 *** Stack backtraces
 
+GDB's code base is being been updated to use a new backtrace
+mechanism.  This mechanism makes possible the support of new features
+such DWARF 2 Call Frame Information (which in turn makes possible
+backtraces through optimized code).
+
+Since this code is new, it is known to still have a few problems:
+
 gdb/1505: [regression] gdb prints a bad backtrace for a thread
 
-When backtracing a thread, gdb doesn't stop until it hits garbage.
-This is sensitive to the operating system and thread library.
+When backtracing a thread, gdb does not stop when it reaches the outer
+most frame, instead continuing until it hits garbage.  This is
+sensitive to the operating system and thread library.

-GDB's SPARC, MIPS and PowerPC targets, in 6.0, have not been updated
-to use the new frame mechanism.
+The MIPS and HPPA backtrace code has only very recently been updated
+to use GDB's new frame mechanism.  At present there are still a few
+problems, in particular backtraces through signal handlers do not
+work.
+
+People encountering problems with these architectures should consult
+GDB's web pages and mailing lists (http://www.gnu.org/software/gdb/)
+to see if there are updates.

-GDB's ARM target, in 6.0, has not been updated to use the new frame
-mechanism.
+PowerPC architecture support, in 6.1, does not use the new frame code.
 
-Fortunately the ARM target, in the GDB's mainline sources, has been
-updated so people encountering problems should consider downloading a
-more current GDB (http://www.gnu.org/software/gdb/current).
