Wasmtime GitHub notifications bot (Oct 17 2023 at 00:41):cfallin opened PR #7263 from cfallin:pcc-two-sided-range to bytecodealliance:main:
This is needed for soundness when verifying accesses to memtype fields: it's not enough to know that we're accessing an offset in
0up tofield_offsetinclusive, we need to know the access is actually tofield_offset.The simplest change that validates this turned out to be the most general one: making ranges two-sided rather than one-sided. The transform is mostly mechanical, but a few new tests verify that ranges are updated on both sides, and some fail-tests verify that "fuzzily imprecise" pointers to struct fields fail to validate.

:bike: :paintbrush: Maybe we should just call this
Range? That matches the text format.
