"jit" feature not working on "current" nightly(2018-05-19)

I know that it is caused by dynasm but maybe you could update to dynasm 0.2 if it is possible. This is an awesome brainfuck interpreter/compiler project and it would be nice to keep it alive. Thanks.

I'll look into it. Thanks for calling it awesome!

It appears to be an incompatibility between dynasm and the current nightly. It was working for me on a two-week-old nightly, and then I just upgraded to the current nightly and it no longer builds. This is true for dynasm 0.2.0 as well.

[petoknm]

nice... could you maybe specify the exact version (date)? I really want to try the jit stuff... sounds super cool

[petoknm]

got it working on:

nightly-2018-04-04-x86_64-unknown-linux-gnu rustc 1.27.0-nightly (637ac17c5 2018-04-03)

Yes, that version should I hope work until dynasm updates.

I reported an issue to dynasm and sent them a PR that fixes the problem. So hopefully they will accept the PR and release a new version soon.
