Allow failures on nightly (#143) 2018-11-15 13:11:10 +01:00
Jef e11ba15373 Remove `Box<[Target]>` from `Instruction` (#141)
This also allows `Instruction` to be `Copy`, which massively speeds
up `<Instructions as Clone>::clone` since it can now just `memcpy`
the bytes using SIMD instead of having to switch on every single
element. I haven't looked at the disassembly of `InstructionIter::next`
yet, it could be that there are even more improvements yet to be gained
from either:

* Only doing work on `BrTable` (this might already be the case depending
  on the whims of the optimiser)
* Using `unsafe` to make it a noop (we really don't want to do this,
  obviously, since it means that `Instructions` has to be immovable)

Leonardo Yvens 9db7896e48 implement from and into RuntimeValue for i8, u8, i16 and u16 (#104)
This works under the assumption that these values
are represented as an `I32` in WASM, which seems
reasonable.

Leonardo Yvens 75406dd8ff Use transmute instead of casts In RuntimeValue conversion. (#102)
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.
