* Initial forward-edge CFI implementation Give the user the option to start all basic blocks that are targets of indirect branches with the BTI instruction introduced by the Branch Target Identification extension to the Arm instruction set architecture. Copyright (c) 2022, Arm Limited. * Refactor `from_artifacts` to avoid second `make_executable` (#1) This involves "parsing" twice but this is parsing just the header of an ELF file so it's not a very intensive operation and should be ok to do twice. * Address the code review feedback Copyright (c) 2022, Arm Limited.

…dealliance#7029) * Rename `Host*` things to avoid name conflicts with bindings. * Update to the latest resource-enabled wit files. * Adapting the code to the new bindings. * Update wasi-http to the resource-enabled wit deps. * Start adapting the wasi-http code to the new bindings. * Make `get_directories` always return new owned handles. * Simplify the `poll_one` implementation. * Update the wasi-preview1-component-adapter. FIXME: temporarily disable wasi-http tests. Add logging to the cli world, since stderr is now a reseource that can only be claimed once. * Work around a bug hit by poll-list, fix a bug in poll-one. * Comment out `test_fd_readwrite_invalid_fd`, which panics now. * Fix a few FIXMEs. * Use `.as_ref().trapping_unwrap()` instead of `TrappingUnwrapRef`. * Use `drop_in_place`. * Remove `State::with_mut`. * Remove the `RefCell` around the `State`. * Update to wit-bindgen 0.12. * Update wasi-http to use resources for poll and I/O. This required making incoming-body and outgoing-body resourrces too, to work with `push_input_stream_child` and `push_output_stream_child`. * Re-enable disabled tests, remove logging from the worlds. * Remove the `poll_list` workarounds that are no longer needed. * Remove logging from the adapter. That said, there is no replacement yet, so add a FIXME comment. * Reenable a test that now passes. * Remove `.descriptors_mut` and use `with_descriptors_mut` instead. Replace `.descriptors()` and `.descriptors_mut()` with functions that take closures, which limits their scope, to prevent them from invalid aliasing. * Implement dynamic borrow checking for descriptors. * Add a cargo-vet audit for wasmtime-wmemcheck. * Update cargo vet for wit-bindgen 0.12. * Cut down on duplicate sync/async resource types (#1) * Allow calling `get-directories` more than once (#2) For now `Clone` the directories into new descriptor slots as needed. * Start to lift restriction of stdio only once (#3) * Start to lift restriction of stdio only once This commit adds new `{Stdin,Stdout}Stream` traits which take over the job of the stdio streams in `WasiCtxBuilder` and `WasiCtx`. These traits bake in the ability to create a stream at any time to satisfy the API of `wasi:cli`. The TTY functionality is folded into them as while I was at it. The implementation for stdin is relatively trivial since the stdin implementation already handles multiple streams reading it. Built-in impls of the `StdinStream` trait are also provided for helper types in `preview2::pipe` which resulted in the implementation of `MemoryInputPipe` being updated to support `Clone` where all clones read the same original data. * Get tests building * Un-ignore now-passing test * Remove unneeded argument from `WasiCtxBuilder::build` * Fix tests * Remove some workarounds Stdio functions can now be called multiple times. * If `poll_oneoff` fails part-way through, clean up properly. Fix the `Drop` implementation for pollables to only drop the pollables that have been successfully added to the list. This fixes the poll_oneoff_files failure and removes a FIXME. --------- Co-authored-by: Alex Crichton <[email protected]>

I created a c++ version of the nstream test because it was impossible to pick the correct indirect function index in the rust version. The rust runtime seems need a lot more indirect calls than wasi-libc.
I also created a different version of the benchmark harness that enables us able to split the setup code out of the timing loop. Unfortunately, it seems to cause a ton of "dead_code" warnings that I'm not 100% sure how to fix.
