mk: Move from `-D warnings` to `#![deny(warnings)]`#31120

alexcrichton · 2016-01-22T17:47:54Z

This commit removes the -D warnings flag being passed through the makefiles to
all crates to instead be a crate attribute. We want these attributes always
applied for all our standard builds, and this is more amenable to Cargo-based
builds as well.

Note that all deny(warnings) attributes are gated with a cfg(stage0)
attribute currently to match the same semantics we have today

One change I also noticed was that the rustc_mir crate did not previously have an #[unstable] tag, which means that this compiles in stable Rust:

extern crate rustc_mir;

fn main() {}

I added the #[unstable] tag here, but I would be quite surprised if that actually caused breakage. @brson do you think it's worth adding to relnotes?

brson · 2016-01-22T18:15:44Z

@alexcrichton It may not be worth mentioning but I'll tag it and think about it later. Also nominating for beta, maybe just the rustc_mir crate fix.

Here's an issue to lint for this problem: #31122

alexcrichton · 2016-01-22T18:16:37Z

Oh let me rearrange the commits for the new unstable attribute to be in its own commit to be easily cherry-picked in that case.
