From 5569e6b2053a6488c398d9bd8f8b48f2959a90bc Mon Sep 17 00:00:00 2001 From: Jubilee Young Date: Sun, 28 Sep 2025 14:40:39 -0700 Subject: [PATCH] remove explicit deref of AbiAlign for most methods Much of the compiler calls functions on Align projected from AbiAlign. AbiAlign impls Deref to its inner Align, so we can simplify these away. Also, it will minimize disruption when AbiAlign is removed. For now, preserve usages that might resolve to PartialOrd or PartialEq, as those have odd inference. --- src/abi/comments.rs | 2 +- src/abi/pass_mode.rs | 2 +- src/base.rs | 2 +- src/debuginfo/mod.rs | 2 +- src/debuginfo/types.rs | 6 ++---- src/unsize.rs | 6 +++--- src/value_and_place.rs | 6 +++--- 7 files changed, 12 insertions(+), 14 deletions(-) diff --git a/src/abi/comments.rs b/src/abi/comments.rs index c74efeb59f3f..d1b2b9a502ac 100644 --- a/src/abi/comments.rs +++ b/src/abi/comments.rs @@ -89,7 +89,7 @@ pub(super) fn add_local_place_comments<'tcx>( format!("{:?}", local), format!("{:?}", ty), size.bytes(), - align.abi.bytes(), + align.bytes(), if extra.is_empty() { "" } else { " " }, extra, )); diff --git a/src/abi/pass_mode.rs b/src/abi/pass_mode.rs index 2031842062d9..7a909a740b05 100644 --- a/src/abi/pass_mode.rs +++ b/src/abi/pass_mode.rs @@ -233,7 +233,7 @@ pub(super) fn from_casted_value<'tcx>( // It may also be smaller for example when the type is a wrapper around an integer with a // larger alignment than the integer. std::cmp::max(abi_param_size, layout_size), - u32::try_from(layout.align.abi.bytes()).unwrap(), + u32::try_from(layout.align.bytes()).unwrap(), ); let mut block_params_iter = block_params.iter().copied(); for (offset, _) in abi_params { diff --git a/src/base.rs b/src/base.rs index 41e11e1de616..2cc5b82ddd34 100644 --- a/src/base.rs +++ b/src/base.rs @@ -846,7 +846,7 @@ fn is_wide_ptr<'tcx>(fx: &FunctionCx<'_, '_, 'tcx>, ty: Ty<'tcx>) -> bool { let layout = fx.layout_of(fx.monomorphize(ty)); let val = match null_op { NullOp::SizeOf => layout.size.bytes(), - NullOp::AlignOf => layout.align.abi.bytes(), + NullOp::AlignOf => layout.align.bytes(), NullOp::OffsetOf(fields) => fx .tcx .offset_of_subfield( diff --git a/src/debuginfo/mod.rs b/src/debuginfo/mod.rs index 286e02b986b3..4c438742f3d2 100644 --- a/src/debuginfo/mod.rs +++ b/src/debuginfo/mod.rs @@ -304,7 +304,7 @@ pub(crate) fn define_static<'tcx>( entry.set(gimli::DW_AT_decl_file, AttributeValue::FileIndex(Some(file_id))); entry.set(gimli::DW_AT_decl_line, AttributeValue::Udata(line)); - entry.set(gimli::DW_AT_alignment, AttributeValue::Udata(static_layout.align.abi.bytes())); + entry.set(gimli::DW_AT_alignment, AttributeValue::Udata(static_layout.align.bytes())); let mut expr = Expression::new(); expr.op_addr(address_for_data(data_id)); diff --git a/src/debuginfo/types.rs b/src/debuginfo/types.rs index 25b922c8be4c..0d49f32373ca 100644 --- a/src/debuginfo/types.rs +++ b/src/debuginfo/types.rs @@ -166,7 +166,7 @@ fn tuple_type<'tcx>( let tuple_entry = self.dwarf.unit.get_mut(tuple_type_id); tuple_entry.set(gimli::DW_AT_name, AttributeValue::StringRef(self.dwarf.strings.add(name))); tuple_entry.set(gimli::DW_AT_byte_size, AttributeValue::Udata(layout.size.bytes())); - tuple_entry.set(gimli::DW_AT_alignment, AttributeValue::Udata(layout.align.abi.bytes())); + tuple_entry.set(gimli::DW_AT_alignment, AttributeValue::Udata(layout.align.bytes())); for (i, (ty, dw_ty)) in components.into_iter().enumerate() { let member_id = self.dwarf.unit.add(tuple_type_id, gimli::DW_TAG_member); @@ -178,9 +178,7 @@ fn tuple_type<'tcx>( member_entry.set(gimli::DW_AT_type, AttributeValue::UnitRef(dw_ty)); member_entry.set( gimli::DW_AT_alignment, - AttributeValue::Udata( - FullyMonomorphizedLayoutCx(tcx).layout_of(ty).align.abi.bytes(), - ), + AttributeValue::Udata(FullyMonomorphizedLayoutCx(tcx).layout_of(ty).align.bytes()), ); member_entry.set( gimli::DW_AT_data_member_location, diff --git a/src/unsize.rs b/src/unsize.rs index 643c7feb89a2..d994f3e32ec3 100644 --- a/src/unsize.rs +++ b/src/unsize.rs @@ -167,7 +167,7 @@ pub(crate) fn size_and_align_of<'tcx>( if layout.is_sized() { return ( fx.bcx.ins().iconst(fx.pointer_type, layout.size.bytes() as i64), - fx.bcx.ins().iconst(fx.pointer_type, layout.align.abi.bytes() as i64), + fx.bcx.ins().iconst(fx.pointer_type, layout.align.bytes() as i64), ); } @@ -186,7 +186,7 @@ pub(crate) fn size_and_align_of<'tcx>( // times the unit size.
