- This is the first of a series of articles consisting mostly of mail
- items from Robert Elz about P1003 Draft 4. They have all been given to
- the appropriate section reviewers on the P1003 committee and will be
- taken into account during the Trial Use balloting process. They are
- interspersed here with comments by Doug Gwyn (marked -Gwyn) which
- arrived by mail after Draft 5 was available but before the Dallas
- Steering Group meeting. Comments from Don Kretsch (marked -Kretsch)
- were collected at the Dallas meeting. I have added some more (marked
- -jsq) while preparing these articles for posting. All the latter three
- people are members of the P1003 working group. Don Kretsch is also a
- member of X3J11 and is the main liaison between the two committees.
-
- The usual disclaimer applies: nothing posted in this newsgroup
- by a committee member necessarily represents the official
- position of IEEE, P1003, or any other organization.
-
- Submissions do not ordinarily sit around for a month before
- appearing in the newsgroup. The original poster explicitly
- requested that responses be collected and posted with his originals.
-
- The comments on the original remarks are not necessarily definitive,
- and the set of people who made them is pretty arbitrary.
- Further responses are solicited.

- Subject: Is SIGILL omitted from the list of "hardware" signals for good reason?
- >From: Robert Elz <munnari!kre@seismo.CSS.GOV>
-
- In P1003/D4, section 3.3.2 (Signal Processing), there are several
- mentions to a list of distinguished signals, being
-
- SIGTRAP SIGIOT SIGEMT SIGFPE SIGBUS and SIGSEGV
-
- These are the signals to which non-recoverable hardware errors
- should be mapped, the action taken upon return from a signal
- handler after one of these signals is undefined, and SIGABRT
- is to be mapped to one of these.
-
- I note the absense of SIGILL from this list, and wonder why?
-
- Was this deliberately omitted - in which case I object, as
- a SIGILL is quite likely the best choice for SIGABRT, and it
- certainly may be undefined what will happen upon return
- from a SIGILL signal handler. Or is this a mere oversight?
-
- [ SIGILL was added for Draft 5. For some reason, Draft 5
- still does not permit SIGABRT to be defined as SIGILL; I
- don't understand why not. I thought it was going to be
- allowed; only SIGFPE should be disallowed as SIGABRT. -Gwyn ]
