Tommi Rantala 21ad2c19ea Implement _UCD_access_reg() for ARM 
Implement the Linux version of _UCD_access_reg() for ARM. We can
sidestep the register number remapping, as the libunwind register
numbers match one-to-one to the ELF core file register numbers.

Tommi Rantala 7e5cab6dac Add missing newline to debug message in _UCD_access_reg_linux.c 2012-08-21 23:04:07 +03:00
Tommi Rantala e61c6f69c3 Fix function name duplication in Debug() output 
Fix function name duplication in Debug() output that was caused by
manually prepending the debug message with the function name.

Tommi Rantala 2d750952a5 Use constants for ELF magic bytes in _UCD_create.c 2012-08-21 22:30:47 +03:00
Tommi Rantala 5d36914c9b IA64: use tdep_find_unwind_table() in coredump lib 
Fixup commit d93d96ad83 ("Fix compilation
on IA64"), and replace the dwarf_find_unwind_table() call with
tdep_find_unwind_table().

Fixes linkage error on IA64:
../src/.libs/libunwind-coredump.so: undefined reference to `dwarf_find_unwind_table'

Arun Sharma bc056ffc9f coredump: update license to be the same as rest of libunwind 
Per Denys Vlasenko <dvlasenk@redhat.com>:

Sure. It's a trivial file, I don't mind if you use
whatever license you like on it :)

Alexander Larsson edcc521a0e Add helper macros for pointer arithmetics 
ALIGN lets you align pointers and STRUCT_MEMBER lets you get
structure members at a specific offset.

These are useful in general, and will be needed for the coredump notes
cleanup work.

Alexander Larsson b1393b7e63 Clean up the elf notes handling in the coredump code 
We centralize the elf notes handling code in some macros, thus
simplifying the loops over the notes and avoiding code duplication.

Alexander Larsson 0c0ea23cf2 Add support for multiple threads in core files 
_UCD_select_thread() lets you select the active thread from
the core file and _UCD_get_num_threads() tells you how many there are.

Alexander Larsson d627481783 Break out the ifdefs for the UCD_info.prstatus type 
This cleans up the code a bit and makes it easier to refer to
the prstatus type in other places.

Alexander Larsson b9ff650a22 Add _UCD_get_pid and _UCD_get_cursig 
These let you get the pid and the current signal from the coredump.

This isn't strictly unwind related, but these are trivial to implement
as we have the info, and you almost always want these when you're
printing a backtrace from a core file.

Alexander Larsson adbeb79155 Fix build with --enable-debug

per-OS coredump register reader.
