* Add ARMv7 as CI test target
* Avoid UB in conversions from floating point
When truncating floating point values to integer values, we need to
avoid undefined behavior if the argument does not fit into the target
type which is currently impossible using casts of primitive types.
Hence, this reimplements those conversions using arbitrary precision
integers and rationals from the num crate.
* Remove hashbrown and use BTree{Map,Set} from the alloc crate
wasmi-validation must handle untrusted input and hence we switch from
Hash{Set,Map} (whether std's or hashbrown's) to BTree{Set,Map} to avoid
algorithmic complexity attacks while retaining no_std support.
Closes#183
* Improve memory locality of checking for duplicate exports
Using a sorted slice gives us the same O(N log N) worst case execution
time as using a BTreeMap, but using a single allocation as with HashMap,
so that we should see better memory locality and hence better constant
factors when checking for duplicate exports.

* The great move of validation
* Make validation compile
* Make it compile.
* Format it.
* Fix warnings.
* Clean.
* Make it work under no_std
* Move deny_floating_point to wasmi
* Rename validate_module2 → validate_module

* fmt
* Proofs
* Add better proof
* Get rid of unreachable in StackValueType
* Propagate error if frame stack overflown on create
* use checked sub instead of -
* Keep::count
* add default-enabled std feature
* use parity-wasm/std feature only if std is enabled
* drop dependency on std::io
* use hashmap_core instead of std::collections::HashMap
* disable std::error in no_std
* core and alloc all the things
* mention no_std in readme
* add no_std feature and use hashmap_core only on no_std
* rename the no_std feature to core
* drop dependency on byteorder/std
* simplify float impl macro
* remove some trailing whitespace
* use libm for float math in no_std
* add note about no_std panics of libm to readme
* Embed nan-preserving-float crate.
* Add no_std check to the Travis CI config
* add missing dev-dependency
* Move call_stack to Interpreter struct
* Accept func and args when creating the Interpreter
* Create a RunState to indicate whether the current interpreter is recoverable
* Add functionality to resume execution in Interpreter level
* Implement resumable execution in func
* Expose FuncInvocation and ResumableError
* Fix missing docs for FuncInvocation
* Add test for resumable invoke and move external parameter passing to start/resume_invocation
* Add comments why assert is always true

* Define Instruction Set.
* WIP
* WIP 2
* Tests
* Working
* Bunch of other tests.
* WIP
* WIP
* Use Vec instead of VecDeque.
* Calibrate the limits.
* Clean
* Clean
* Another round of cleaning.
* Ignore traces.
* Optimize value stack
* Optimize a bit more.
* Cache memory index.
* Inline always instruction dispatch function.
* Comments.
* Clean
* Clean
* Use vector to keep unresolved references.
* Estimate resulting size.
* do refactoring
* Validate the locals count in the begging
* Introduce Keep and DropKeep structs in isa
* Rename/Split Validator into Reader
* Document stack layout
* Remove println!
* Fix typo.
* Use .last / .last_mut in stack
* Update docs for BrTable.
* Review fixes.
* Merge.
* Add an assert that stack is empty after the exec
* Refactor TryInto → FromRuntimeValue.
Replace `TryInto<T, E>` with `FromRuntimeValue`.
The main difference is that `FromRuntimeValue` is implemented for the concrete type of the value we create, rather than on `RuntimeValue`. This makes more sense to me and seems more clear.
The `try_into` method is now implemented on `RuntimeValue` itself.
And finally, `FromRuntimeValue` has been made public.
* Impl AsRef<[RuntimeValue]> for RuntimeArgs
This impl can be used as an escape hatch if the user wants to use the inner slice.
* Little doc fixes for RuntimeArgs.
* Initial implementation
* Not use grow as it is makes debug builds very slow
* Use Pages::BYTE_SIZE for LINEAR_MEMORY_PAGE_SIZE
* Tidy docs.
* Use memory_units from git.
* Get rid of Stack error
* Add UnexpectedSignature error and remove Value err
* Publish FuncInstance::invoke
* Rename Trap to TrapKind
* Replace Trap with struct. Enum is now TrapKind
* Fixes
* Update value.rs
* Avoid reversing parameter types iter.
* Add impl From<TrapKind> for Trap
* Remove redundant clone in prepare_function_args.
* Use .into() to convert TrapKind into Trap
* Introduce Trap struct.
* get_local can't fail.
* Add MemoryOutOfBounds trap.
* from_little_endian use slice instead of vec.
* MemoryAccessOutOfBounds for mem get and set.
* from_little_endian conversion can't fail.
* call_indirect traps.
* DivisionByZero and InvalidConversionToInt
* Use traps in value to convey an error
* select: int condition on stack top
* if: int condition on stack top
* Assert pops.
* Another protions of assert pops
* Introduce ValueStack
Also, hide FunctionContext and remove some stale code
* Traps in execution
* Make it compile.
* Check args before invoke.
* Document RuntimeArgs.
* Update host.rs
* Add rustdoc for Trap.
