wasm64 support There is still some upstream llvm work needed before this can land.

Cleanup LLVM debuginfo module docs

2021-03-20T21:38:49+00:00

* Use Markdown list syntax and unindent a bit to prevent Markdown interpreting the nested lists as code blocks * A few more small typographical cleanups

Move debuginfo docs from `doc.rs` module to `doc.md` file

2021-03-20T21:38:49+00:00

And use `#[doc = include_str!("doc.md")]` in `mod.rs` so the docs are rendered as if they were inline in the root module.

Use u32 over Option in DebugLoc ~~Changes `Option` fields in `DebugLoc` to `Option`. Since the respective fields (`line` and `col`) are guaranteed to be 1-based, this layout optimization is a freebie.~~ EDIT: Changes `Option` fields in `DebugLoc` to `u32`. As `@bugadani` pointed out, an `Option` is probably an unnecessary layer of abstraction since the `None` variant is always used as `UNKNOWN_LINE_NUMBER` (which is just `0`). Also, `SourceInfo` in `metadata.rs` already uses a `u32` instead of an `Option` to encode the same information, so I think this change is warranted. Since `@jyn514` raised some concerns over measuring performance in a similar PR (#82255), does this need a perf run?

Rollup merge of #82057 - upsuper-forks:cstr, r=davidtwco,wesleywiser

Replace const_cstr with cstr crate This PR replaces the `const_cstr` macro inside `rustc_data_structures` with `cstr` macro from [cstr](https://crates.io/crates/cstr) crate. The two macros basically serve the same purpose, which is to generate `&'static CStr` from a string literal. `cstr` is better because it validates the literal at compile time, while the existing `const_cstr` does it at runtime when `debug_assertions` is enabled. In addition, the value `cstr` generates can be used in constant context (which is seemingly not needed anywhere currently, though).
