I hard-coded an IRQ delay down-count in the Qupls4 core. The down-count delays accepting interrupts for ten clock cycles or about 40 instructions if an interrupt got deferred. The interrupt being deferred because interrupts got disabled by an instruction in the pipeline. I guessed 40 instructions would likely be enough for many cases where IRQs are disabled then enabled again. The issue is the pipeline is full of ISR instructions that should not be committed because the IRQs got disabled in the meantime. If the CPU were allowed to accept another IRQ right away, it could get stuck in a loop flushing the pipeline and reloading with the ISR routine code instead of progressing through the code where IRQs were disabled. I could create a control register for this count and allow it to be programmable. But I think that may not be necessary. It is possible that 40 instructions is not enough. In that case the CPU would advance in 40 instruction burps. Alternating between fetching ISR instructions and the desired instruction stream. On the other hand, a larger down-count starts to impact the IRQ latency. Tradeoffs… I suppose I could have the CPU increase the down-count if it is looping around fetching ISR instructions. The down-count would be reset to the minimum again once an interrupt enable instruction is executed. Complex…

A special jump and disable interrupts instruction to the next instruction might do it. The pipeline needs to be cleared of the external interrupt when interrupts are disabled, and the address reset. The issue then is that the interrupt gets lost, so it needs to be cached somewhere so that once interrupts are enabled again it can be processed. There could be multiple interrupts in the pipeline that need to be cached. Seeing as the address needs to be reset, an explicit jump instruction may not be necessary. The IP of the interrupted instruction could be used. I see now that a stack might be better than a FIFO as only a higher priority interrupt would be able to interrupt the lower one. Should they be processed in order of occurrence? Order of occurrence = FIFO, otherwise stack = FILO. Leave it to the user to decide? Out of order asynchronous interrupts probably are not a big deal. Hardware likely does not know what the order is, or care about it.

Another alternative is to allow ISRs to be interrupted by ISRs of higher
priority. All you need here is a clean and precise definition of priority
and when said priority gets associated with any given interrupt.
My 66000 goes so far as to never need to disable interrupts because all
interrupts of the same or lower priority are automatically disabled by
the priority of the current ISR/running-thread. That is, one arrives
at the ISR with interrupts enabled and in a reentrant state with the
priority given by the I/O MMU when device sent ISR message to MSI-X
queue.
If/when an ISR needs to be sure it is not interrupted, it can change
priority in 1 instruction to "highest" and have the system not allow
the I/O MMU to associate said "exclusive" priority with any device
interrupt. When ISR returns, priority reverts to priority at the time
the interrupt was taken. {No need to back down on priority} This only
requires that there are enough priorities to spare one exclusively to
the system.
EricP has argued that 8-I/O priority levels are enough. I argue that
64 priority levels are enough for {Guest OS, Host OS, HyperVisor}
to each have their own somewhat-coordinated structure of priorities.
AND further I argue that given one is designing a 64-bit machine,
that 64 priority levels are dé rigueur.

The above is one of the reasons EricP supports the pipeline notion that interrupts do NOT flush the pipe. Instead, the instruction in the pipe are allowed to retire (apace) and new instructions are inserted from the interrupt service point. As long as the instructions "IN" the pipe can deliver their results to their registers, and update µArchitectural state they "own", there is no reason to flush--AND--no corresponding reason to delay "taking" the interrupt. At the µArchitectural level, you, the designer, see both the front and the end of the pipeline, you can change what goes in the front and allow what was already in the pipe to come out the back. This requires dragging a small amount of information down the pipe, much like multi-threaded CPUs. > I could create a control register for this count and allow it to be > programmable.

The interrupt mask is set at fetch time to disable lower priority interrupts. I suppose disabling of interrupts by the OS could simply be ignored. The interrupt could only be taken if it is a higher priority than the current level. I had thought the OS might have good reason to disable interrupts. But maybe I am making things too complex.

As a general rule of thumb:: an instruction is not "performed" until
after it retires. {when you cannot undo its deeds}
Consider the case where you redirect the front of the pipe to an ISR and
an instruction already in the pipe raises an exception. Here, what I do
{and have done in the past} is to not retire instructions after the
exception, so the ISR is not delayed and IP ends up pointing at the
excepting instruction.
Since you started ISR before you retired DI, you can treat DI as an
exception. {DI after ISR control transfer}. If, on the other hand,
you perform DI at the front of the pipe, you don't "accept" the ISR
until EI.

The OS DOES have good reasons to DI "every once in a while", IIRC my
conversations with EricP, these are short sequences the OS needs
to be ATOMIC across all OS threads--and almost always without the
possibility that the ATOMIC event fails {which can happen in user code}.

It would only take a read of a slow IO device register to exceed it. I was thinking a simple and cheap way would be to use a variation of the single-step mechanism. An interrupt request would cause Decode to emit a special uOp with the single-step flag set and then stall, to allow the pipeline to drain the old stream before accepting the interrupt and redirecting Fetch to its handler. That way if there are and interrupt enable or disable instructions, or branch mispredicts, or pending exceptions in-flight they all are allowed to finish and the state to settle down. Pipelining interrupt delivery looks possible but gets complicated and expensive real quick.

Yes, exactly::
Consider a GBOoO processor that performs a LD R9,[deviceCR].
a) all earlier memory references have to be seen globally
...before this LD can be seen globally. {dozens of cycles}
b) this LD has to arrive at HostBridge. {dozens of cycles}
c) HostBrdge sends request down PCIe {hundreds of cycles}
d) device responds to LD {handful of cycles}
e) PCIe transports response to HB {hundreds of cycles}
f) HB transfers response to requestor {dozens of cycles}
g) CPU is allowed to re-enter OoO {handful of cycles}
Accesses to devices need to have most of the properties of
"Sequential Consistency" as defined by Lamport.
Now, several LDs [DeviceCRs] can be seen globally and in order
before the first (or all responses) but you are going to see all
that latency in the pipeline; but OoO memory requests are not one
of them.

