Topic: Halt and Catch Fire



  
 Halt and Catch Fire - Wikipedia, the free encyclopedia
Halt and Catch Fire, known by its mnemonic HCF, denotes any of several undocumented and semi-mythical computer machine code instructions with destructive side-effects, supposedly included for test purposes on several well-known architectures going as far back as IBM System/360.
The instruction makes the processor enter a mode intended for manufacturing testing, in which it continuously performs memory read cycles from successive addresses, with no intervening instruction fetches.
The Motorola 6800 microprocessor was the first for which an HCF opcode became widely known.

 NodeWorks - Encyclopedia: F00f
Although technically not an example of either, the f00f is often considered an HCF instruction, or a killer poke.
Since the f00f bug has become common knowledge, the term is sometimes used to describe similar hardware design flaws, such as the Cyrix coma bug.
Operating System vendors responded by implementing workarounds that detected the condition and prevented the crash.

 White Space
In this particular case, I attempted to constrain the answer to the question “how should a literal carriage return, #x0D, be treated in a formatting object tree?” I thought there were three possibilities: treat it like a space, treate it like a line feed, #x0A, or discard it.
There were at least five answers, two others being: treat it as a line feed with line-feed-treatment set to preserve and treat it as an error (“halt and catch fire”).
Before we could answer this question, of course, we had to spend twenty minutes making sure we all understood the rules for numeric character references and attribute value normalization.

On investigating (and discovering the doors fully closed) I opened the case, cooled it off, and eventually decided that the problem was a drive cable (in a vinyl sheath) that had been too close to the the processor heat sink.
So, after all of my talk about SageTV vs. MCE, I just ordered a copy of Windows Media Center Edition 2005…
Unfortunately, someone (who had no reason to know not to) was by the other day and closed the doors.

Iacob Alin wondered if the various types would be PMCs (answer: Only those types which don't easily map to native types.) Florian Weimer wondered about trapping integer arithmetic.
Dan says these will be handled using Parrots standard exception handling mechanism (which doesn't actually exist yet, but signs in the wind suggest we might be getting a Halt and Catch Fire op to raise an exception).
