Kernel debugging
=================
Remote debugging over serial lines works fine, but the kernel
debugging code in here has not been tested in years. Van Jacobson has
better kernel debugging, but the UC lawyers won't let FSF have it.
Something goes here on how to set up a 64 bit build.

Known bugs:
* Under Ultrix 4.2 (DECstation-3100) or Alphas under OSF/1, we have
seen problems with backtraces after interrupting the inferior out
of a read(). The problem is caused by ptrace() returning an
incorrect value for the frame pointer register (register 15 or
30). As far as we can tell, this is a kernel problem. Any help
with this would be greatly appreciated.
* Under Ultrix 4.4 (DECstation-3100), setting the TERMCAP environment
variable to a string without a trailing ':' can cause GDB to dump
core upon startup. Although the core file makes it look as though
GDB code failed, the crash actually occurs within a call to the
termcap library function tgetent(). The problem can be solved by
using the GNU Termcap library.
Alphas running OSF/1 (versions 1.0 through 2.1) have the same buggy
termcap code, but GDB behaves strangely rather than crashing.
* On DECstations there are warnings about shift counts out of range in
various BFD modules. None of them is a cause for alarm, they are actually
a result of bugs in the DECstation compiler.
* Notes for the DEC Alpha using OSF/1:
The debugging output of native cc has two known problems; we view these
as compiler bugs.
The linker miscompacts symbol tables, which causes gdb to confuse the
type of variables or results in `struct <illegal>' type outputs.
dbx has the same problems with those executables. A workaround is to
specify -Wl,-b when linking, but that will increase the executable size
considerably.
If a structure has incomplete type in one file (e.g., "struct foo *"
without a definition for "struct foo"), gdb will be unable to find the
structure definition from another file.
It has been reported that the Ultrix 4.3A compiler on decstations has the
same problems.
* Notes for Solaris 2.x, using the SPARCworks cc compiler:
You have to compile your program with the -xs option of the SPARCworks
compiler to be able to debug your program with gdb.
Under Solaris 2.3 you also need patch 101409-03 (Jumbo linker patch).
Under Solaris 2.2, if you have patch 101052 installed, make sure
that it is at least at revision 101052-06.
* Under Irix 5 for SGIs, you must have installed the `compiler_dev.hdr'
subsystem that is on the IDO CD, otherwise you will get complaints
that certain files such as `/usr/include/syms.h' cannot be found.
* Under Irix 6 you must build with GCC. The vendor compiler reports
as errors certain assignments that GCC considers to be warnings.
GDB can produce warnings about symbols that it does not understand.
By default, these warnings are disabled. You can enable them by
executing `set complaint 10' (which you can put in your ~/.gdbinit if
you like). I recommend doing this if you are working on a compiler,
assembler, linker, or GDB, since it will point out problems that you
may be able to fix. Warnings produced during symbol reading indicate
some mismatch between the object file and GDB's symbol reading code.
In many cases, it's a mismatch between the specs for the object file
format, and what the compiler actually outputs or the debugger
actually understands.
