Fields

tcx: TyCtxt<'tcx>

scx: GenericCx<'ll, SCx<'ll>>

use_dll_storage_attrs: bool

tls_model: ThreadLocalMode

codegen_unit: &'tcx CodegenUnit<'tcx>

instances: RefCell<FxHashMap<Instance<'tcx>, &'ll Value>>

Cache instances of monomorphic and polymorphic items

vtables: RefCell<FxHashMap<(Ty<'tcx>, Option<ExistentialTraitRef<'tcx>>), &'ll Value>>

Cache generated vtables

const_str_cache: RefCell<FxHashMap<String, &'ll Value>>

Cache of constant strings,

const_globals: RefCell<FxHashMap<&'ll Value, &'ll Value>>

Cache of emitted const globals (value -> global)

statics_to_rauw: RefCell<Vec<(&'ll Value, &'ll Value)>>

List of globals for static variables which need to be passed to the LLVM function ReplaceAllUsesWith (RAUW) when codegen is complete. (We have to make sure we don’t invalidate any Values referring to constants.)

used_statics: RefCell<Vec<&'ll Value>>

Statics that will be placed in the llvm.used variable See https://llvm.org/docs/LangRef.html#the-llvm-used-global-variable for details

compiler_used_statics: RefCell<Vec<&'ll Value>>

Statics that will be placed in the llvm.compiler.used variable See https://llvm.org/docs/LangRef.html#the-llvm-compiler-used-global-variable for details

type_lowering: RefCell<FxHashMap<(Ty<'tcx>, Option<VariantIdx>), &'ll Type>>

Mapping of non-scalar types to llvm types.

scalar_lltypes: RefCell<FxHashMap<Ty<'tcx>, &'ll Type>>

Mapping of scalar types to llvm types.

coverage_cx: Option<CguCoverageContext<'ll, 'tcx>>

Extra per-CGU codegen state needed when coverage instrumentation is enabled.

dbg_cx: Option<CodegenUnitDebugContext<'ll, 'tcx>>

eh_personality: Cell<Option<&'ll Value>>

eh_catch_typeinfo: Cell<Option<&'ll Value>>

rust_try_fn: Cell<Option<(&'ll Type, &'ll Value)>>

intrinsics: RefCell<FxHashMap<&'static str, (&'ll Type, &'ll Value)>>

local_gen_sym_counter: Cell<usize>

A counter that is used for generating local symbol names

renamed_statics: RefCell<FxHashMap<DefId, &'ll Value>>

codegen_static will sometimes create a second global variable with a different type and clear the symbol name of the original global. global_asm! needs to be able to find this new global so that it can compute the correct mangled symbol name to insert into the asm.

Methods from Deref<Target = GenericCx<'ll, SCx<'ll>>>

pub(crate) fn get_metadata_value(&self, metadata: &'ll Metadata) -> &'ll Value

pub(crate) fn get_function(&self, name: &str) -> Option<&'ll Value>

pub(crate) fn get_md_kind_id(&self, name: &str) -> MetadataKindId

pub(crate) fn create_metadata(&self, name: String) -> Option<&'ll Metadata>

pub(crate) fn set_metadata<'a>( &self, val: &'a Value, kind_id: impl Into<MetadataKindId>, md: &'ll Metadata, )

A wrapper for llvm::LLVMSetMetadata, but it takes Metadata as a parameter instead of Value.

pub(crate) fn declare_global(&self, name: &str, ty: &'ll Type) -> &'ll Value

Declare a global value.

If there’s a value with the same name already declared, the function will return its Value instead.

pub(crate) fn type_named_struct(&self, name: &str) -> &'ll Type

pub(crate) fn set_struct_body( &self, ty: &'ll Type, els: &[&'ll Type], packed: bool, )

pub(crate) fn type_void(&self) -> &'ll Type

pub(crate) fn type_token(&self) -> &'ll Type

pub(crate) fn type_metadata(&self) -> &'ll Type

pub(crate) fn type_ix(&self, num_bits: u64) -> &'ll Type

x Creates an integer type with the given number of bits, e.g., i24

pub(crate) fn type_vector(&self, ty: &'ll Type, len: u64) -> &'ll Type

pub(crate) fn func_params_types(&self, ty: &'ll Type) -> Vec<&'ll Type>

pub(crate) fn llcx(&self) -> &'ll Context

pub(crate) fn isize_ty(&self) -> &'ll Type

pub(crate) fn type_variadic_func( &self, args: &[&'ll Type], ret: &'ll Type, ) -> &'ll Type

pub(crate) fn type_i1(&self) -> &'ll Type

pub(crate) fn type_struct(&self, els: &[&'ll Type], packed: bool) -> &'ll Type

Trait Implementations

impl<'ll> Borrow<SCx<'ll>> for FullCx<'ll, '_>

fn borrow(&self) -> &SCx<'ll>

Immutably borrows from an owned value.

impl<'ll, 'tcx> Deref for FullCx<'ll, 'tcx>

type Target = GenericCx<'ll, SCx<'ll>>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
