* 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.
* 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
Casts have arithmetic semantics, and under some build configurations
Rust will panic when encountering an arithmetic overflow.
Use a transmute instead since it's what we mean.
The previous code worked, but still I added a test for good measure.
* 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.
* 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.
