Migrate code to new asm! syntax #1
Description
I was hoping to experiment with this repo a little bit to see if I could use Rust for implementing new built-in DOS commands for dosbox-staging, but ATM it does not compile.
Nightly transitioned to new asm! syntax; old syntax can still be used via llvm_asm! (but somehow it does not work for me), but perhaps it would be better to move to new syntax right away.
rust-lang/rust#70173
rust-lang/rust#68404
Right now, the code fails to compile with several errors like this one:
error: the legacy LLVM-style asm! syntax is no longer supported
--> src/dos/io.rs:4:9

6 | | : "={al}"(ret)
7 | | : "{dx}"(port)

= note: consider migrating to the new asm! syntax specified in RFC 2873
= note: alternatively, switch to llvm_asm! to keep your code working as it is

Thanks for the report. I think I'm going to move the
asm!macro tollvm_asm!once and then to the newasm!.Merge pull request #2 from o8vm/change-to-newasm

New asm syntax is supported, and the build environment has been redesigned. This issue has been fixed and the build is now easier. If the issue persists, please open a new issue.
