Subject: [patch] [i386] Fix {,un}prelinked libraries for attach/core-load
Hi,
please see comments in the patch. The adjusted testcase FAILs on i386.
"Prelink", March 4, 2004 - by Jakub Jelinek:
http://people.redhat.com/jakub/prelink.pdf
primarily section 7 - REL to RELA conversion
An example of unprelinked -> prelinked library change:

So far GDB expected all such displacements will be always PAGE_SIZE aligned.
This applies for example for re-prelinking of an already prelinked file.
But it does not apply for prelinking of an unprelinked file or unprelinking of
a prelinked file, there can be arbitrary displacement.
It affects i386 (=i686, prelink doc reports also ARM and MIPS) which uses REL.
x86_64 always uses RELA, therefore I have not noticed it so far. i386 still
has to be supported.
This affects both attachment to a PID and core file loads.
This applies in real world if you transfer a core file between hosts and try to
backtrace them, libraries of both hosts may differ whether they are / are not
prelinked.
I could implement some (displacement-forgiving and prelink-modifications
forgiving) comparison of both DYNAMIC segments found. But I do not think it is
useful, if the DYNAMIC address from linkmap vs. bfd do not match it is still a
better chance to try a displacement to make them match. Keeping the file
relocation cannot work anyway when the DYNAMIC address is verified as wrong.
No regressions on {x86_64,x86_64-m32,i686}-fedora15-linux-gnu.
Mostly do you agree the DYNAMIC content does not have to be verifed?
Do you have any comments on the in-code long comments?
Thanks,
Jan

Fix libraries displacement if they change whether they were prelinked.
* solib-svr4.c (LM_ADDR_CHECK): Set L_ADDR even if the DYNAMIC pointer
does not match. Comment why.
