+/* The a29k user's guide documents well what the stacks look like.
+ But what isn't so clear there is how this interracts with the
+ symbols, or with GDB.
+ In the following saved_msp, saved memory stack pointer (which functions
+ as a memory frame pointer), means either
+ a register containing the memory frame pointer or, in the case of
+ functions with fixed size memory frames (i.e. those who don't use
+ alloca()), the result of the calculation msp + msize.
+
+ LOC_ARG, LOC_LOCAL - For GCC, these are relative to saved_msp.
+ For high C, these are relative to msp (making alloca impossible).
+ LOC_REGISTER, LOC_REGPARM - The register number is the number at the
+ time the function is running (after the prologue), or in the case
+ of LOC_REGPARM, may be a register number in the range 160-175.
+
+ The compilers do things like store an argument into memory, and then put out
+ a LOC_ARG for it, or put it into global registers and put out a
+ LOC_REGPARM. Thus is it important to execute the first line of
+ code (i.e. the line of the open brace, i.e. the prologue) of a function
+ before trying to print arguments or anything.
+
+ The following diagram attempts to depict what is going on in memory
+ (see also the _a29k user's guide_) and also how that interacts with
+ GDB frames. We arbitrarily pick fci->frame to point the same place
+ as the register stack pointer; since we set it ourself in
+ INIT_EXTRA_FRAME_INFO, and access it only through the FRAME_*
+ macros, it doesn't really matter exactly how we
+ do it. However, note that FRAME_FP is used in two ways in GDB:
+ (1) as a "magic cookie" which uniquely identifies frames (even over
+ calls to the inferior), (2) (in PC_IN_CALL_DUMMY [ON_STACK])
+ as the value of SP_REGNUM before the dummy frame was pushed. These
+ two meanings would be incompatible for the a29k if we defined
+ CALL_DUMMY_LOCATION == ON_STACK (but we don't, so don't worry about it).
+ Also note that "lr1" below, while called a frame pointer
+ in the user's guide, has only one function: To determine whether
+ registers need to be filled in the function epilogue.
+
+ Consider the code:
+ < call bar>
+ loc1: . . .
+ bar: sub gr1,gr1,rsize_b
+ . . .
+ add mfp,msp,0
+ sub msp,msp,msize_b
+ . . .
+ < call foo >
+ loc2: . . .
+ foo: sub gr1,gr1,rsize_f
+ . . .
+ add mfp,msp,0
+ sub msp,msp,msize_f

