pioasm-wasm's Issues

pioasm fails with cryptic error messages

When you feed an invalid program, pioasm fails with a cryptic error message.

For instance, given the following input:

jmp 1

you'll get an error that says: exception thrown: 5322392 instead of the expected output (that you get from running the command line version of pioasm):

input.pio:2.1-5: instruction is invalid outside of a program
    2 | jmp 1
