From 8121958fda43759fa94e3f74f7cdbb595ddcc0e5 Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Mon, 3 Mar 2025 18:59:30 +1100 Subject: [PATCH] Use `-Wunused_crate_dependencies` for compiler crates. It's very useful. There are some false positives involving integration tests in `rustc_pattern_analysis` and `rustc_serialize`. There is also a false positive involving `rustc_driver_impl`'s `rustc_randomized_layouts` feature. And I removed a `rustc_span` mention in a doc comment in `rustc_log` because it wasn't integral to the comment but caused a dev-dependency. --- Cargo.lock | 19 ------------------- compiler/rustc_ast_ir/Cargo.toml | 2 -- compiler/rustc_ast_lowering/Cargo.toml | 1 - compiler/rustc_ast_pretty/Cargo.toml | 5 ++++- compiler/rustc_attr_parsing/Cargo.toml | 3 --- compiler/rustc_codegen_ssa/Cargo.toml | 2 -- compiler/rustc_driver_impl/Cargo.toml | 2 +- compiler/rustc_driver_impl/src/lib.rs | 8 ++++++++ compiler/rustc_interface/Cargo.toml | 7 +++++-- compiler/rustc_log/Cargo.toml | 5 ----- compiler/rustc_log/src/lib.rs | 7 +------ compiler/rustc_metadata/Cargo.toml | 6 +++++- compiler/rustc_mir_build/Cargo.toml | 2 -- compiler/rustc_parse_format/Cargo.toml | 4 +++- compiler/rustc_pattern_analysis/src/lib.rs | 1 + .../tests/complexity.rs | 2 ++ .../tests/exhaustiveness.rs | 2 ++ .../tests/intersection.rs | 2 ++ compiler/rustc_query_impl/Cargo.toml | 2 -- compiler/rustc_query_system/Cargo.toml | 1 - compiler/rustc_sanitizers/Cargo.toml | 1 - compiler/rustc_serialize/src/lib.rs | 2 ++ compiler/rustc_serialize/tests/leb128.rs | 3 +++ compiler/rustc_serialize/tests/opaque.rs | 2 ++ compiler/rustc_smir/Cargo.toml | 1 - compiler/rustc_symbol_mangling/Cargo.toml | 1 - compiler/rustc_ty_utils/Cargo.toml | 1 - src/bootstrap/src/core/builder/cargo.rs | 1 + 28 files changed, 42 insertions(+), 53 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index e91116ade9e..1a8dea0b105 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3206,7 +3206,6 @@ dependencies = [ "rustc_data_structures", "rustc_macros", "rustc_serialize", - "rustc_span", ] [[package]] @@ -3225,7 +3224,6 @@ dependencies = [ "rustc_index", "rustc_macros", "rustc_middle", - "rustc_parse", "rustc_session", "rustc_span", "rustc_target", @@ -3260,7 +3258,6 @@ version = "0.0.0" dependencies = [ "itertools", "rustc_ast", - "rustc_data_structures", "rustc_lexer", "rustc_span", "thin-vec", @@ -3288,15 +3285,12 @@ dependencies = [ "rustc_ast", "rustc_ast_pretty", "rustc_attr_data_structures", - "rustc_data_structures", "rustc_errors", "rustc_feature", "rustc_fluent_macro", "rustc_hir", "rustc_lexer", "rustc_macros", - "rustc_middle", - "rustc_serialize", "rustc_session", "rustc_span", "thin-vec", @@ -3423,7 +3417,6 @@ dependencies = [ "rustc_abi", "rustc_arena", "rustc_ast", - "rustc_ast_pretty", "rustc_attr_parsing", "rustc_data_structures", "rustc_errors", @@ -3431,7 +3424,6 @@ dependencies = [ "rustc_fs_util", "rustc_hashes", "rustc_hir", - "rustc_hir_pretty", "rustc_incremental", "rustc_index", "rustc_macros", @@ -3879,7 +3871,6 @@ dependencies = [ "rustc_query_impl", "rustc_query_system", "rustc_resolve", - "rustc_serialize", "rustc_session", "rustc_span", "rustc_symbol_mangling", @@ -3954,7 +3945,6 @@ dependencies = [ name = "rustc_log" version = "0.0.0" dependencies = [ - "rustc_span", "tracing", "tracing-core", "tracing-subscriber", @@ -4043,13 +4033,11 @@ dependencies = [ name = "rustc_mir_build" version = "0.0.0" dependencies = [ - "either", "itertools", "rustc_abi", "rustc_apfloat", "rustc_arena", "rustc_ast", - "rustc_attr_parsing", "rustc_data_structures", "rustc_errors", "rustc_fluent_macro", @@ -4256,7 +4244,6 @@ version = "0.0.0" dependencies = [ "measureme 12.0.1", "rustc_data_structures", - "rustc_errors", "rustc_hashes", "rustc_hir", "rustc_index", @@ -4265,7 +4252,6 @@ dependencies = [ "rustc_serialize", "rustc_session", "rustc_span", - "thin-vec", "tracing", ] @@ -4290,7 +4276,6 @@ dependencies = [ "rustc_session", "rustc_span", "smallvec", - "thin-vec", "tracing", ] @@ -4328,7 +4313,6 @@ version = "0.0.0" dependencies = [ "bitflags", "rustc_abi", - "rustc_ast", "rustc_data_structures", "rustc_hir", "rustc_middle", @@ -4383,7 +4367,6 @@ name = "rustc_smir" version = "0.0.0" dependencies = [ "rustc_abi", - "rustc_ast", "rustc_data_structures", "rustc_hir", "rustc_hir_pretty", @@ -4425,7 +4408,6 @@ dependencies = [ "punycode", "rustc-demangle", "rustc_abi", - "rustc_ast", "rustc_data_structures", "rustc_errors", "rustc_hashes", @@ -4520,7 +4502,6 @@ version = "0.0.0" dependencies = [ "itertools", "rustc_abi", - "rustc_attr_parsing", "rustc_data_structures", "rustc_errors", "rustc_fluent_macro", diff --git a/compiler/rustc_ast_ir/Cargo.toml b/compiler/rustc_ast_ir/Cargo.toml index f54e9687d8c..76bdd9f7eb6 100644 --- a/compiler/rustc_ast_ir/Cargo.toml +++ b/compiler/rustc_ast_ir/Cargo.toml @@ -8,7 +8,6 @@ edition = "2024" rustc_data_structures = { path = "../rustc_data_structures", optional = true } rustc_macros = { path = "../rustc_macros", optional = true } rustc_serialize = { path = "../rustc_serialize", optional = true } -rustc_span = { path = "../rustc_span", optional = true } #
