Subject: bug#64613: Signalling byte ops should show up in backtraces
Date: Wed, 26 Jul 2023 19:07:27 +0200 [thread overview]
Message-ID: <39AB3348-8602-4678-9C7A-1039B36A7229@gmail.com> (raw)
In-Reply-To: <E6AE5145-7CC0-4517-B456-93D039E497BD@acm.org>
Now (82f5f3b8a2) the `aref` and `aset` byte-ops provide backtrace records for errors that are discovered in the fast path:
- index argument not a fixnum
- for vector and record arguments, index out of range
For other types there is no such help yet since we call out to Faref and Faset.
We need a general strategy for dealing with such call-outs from the bytecode engine. So far, the backtrace records have all been to cold paths with no new hot-path code.