If the base down count is too large (stuck interrupt) then an exception is processed. For instance if interrupts were disabled for 1000 clocks. I think the mechanism could work, complicated though. Treating the DI as an exception, as mentioned in another post would also work. It is a matter then of flushing the instructions between the DI and ISR.

Got fed up with trying to work out how get interrupts working. It turns out to be more challenging than I expected, no matter which way it is done. So, I decided to just poll for interrupts, getting rid of most of the IRQ logic. I added a branch-on-interrupt BOI instruction that works almost the same way as every other branch. Then the micro-op translator has been adapted to insert a polling branch periodically. It looks a lot simpler.

Did not want to go much over 1% the number of instructions executed. Not every instruction inserts a poll, so sometimes a poll is lacking. IDK how well it will work. Making it an instruction means it might also be used by software.

Both our guesses were wrong, and Scott (I think) was on the right
track - this is a signed / unsigned issue. A reduced test case is
void bar(unsigned long, long);
void foo(unsigned long u1)
{
long u3;
u1 = u1 / 10;
u3 = u1 % 10;
bar(u1,u3);
}
This is now https://gcc.gnu.org/bugzilla/show_bug.cgi?id=122911 .

Assigning to u1 changed the meaning, as Andrew Pinski noted; so the
jury is still out on what the actual problem is.
>This is now https://gcc.gnu.org/bugzilla/show_bug.cgi?id=122911 .
and a revised one at
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=122919>
(The announced attachment is not there yet.)
The latter case is interesting, because real_ca and spc became global,
and symbols[] is still local, and no assignment to real_ca happens
inside foo().
So one way the compiler could interpret this code might be that
real_ca gets one of the labels whose address is taken in some way
unknown to the compiler; the it has to preserve all the code reachable
through the labels.
Another way to interpret this code would be that symbols is not used,
so it is dead and can be optimized away. Consequently, none of the
addresses of any of the labels is ever taken, and the labels are not
used by direct jumps, either, so all the code reachable only by
jumping to the labels is unreachable and can be optimized away.
Apparently gcc takes the latter attitude if there are <=100 labels in
symbols, but maybe something like the former attitude if there are
>100 labels in symbols. This may appear strange, but gcc generally
tends to produce good code in relatively short time for Gforth (while
clang generates horribly slow code and takes extremely long in doing
so), and my guess is that having such a cutoff on doing the usual
analysis has something to do with gcc's superior performance.
I guess that if you treat symbols like in the original code (i.e.,
return it in one case), you can reduce the labels more without the
compiler optimizing everything away. I don't dare to predict when the
compiler will stop generating the inefficient variant. Maybe it has
to do with the cutoff.

An example which could be tested at run-time to verify correct
operation was not provided, so I had to do without.
In reducing compiler bugs, automated tools such as delta or
(much better) cvise are essential. Your test case was so
large that cvise failed, so a lot of manual work was required.
cvise uses a user-supplied "interestingness script" which returns
0 if the feature in question is there, or non-zero if it is
not there. For relatively simple cases like an ICE, it
can have two steps: a) check that compilation fails, and b)
check that the error messages is output.
Looking for a missed optimization is more difficult, especially
in the absence of a run-time test. It is then necessary to
a) check the source code that the interesting code is still there
b) compile the code (exiting if this fails)
c) verify the generated assembly that it still does the same
a) and c) are very easy to get wrong, and there were numerous
false reductions where cvise came up with something that the
scripts didn't catch.

That is what cvise does. It sometimes reduces code more than a
human would.

Your test case was so >large that cvise failed, so a lot of manual work was required. I have now done a manual reduction myself; essentially I left only the 3 variants of the VM instruction that performs 10/, plus all the surroundings, and I added code to ensure that spTOS, spb, and spc are not dead. You find the result at http://www.complang.tuwien.ac.at/anton/tmp/engine-fast-red.i The result of compiling this with gcc -I./../arch/amd64 -I. -Wall -g -O2 -fomit-frame-pointer -pthread -DHAVE_CONFIG_H -DFORCE_LL -DFORCE_REG -DDEFAULTPATH='".:/usr/local/lib/gforth/site-forth:/usr/local/lib/gforth/0.7.9_20251119:/usr/local/share/gforth/0.7.9_20251119:/usr/share/gforth/site-forth:/usr/local/share/gforth/site-forth"' -c -fno-gcse -fcaller-saves -fno-defer-pop -fno-inline -fwrapv -fno-strict-aliasing -fno-cse-follow-jumps -fno-reorder-blocks -fno-reorder-blocks-and-partition -fno-toplevel-reorder -falign-labels=1 -falign-loops=1 -falign-jumps=1 -fno-delete-null-pointer-checks -fcf-protection=none -fno-tree-vectorize -fno-lto -pthread -DENGINE=2 -fPIC -DPIC -o libengine-fast2-ll-reg-red.S -S engine-fast-red.i can be found at http://www.complang.tuwien.ac.at/anton/tmp/libengine-fast2-ll-reg-red.S Now the multiplier is permanently allocated to %r11, so searching for it won't help. However, if you search for "mulq", you will find the code generated for the three instances of the VM instruction. The first is optimized well, the second exhibits two mulqs and two shrqs, the third exhibits just one mulq, but two shrqs. - anton -- 'Anyone trying for "industrial quality" ISA should avoid undefined behavior.'
