Decouple `rustc_hir::print` into `rustc_hir_pretty` by Centril · Pull Request #70344 · rust-lang/rust

Centril · 2020-03-24T02:43:38Z

High level summary:

The HIR pretty printer, rustc_hir::print is moved into a new crate rustc_hir_pretty.
rustc_ast_pretty and rustc_errors are dropped as rustc_hir dependencies.
The dependence on HIR pretty is generally reduced, leaving rustc_save_analysis, rustdoc, rustc_metadata, and rustc_driver as the remaining clients.

The main goal here is to reduce rustc_hir's dependencies and its size such that it can start and finish earlier, thereby working towards #65031.

The printing stuff isn't quite my wheelhouse.

src/librustc_typeck/check/expr.rs

                    &mut |db| {
-                        db.span_label(
-                            fn_decl.output.span(),
-                            format!("expected `{}` because of this return type", fn_decl.output,),


I wonder if this was always meant to print a Ty but accidentally printed HIR.

src/librustc_typeck/check/_match.rs

-                    return self.get_fn_decl(hir_id).map(|(fn_decl, _)| {
-                        (
-                            fn_decl.output.span(),
-                            format!("expected `{}` because of this return type", fn_decl.output),


This also looks like it might be meant to be a Ty not HIR.

sized_trait_bound_spans, maybe?

Yea I wasn't really satisfied with the current name, yours is better.

r=me after addressing #70344 (comment), the hir::FnRetTy -> Ty stuff is probably too messy.
