This ports all of the identity, no-op, simplification, and canonicalization
related optimizations over from being hand-coded to the `peepmatic` DSL. This
does not handle the branch-to-branch optimizations or most of the
divide-by-constant optimizations.
This commit implements an initial WASI C API that can be used to instantiate
and configure a WASI instance from C.
This also implements a `WasiBuilder` for the C# API enabling .NET hosts to bind
to Wasmtime's WASI implementation.
* generator: take an &mut GuestMemory
rather than pass the owned GuestMemory in, just give exclusive access
to it. Makes testing easier.
* tests: start transforming tests to check abi-level generated code as well
* finish lowering of test funcs
* tests: rename variables to more sensible names
* proptesting: reliably finds that we dont allow stuff to be right against end of memory!
* memory: fix off-by-one calc in GuestMemory::contains(&self, Region)
ty proptest!
also, refactored the Region::overlaps to be the same code but easier to
read.
* generator: better location information in GuestError
* testing: proptest generates memory areas, tests everything
This commit adds the skeleton of a new set of documentation for
`wasmtime` in the existing `docs` directory. This documentation is
organized and compiled with [mdbook] which the Rust project uses for
most of its own documentation as well. At a previous meeting we
brainstormed a rough skeleton of what the documentation in this book
would look like, and I've transcribed that here for an example of how
this is rendered and how it can be laid out. No actual documentation is
written yet.
This commit also additionally adds necessary support to auto-publish
both this book documentation and API documentation every time a commit
is pushed to the `master` branch. All HTML will be automatically pushed
to the `gh-pages` branch so long as the CI passes, and this should get
deployed to https://cranestation.github.io/wasmtime.
I've done a few dry-runs and I think this'll all work, but we'll likely
tweak a few things here and there after running this through CI to make
sure everything looks just as we'd like. My hope though is that after
this lands we can start actually filling out all the documentation and
being able to review it as well.

A recent mypy update started writing the .mypy_cache directory which we
don't want under version control. The cache is only used by the
experimental "mypy --incremental" mode which we don't use, but it is
always written anyway.
When the CRETONNE_DBG environment variable is set, send debug messages
to a file named cretonne.dbg.*.
The trace facility is only enabled when debug assertions are on.
An SSA value is usually biased towards a specific register class or a
stack slot, depending on the constraints of the instructions using it.
Represent this bias as an Affinity enum, and implement a merging
algorithm for updating an affinity to satisfy a new constraint.
Affinities will be computed as part of the liveness analysis. This is
not implemented yet.
