So far, so good.

Now, in x86, it is possible for user mode software to change modes 
without OS intervention.  E.g. to change from 32 to 16 bit mode, etc.

Now, which mode does your user level exception handler run in?

Should it automatically save the existing mode, and start in some safe mode?

What happens if there is lots of existing code using user level 
exception handlers.  And now you, Mr. Computer Architect, want to create 
a new mode - say "72 bit address mode".

Q: what mode should the user level exception handler run in? The new 
mode? That will break existing code.  The old mode?

Q: if you run in the old mode, can the existing user level exception 
handler in the old mode still do its job for the code in the new mode?

Often such handlers decode instructions. How can they decode 
instructions in modes that did not exist when they were written?
Heck, it's not just a question of nw modes - you might add new 
instructions in an existing mode. (For this reason, I advocate an 
"instruction decoding API" - something that you call that tells you 
everything that you might need to know about an instruction.  This API 
could be implemented in user level software, or by the OS - but if you 
are a CPU vendor, you may want to do it in PALcode or microcode, which 
you can update far more easily than you can update software in umpteen 
OSes.)

Often such handlers look at addresses.  How can a handler handle an 
address larger, or otherwise different, than existed when it was 
originally created?

These problems are solvable.

But they take work to solve.

And you cannot just assume that existing OSes are "safe" for user level 
exceptions.  Sometimes they break in quite unexpected ways.  Ways that 
result in the cancellation and disabling and withdrawal of major 
features, even in shipping silicon.  (Not my project.)

You have to work through the issues.




I *like* lightweight user level exceptions.

But sometimes I am happy that they aren't very common. Because they 
greatly increase the difficulty of getting other new features deployed.
And overall, that may be the reason they aren't so common: they make 
other things more difficult. So perhaps they, user level exceptions, 
existed at some point in time - note that Intel x86 supports them in the 
ISA, and MS DOS certainly had them - but they broke along they way, got 
in the way of new features and were disabled - and nobody bothered to 
fix them.


I think user level exceptions are like context switching of state.  They 
are a political problem that requires a technical solution.
The technical solutions so far have not paid attention to the business 
issues.

(By the way, it annoys the heck out of me when people talk about user 
level interrupt handlers.  Usually they mean things like floating point 
exceptions - synchronoys evehnts, niot asynch interrupts.)
