From 93e4b6ef06888085dc60d073ca9d66f2d7282112 Mon Sep 17 00:00:00 2001 From: Nicholas Nethercote Date: Fri, 10 Jun 2022 11:18:06 +1000 Subject: [PATCH] Rename the `ConstS::val` field as `kind`. And likewise for the `Const::val` method. Because its type is called `ConstKind`. Also `val` is a confusing name because `ConstKind` is an enum with seven variants, one of which is called `Value`. Also, this gives consistency with `TyS` and `PredicateS` which have `kind` fields. The commit also renames a few `Const` variables from `val` to `c`, to avoid confusion with the `ConstKind::Value` variant. --- compiler/rustc_borrowck/src/type_check/mod.rs | 4 ++-- compiler/rustc_codegen_cranelift/src/base.rs | 2 +- .../rustc_codegen_cranelift/src/constant.rs | 6 ++--- .../src/debuginfo/type_names.rs | 8 +++---- .../rustc_codegen_ssa/src/mir/constant.rs | 4 ++-- .../rustc_const_eval/src/const_eval/mod.rs | 2 +- .../rustc_const_eval/src/interpret/operand.rs | 8 +++---- .../rustc_const_eval/src/interpret/util.rs | 4 ++-- .../src/transform/check_consts/qualifs.rs | 3 ++- .../src/transform/promote_consts.rs | 2 +- .../src/infer/canonical/canonicalizer.rs | 4 ++-- .../rustc_infer/src/infer/canonical/mod.rs | 2 +- .../src/infer/canonical/query_response.rs | 2 +- compiler/rustc_infer/src/infer/combine.rs | 10 ++++---- .../infer/error_reporting/need_type_info.rs | 6 ++--- compiler/rustc_infer/src/infer/freshen.rs | 2 +- compiler/rustc_infer/src/infer/fudge.rs | 2 +- .../src/infer/higher_ranked/mod.rs | 2 +- compiler/rustc_infer/src/infer/mod.rs | 4 ++-- .../rustc_infer/src/infer/nll_relate/mod.rs | 4 ++-- compiler/rustc_infer/src/infer/resolve.rs | 2 +- compiler/rustc_lint/src/builtin.rs | 2 +- compiler/rustc_middle/src/infer/canonical.rs | 2 +- compiler/rustc_middle/src/mir/mod.rs | 14 +++++------ compiler/rustc_middle/src/mir/pretty.rs | 11 +++++---- compiler/rustc_middle/src/ty/_match.rs | 2 +- compiler/rustc_middle/src/ty/consts.rs | 24 +++++++++---------- compiler/rustc_middle/src/ty/context.rs | 12 +++++----- compiler/rustc_middle/src/ty/diagnostics.rs | 2 +- compiler/rustc_middle/src/ty/error.rs | 2 +- compiler/rustc_middle/src/ty/fast_reject.rs | 6 ++--- compiler/rustc_middle/src/ty/flags.rs | 2 +- compiler/rustc_middle/src/ty/fold.rs | 14 +++++------ compiler/rustc_middle/src/ty/print/pretty.rs | 16 ++++++------- compiler/rustc_middle/src/ty/relate.rs | 4 ++-- .../rustc_middle/src/ty/structural_impls.rs | 8 +++---- compiler/rustc_middle/src/ty/subst.rs | 2 +- compiler/rustc_middle/src/ty/util.rs | 6 ++--- compiler/rustc_middle/src/ty/walk.rs | 2 +- .../src/build/expr/as_constant.rs | 4 ++-- .../src/thir/pattern/deconstruct_pat.rs | 2 +- .../rustc_mir_build/src/thir/pattern/mod.rs | 2 +- .../rustc_mir_transform/src/const_prop.rs | 4 ++-- .../src/const_prop_lint.rs | 2 +- compiler/rustc_mir_transform/src/inline.rs | 2 +- .../src/required_consts.rs | 2 +- compiler/rustc_monomorphize/src/collector.rs | 4 ++-- .../rustc_monomorphize/src/polymorphize.rs | 4 ++-- compiler/rustc_symbol_mangling/src/legacy.rs | 6 ++--- compiler/rustc_symbol_mangling/src/v0.rs | 4 ++-- .../rustc_trait_selection/src/opaque_types.rs | 4 ++-- .../src/traits/auto_trait.rs | 2 +- .../src/traits/const_evaluatable.rs | 10 ++++---- .../error_reporting/on_unimplemented.rs | 2 +- .../src/traits/fulfill.rs | 4 ++-- .../src/traits/project.rs | 12 +++++----- .../src/traits/query/normalize.rs | 4 ++-- .../src/traits/select/confirmation.rs | 4 ++-- .../src/traits/select/mod.rs | 4 ++-- .../rustc_trait_selection/src/traits/wf.rs | 8 +++---- compiler/rustc_traits/src/chalk/db.rs | 2 +- compiler/rustc_traits/src/chalk/lowering.rs | 6 ++--- compiler/rustc_typeck/src/check/check.rs | 2 +- .../rustc_typeck/src/check/compare_method.rs | 2 +- compiler/rustc_typeck/src/check/wfcheck.rs | 2 +- compiler/rustc_typeck/src/collect.rs | 2 +- .../src/constrained_generic_params.rs | 2 +- .../rustc_typeck/src/variance/constraints.rs | 6 ++--- src/librustdoc/clean/utils.rs | 4 ++-- ...egion_subtyping_basic.main.nll.0.32bit.mir | 2 +- ...egion_subtyping_basic.main.nll.0.64bit.mir | 2 +- .../clippy_lints/src/large_const_arrays.rs | 2 +- .../clippy_lints/src/large_stack_arrays.rs | 2 +- src/tools/clippy/clippy_utils/src/consts.rs | 2 +- 74 files changed, 173 insertions(+), 169 deletions(-) diff --git a/compiler/rustc_borrowck/src/type_check/mod.rs b/compiler/rustc_borrowck/src/type_check/mod.rs index e405baf7575dd..ae6b8e0ae30f7 100644 --- a/compiler/rustc_borrowck/src/type_check/mod.rs +++ b/compiler/rustc_borrowck/src/type_check/mod.rs @@ -378,7 +378,7 @@ impl<'a, 'b, 'tcx> Visitor<'tcx> for TypeVerifier<'a, 'b, 'tcx> { } else { let tcx = self.tcx();
