@poemm's update from today's standup: All tests are passing except memgrow/memsize (which WABT doesn't support) and floating point (which he hasn't implemented yet). He's now going to start implementing the EEI for pywebassembly 👏

@poemm update today: all (non-float) assert_return tests pass including memory.grow and memory.size. wrote PyEEI infrastructure, didn’t implement functions yet. next step is to read up on EVM design in py-evm/trinity.

@poemm update from yesterday: all assert_trap tests pass (except those involving floating point numbers), pushed test infrastructure

@poemm update from this morning:

Overhauled PyWebAssembly byte/little-endian encoding for i32,i64,f32,f64; now supports floating point using Python float type
passing floating point tests, except don’t know how to modify NaN’s significand like spec says, this is deprioritized for now, later will consider numpy.float32/64, decimal, or ctypes.c_float/c_double
also deprioritizing malformed, valid, linking tests since the sentinel may do these
