|
* News for v0.98.3:
|
|
|
|
|
|
|
|
|
|
** Make it possible to link against libunwind-ia64.a only (i.e., without
|
|
|
|
|
requiring libunwind.a as well). This keeps apps which need only
|
|
|
|
|
remote unwinding cleaner, since they logically have no dependency
|
|
|
|
|
on libunwind.a.
|
|
|
|
|
** Dont link against libatomic_ops for now. Due to a packaging bug on
|
|
|
|
|
Debian, linking against this library causes libunwind.so to get
|
|
|
|
|
a dependency on libatomic_ops.so, which is not at all what we want.
|
|
|
|
|
Fortunately, we don't have to link against that library on x86 or
|
|
|
|
|
ia64 since the library is strictly needed only for platforms with
|
|
|
|
|
poor atomic operation support. Once the libatomic_ops package is fixed,
|
|
|
|
|
we can re-enable linking against libatomic_ops.

|
|
* News for v0.98.2:
|
|
|
|
|
|
|
|
|
|
** Fixed bug which caused _UPT_get_dyn_info_list_addr() to sometimes fail
|
|
|
|
|
needlessly. Found by Todd L. Miller.
|
|
|
|
|
|
|
|
|
|
** When using GCC to build libunwind on ia64, libunwind.so had an
|
|
|
|
|
unresolved reference to __divdi3. This is undesirable since it
|
|
|
|
|
creates an implicit dependency on libgcc. This problem has been
|
|
|
|
|
fixed in the 0.98.2 release by explicitly linking against libgcc.a
|
|
|
|
|
when building libunwind.

** Fixed a bug which caused "make install" to install libunwind-common.h.in
|
|
|
|
|
instead of libunwind-common.h.
|
2004-10-15 15:37:27 +02:00
|
|
|
|
** Fixed a bug in the ia64 {sig,}longjmp() which showed on
|
|
|
|
|
SuSE Linux 9 because it's using a newer compiler & the EPC-based system
|
|
|
|
|
call stubs.
|
|
|
|
|
** Fixed incorrect offsets in tests/ia64-test-nat-asm.S.
|
|
|
|
|
Warning: you'll need a GNU assembler dated later than 21-Sep-2004 to
|
|
|
|
|
get this file translated correctly. With an old assembler, "make check"
|
|
|
|
|
will get lots of failures when running Gia64-test-nat or Lia64-test-nat!
|
2004-10-13 16:14:10 +02:00
|
|
|
|
** Convert tests/bt into a full-blown test-case. It's designed to
|
|
|
|
|
trigger a (rarely-encountered) bug in the GNU assembler on ia64.
|
|
|
|
|
The assembler has been fixed and once the libraries (libc etc)
|
|
|
|
|
have been rebuilt, this test will pass.
|
2004-10-15 15:37:27 +02:00
|
|
|
|
** Added test-case tests/run-ptrace-misc which, on ia64, triggers a bug in

current GCC (including v3.4.2) which causes bad unwind info.

* News for v0.97:
|
|
|
|
|
|
|
|
|
|
** unw_get_proc_name() may now be called from signal-handler.
|
|
|
|
|
|
|
|
|
|
** The ptrace-helper routines are now declared in libunwind-ptrace.h.
|
|
|
|
|
Applications which use ptrace-based unwinding should include
|
|
|
|
|
<libunwind-ptrace.h> to get the _UPT_*() routines declared.
|
|
|
|
|
|
|
|
|
|
** libunwind has been split into a "local-only" and a "generic" versions.
|
|
|
|
|
The former is optimized for local unwinding (within a process) and
|
|
|
|
|
is called libunwind.so (shared version) or libunwind.a (archive
|
|
|
|
|
version). The generic version is not limited to unwinding within a
|
|
|
|
|
process and is called libunwind-generic.so (shared version)
|
|
|
|
|
libunwind-generic.a (archive version). Similarly, the ptrace()
|
|
|
|
|
support has been separated out into a convenience library called
|
|
|
|
|
libunwind-ptrace.a. For the most part, backwards-compatibility
|
|
|
|
|
is retained. However, when building an application which uses
|
|
|
|
|
libunwind, it may be necessary to change the linker command-line
|
|
|
|
|
as shown in the table below:
|
|
|
|
|
|
|
|
|
|
Application which does: Before v0.97: With v0.97:
|
|
|
|
|
----------------------- ------------- -----------
|
|
|
|
|
local unwinding only: -lunwind -lunwind
|
|
|
|
|
remote unwinding: -lunwind -lunwind-generic
|
|
|
|
|
cross unwinding: -lunwind-PLAT -lunwind-PLAT
|
|
|
|
|
ptrace-based unwinding: -lunwind -lunwind-ptrace -lunwind-generic
|
|
|
|
|
|
|
|
|
|
The motivation for this splitting is to keep libunwind.so as minimal
|
|
|
|
|
as possible. This library will eventually be loaded by most (if not
|
|
|
|
|
all) executables and hence it is important to ensure that it can
|
|
|
|
|
be loaded as quickly as possible.
|
|
|
|
|
|
|
|
|
|
** unw_getcontext() tuned on IA-64.
|
|
|
|
|
|
|
|
|
|
The unw_getcontext() routine used to be provided by (GNU) libc
|
|
|
|
|
(getcontext()). This caused unnecessary overhead (e.g., an
|
|
|
|
|
unnecessary system-call to sigprocmask()). The new
|
|
|
|
|
unw_getcontext() only does the work really needed for libunwind and
|
|
|
|
|
hence performs much better. However, this change implies that
|
|
|
|
|
programs linked against libunwind v0.97 won't be
|
|
|
|
|
backwards-compatible with earlier versions (there would be an
|
|
|
|
|
unresolved symbol for _Uia64_getcontext()).
|
|
|
|
|
|
|
|
|
|
** Fix NaT-bit handling on IA-64.
|
|
|
|
|
|
|
|
|
|
New test-cases have been added to test the handling of the NaT bit
|
|
|
|
|
(and floating-point NaT values) and all discovered/known bugs have
|
|
|
|
|
been fixed.
|
|
|
|
|
|
|
|
|
|
** Initial DWARF-based unwinder for x86.
|
|
|
|
|
|
|
|
|
|
There is a beginning for a DWARF-based unwinder for x86. Work for
|
|
|
|
|
x86-64-support based on this DWARF unwinder is currently underway
|
|
|
|
|
at IBM and it is expected that this support will be merged into the
|
|
|
|
|
official tree soon.
