* Implement trap info in Lightbeam * Start using wasm-reader instead of wasmparser for parsing operators * Update to use wasm-reader, some reductions in allocation, support source location tracking for traps, start to support multi-value The only thing that still needs to be supported for multi-value is stack returns, but we need to make it compatible with Cranelift. * Error when running out of registers (although we'd hope it should be impossible) instead of panicking * WIP: Update Lightbeam to work with latest Wasmtime * WIP: Update Lightbeam to use current wasmtime * WIP: Migrate to new system for builtin functions * WIP: Update Lightbeam to work with latest Wasmtime * Remove multi_mut * Format * Fix some bugs around arguments, add debuginfo offset tracking * Complete integration with new Wasmtime * Remove commented code * Fix formatting * Fix warnings, remove unused dependencies * Fix `iter` if there are too many elements, fix compilation for latest wasmtime * Fix float arguments on stack * Remove wasm-reader and trap info work * Allocate stack space _before_ passing arguments, fail if we can't zero a xmm reg * Fix stack argument offset calculation * Fix stack arguments in Lightbeam * Re-add WASI because it somehow got removed during rebase * Workaround for apparent `type_alias_impl_trait`-related bug in rustdoc * Fix breakages caused by rebase, remove module offset info as it is unrelated to wasmtime integration PR and was broken by rebase * Add TODO comment explaining `lightbeam::ModuleContext` trait
This is the wasmtime-environ crate, which contains the implementations
of the ModuleEnvironment and FuncEnvironment traits from
cranelift-wasm. They effectively
implement an ABI for basic wasm compilation that defines how linear memories
are allocated, how indirect calls work, and other details. They can be used
for JITing, native object files, or other purposes.
