may luck at the patch for the powerpc/elfinterp.c, where I change
the paramter of a dl_dprintf statement. Now we use the same
parameters than for the relocation copy."

Arch mantainers, please do the same.
When all arches has been fixed, we can remove of _dl_parse_copy_information,
it is just a waste of CPU cycles.

find attached a smaller version ... perhaps adding a fprintf to stderr before
calling abort would be nice like in the glibc patch, but whatever

glibc has since adopted a similar fix for their malloc (third hunk, line 1970)

i sent this earlier but perhaps people missed it the first time around :)
http://www.uclibc.org/lists/uclibc/2004-August/009544.html

basically if you try to #include <sys/ucontext.h> on arm it'll fail because
ucontext.h utilizes typedefs found in bits/sigcontext.h ... i386 already has
this fix in uClibc

find attached a trivial patch to fix this

Hi Manuel & Erik

I think I know why MIPS is broken. _dl_perform_mips_global_got_relocations() is
broken. It will due to my latest changes reloctate ldso. This
function needs to die and its job should be done inside _dl_parse_relocation_information().
It is mostly a copy and paste job,

Also PERFORM_BOOTSTRAP_GOT and PERFORM_BOOTSTRAP_RELOCATION should be fixed, they
use symbols which aren't passed as arguments.

Patch by Carl SHAW <carl.shaw@st.com>...

Below is a patch to make the pread and pwrite calls work on the SH
architecture. I've only tested this on the SH4 with a 2.4.24 kernel - a
fairly recent kernel is required as the problem is partially fixed in
the kernel itself. For more information (in relation to glibc, but the
problem is the same) see the thread at

http://sourceforge.net/mailarchive/message.php?msg_id=2375908

Someone should really test this on the SH2/3...

Patch from Stefan Allius:
Remove unused function parameter in ldso.
Remove echo option '-e' since it is not supported on Solaris.

Hopefully fix Laszlo and Jacobs dlopen problem.

Note a security item for the next release

Make the stub profiling stuff work

The "Delete current profiling code because it is complete crap"
TODO item is now done.

Attempt to support 'gcc -finstrument-functions', which seems much
more sane than 'gcc -pg' and seems much easier to support.
-Erik

Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both a
size and performance penalty to profiling applications this way, as well as
Heisenberg effects, where the act of measuring changes what is measured.
There are better tools for doing profiling, such as OProfile, that do not
require gcc to instrument the application code.
-Erik

Enable only for architectures where __NR_madvise is defined
-Erik

Never directly include kernel sources

'pagesize' was local to dl-startup.c. In ldso.c we need
to use '_dl_pagesize'
-Erik

Fix dependencies.

Accunt for ELF_MACHINE_PLTREL_OVERLAP when relocating ldso.

Remove poor man's malloc. Not needed anymore.

Move "debug_addr" ptr from dl-startup.c to ldso.c

Move the app specific stuff from dl-startup.c to ldso.c.

Oops, forgot to remove unused variable.

This is now done in ldso.c