+@node Convex,,, Top
+@appendix Convex-specific info
+@cindex Convex notes
+
+Scalar registers are 64 bits long, which is a pain since
+left half of an S register frequently contains noise.
+Therefore there are two ways to obtain the value of an S register.
+
+@table @kbd
+@item $s0
+returns the low half of the register as an int
+
+@item $S0
+returns the whole register as a long long
+@end table
+
+You can print the value in floating point by using @samp{p/f $s0} or @samp{p/f $S0}
+to print a single or double precision value.
+
+@cindex vector registers
+Vector registers are handled similarly, with @samp{$V0} denoting the whole
+64-bit register and @kbd{$v0} denoting the 32-bit low half; @samp{p/f $v0}
+or @samp{p/f $V0} can be used to examine the register in floating point.
+The length of the vector registers is taken from @samp{$vl}.
+
+Individual elements of a vector register are denoted in the obvious way;
+@samp{print $v3[9]} prints the tenth element of register @kbd{v3}, and
+@samp{set $v3[9] = 1234} alters it.
+
+@kbd{$vl} and @kbd{$vs} are int, and @kbd{$vm} is an int vector.
+Elements of @kbd{$vm} can't be assigned to.
+
+@cindex communication registers
+@kindex info comm-registers
+Communication registers have names @kbd{$C0 .. $C63}, with @kbd{$c0 .. $c63}
+denoting the low-order halves. @samp{info comm-registers} will print them
+all out, and tell which are locked. (A communication register is
+locked when a value is sent to it, and unlocked when the value is
+received.) Communication registers are, of course, global to all
+threads, so it does not matter what the currently selected thread is.
+@samp{info comm-reg @var{name}} prints just that one communication
+register; @samp{name} may also be a communication register number
+@samp{nn} or @samp{0xnn}.
+@samp{info comm-reg @var{address}} prints the contents of the resource
+structure at that address.
+
+@kindex info psw
+The command @samp{info psw} prints the processor status word @kbd{$ps}
+bit by bit.
+
+@kindex set base
+GDB normally prints all integers in base 10, but the leading
+@kbd{0x80000000} of pointers is intolerable in decimal, so the default
+output radix has been changed to try to print addresses appropriately.
+The @samp{set base} command can be used to change this.
+
+@table @code
+@item set base 10
+Integer values always print in decimal.
+
+@item set base 16
+Integer values always print in hex.
+
+@item set base
+Go back to the initial state, which prints integer values in hex if they
+look like pointers (specifically, if they start with 0x8 or 0xf in the
+stack), otherwise in decimal.
+@end table
+
+@kindex set pipeline
+When an exception such as a bus error or overflow happens, usually the PC
+is several instructions ahead by the time the exception is detected.
+The @samp{set pipe} command will disable this.
+
+@table @code
+@item set pipeline off
+Forces serial execution of instructions; no vector chaining and no
+scalar instruction overlap. With this, exceptions are detected with
+the PC pointing to the instruction after the one in error.
+
+@item set pipeline on
+Returns to normal, fast, execution. This is the default.
+@end table
+
+@cindex parallel
+In a parallel program, multiple threads may be executing, each
+with its own registers, stack, and local memory. When one of them
+hits a breakpoint, that thread is selected. Other threads do
+not run while the thread is in the breakpoint.
+
+@kindex 1cont
+The selected thread can be single-stepped, given signals, and so
+on. Any other threads remain stopped. When a @samp{cont} command is given,
+all threads are resumed. To resume just the selected thread, use
+the command @samp{1cont}.
+
+@kindex thread
+The @samp{thread} command will show the active threads and the
+instruction they are about to execute. The selected thread is marked
+with an asterisk. The command @samp{thread @var{n}} will select thread @var{n},
+shifting the debugger's attention to it for single-stepping,
+registers, local memory, and so on.
+
+@kindex info threads
+The @samp{info threads} command will show what threads, if any, have
+invisibly hit breakpoints or signals and are waiting to be noticed.
+
+@kindex set parallel
+The @samp{set parallel} command controls how many threads can be active.
+
+@table @code
+@item set parallel off
+One thread. Requests by the program that other threads join in
+(spawn and pfork instructions) do not cause other threads to start up.
+This does the same thing as the @samp{limit concurrency 1} command.
+
+@item set parallel fixed
+All CPUs are assigned to your program whenever it runs. When it
+executes a pfork or spawn instruction, it begins parallel execution
+immediately. This does the same thing as the @samp{mpa -f} command.
+
+@item set parallel on
+One or more threads. Spawn and pfork cause CPUs to join in when and if
+they are free. This is the default. It is very good for system
+throughput, but not very good for finding bugs in parallel code. If you
+suspect a bug in parallel code, you probably want @samp{set parallel fixed.}
+@end table
+
+@subsection Limitations
+
+WARNING: Convex GDB evaluates expressions in long long, because S
+registers are 64 bits long. However, GDB expression semantics are not
+exactly C semantics. This is a bug, strictly speaking, but it's not one I
+know how to fix. If @samp{x} is a program variable of type int, then it
+is also type int to GDB, but @samp{x + 1} is long long, as is @samp{x + y}
+or any other expression requiring computation. So is the expression
+@samp{1}, or any other constant. You only really have to watch out for
+calls. The innocuous expression @samp{list_node (0x80001234)} has an
+argument of type long long. You must explicitly cast it to int.
+
+It is not possible to continue after an uncaught fatal signal by using
+@samp{signal 0}, @samp{return}, @samp{jump}, or anything else. The difficulty is with
+Unix, not GDB.
+
+I have made no big effort to make such things as single-stepping a
+@kbd{join} instruction do something reasonable. If the program seems to
+hang when doing this, type @kbd{ctrl-c} and @samp{cont}, or use
+@samp{thread} to shift to a live thread. Single-stepping a @kbd{spawn}
+instruction apparently causes new threads to be born with their T bit set;
+this is not handled gracefully. When a thread has hit a breakpoint, other
+threads may have invisibly hit the breakpoint in the background; if you
+clear the breakpoint gdb will be surprised when threads seem to continue
+to stop at it. All of these situations produce spurious signal 5 traps;
+if this happens, just type @samp{cont}. If it becomes a nuisance, use
+@samp{handle 5 nostop}. (It will ask if you are sure. You are.)
+
+There is no way in GDB to store a float in a register, as with
+@kbd{set $s0 = 3.1416}. The identifier @kbd{$s0} denotes an integer,
+and like any C expression which assigns to an integer variable, the
+right-hand side is casted to type int. If you should need to do
+something like this, you can assign the value to @kbd{@{float@} ($sp-4)}
+and then do @kbd{set $s0 = $sp[-4]}. Same deal with @kbd{set $v0[69] = 6.9}.

+ First, a special bit in the page table entry is used to cause
+ a trap when a specific page is written to. This avoids having
+ to overload watchpoints on the page protection bits. This makes
+ it possible for the kernel to easily decide if a trap was caused
+ by a watchpoint or by the user writing to protected memory and can

+ Second, the PA has a bit in the processor status word which causes
+ data memory breakpoints (aka watchpoints) to be disabled for a single
+ instruction. This bit can be used to avoid the overhead of unprotecting
+ and reprotecting pages when it becomes necessary to step over a watchpoint.
+
+
+ When the kernel receives a trap indicating a write to a page which
+ is being watched, the kernel performs a couple of simple actions. First
+ is sets the magic "disable memory breakpoint" bit in the processor
+ status word, it then sends a SIGTRAP to the process which caused the
+ trap.
+
+ GDB will take control and catch the signal for the inferior. GDB then
+ examines the PSW-X bit to determine if the SIGTRAP was caused by a
+ watchpoint firing. If so GDB single steps the inferior over the
+ instruction which caused the watchpoint to trigger (note because the
+ kernel disabled the data memory break bit for one instruction no trap
+ will be taken!). GDB will then determines the appropriate action to

+ the dummy calls the secret, undocumented routine _sr4export, which
+ calls a function in text space and can return to any space. Instead
+ of including fake instructions to represent saved registers, we
+ know that the frame is associated with the call dummy and treat it
+ specially.
+
+ The trailing NOPs are needed to avoid a bug in HPUX, BSD and OSF1
+ kernels. If the memory at the location pointed to by the PC is
+ 0xffffffff then a ptrace step call will fail (even if the instruction
+ is nullified).
+
+ The code to pop a dummy frame single steps three instructions
+ starting with the last mtsp. This includes the nullified "instruction"
+ following the ble (which is uninitialized junk). If the
+ "instruction" following the last BLE is 0xffffffff, then the ptrace
+ will fail and the dummy frame is not correctly popped.
+
+ By placing a NOP in the delay slot of the BLE instruction we can be
+ sure that we never try to execute a 0xffffffff instruction and
+ avoid the kernel bug. The second NOP is needed to keep the call
+ dummy 8 byte aligned. */
