recursions.

Deal with address offsets. Address lookup is now:
- First convert the address to an offset into the file
- Then convert to an offset into the text segment
- Then add the load address of the text segment (found in the
debug binary)
- Then finally lookup the result in the symbol table.
* elfparser.c (elf_parser_get_text_offset): New function
* elfparser.c (elf_parser_lookup_symbol): Treat addresses as
offsets into the text segment.
* binfile.c (bin_file_new): Store the offset of the text section
of the actual binary (not the debug one)
(bin_file_lookup_symbol): Subtract text_offset before passing
address to elf parser.
* module/sysprof-module.c: Remove include of linux/config.h

* collector.c (unique_dup): Take a string instead of a
Symbol.

make it an opaque structure.

Tue Sep 27 01:33:33 2005 Soeren Sandmann <sandmann@redhat.com>
* process.c (process_lookup_symbol): If the address is 0x01, treat
as kernel, regardless of whether we have a map for that address or
not.
* module/sysprof-module.c (timer_notify): Take a stack trace of
the current process, even when we are in kernel mode. This way we
can assign kernel activity to individual user space stacktraces.
* TODO: updates.
Tue Aug 30 16:57:33 2005 Søren Sandmann <sandmann@redhat.com>
* configure.ac: Complain if we can't find /lib/modules/`uname
-r`/build/Makefile.

kernel.

SEC_LOAD.

function and all references to it.
* binfile.c (bin_file_lookup_symbol): Document that address must
be in file coordinates.
* binfile.c (read_symbols): Remove misguided code that tried to
guess the load address of the file. Instead, do all computations
in "file coordinates". Also fix a memory leak. Add commented out
debug spew.
* binfile.c (separate_debug_file_exists): Fix signedness
Thu Mar 31 19:51:51 2005 Søren Sandmann <sandmann@redhat.com>
* sysprof-module.c (do_generate): Walk all threads, not just all
processes.
