(See clang’s CodeGenPGO::emitMCDCParameters for comparison.)

pub(crate) fn eh_catch_typeinfo(&self) -> &'ll Value

pub(crate) fn set_metadata<'a>( &self, val: &'a Value, kind_id: MetadataType, md: &'a Metadata, )

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

pub(crate) fn coverageinfo_finalize(&self)

fn covfun_section_name(&self) -> &CStr

Returns the section name to use when embedding per-function coverage information in the object file, according to the target’s object file format. LLVM’s coverage tools use information from this section when producing coverage reports.

Typical values are:

• __llvm_covfun on Linux
• __LLVM_COV,__llvm_covfun on macOS (includes __LLVM_COV, segment prefix)
• .lcovfun$M on Windows (includes $M sorting suffix)

fn get_pgo_func_name_var(&self, instance: Instance<'tcx>) -> &'ll Value

For LLVM codegen, returns a function-specific Value for a global string, to hold the function name passed to LLVM intrinsic instrprof.increment(). The Value is only created once per instance. Multiple invocations with the same instance return the same Value.

fn lookup_debug_loc(&self, pos: BytePos) -> DebugLoc

Looks up debug source information about a BytePos.

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 declare_cfn( &self, name: &str, unnamed: UnnamedAddr, fn_type: &'ll Type, ) -> &'ll Value

Declare a C ABI function.

Only use this for foreign function ABIs and glue. For Rust functions use declare_fn instead.

If there’s a value with the same name already declared, the function will update the declaration and return existing Value instead.

pub(crate) fn declare_entry_fn( &self, name: &str, callconv: CallConv, unnamed: UnnamedAddr, fn_type: &'ll Type, ) -> &'ll Value

Declare an entry Function

The ABI of this function can change depending on the target (although for now the same as declare_cfn)

If there’s a value with the same name already declared, the function will update the declaration and return existing Value instead.

pub(crate) fn declare_fn( &self, name: &str, fn_abi: &FnAbi<'tcx, Ty<'tcx>>, instance: Option<Instance<'tcx>>, ) -> &'ll Value

Declare a Rust function.

If there’s a value with the same name already declared, the function will update the declaration and return existing Value instead.

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

Declare a global with an intention to define it.

Use this function when you intend to define a global. This function will return None if the name already has a definition associated with it. In that case an error should be reported to the user, because it usually happens due to user’s fault (e.g., misuse of #[no_mangle] or #[export_name] attributes).

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

Declare a private global

Use this function when you intend to define a global without a name.

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

Gets declared value by name.

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

Gets defined or externally defined (AvailableExternally linkage) value by name.

pub(crate) fn should_assume_dso_local( &self, llval: &Value, is_declaration: bool, ) -> bool

Whether a definition or declaration can be assumed to be local to a group of libraries that form a single DSO or executable.

Return an LLVM type that has at most the required alignment, and exactly the required size, as a best-effort padding array.

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

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

fn clear_dbg_loc(&mut self)

fn get_dbg_loc(&self) -> Option<&'ll DILocation>

fn insert_reference_to_gdb_debug_scripts_section_global(&mut self)

fn set_var_name(&mut self, value: &'ll Value, name: &str)

impl<'ll, 'tcx> Deref for Builder<'_, 'll, 'tcx>

type Target = CodegenCx<'ll, 'tcx>

The resulting type after dereferencing.

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

Dereferences the value.

impl Drop for Builder<'_, '_, '_>

fn drop(&mut self)

Executes the destructor for this type.

impl<'tcx> FnAbiOfHelpers<'tcx> for Builder<'_, '_, 'tcx>

fn handle_fn_abi_err( &self, err: FnAbiError<'tcx>, span: Span, fn_abi_request: FnAbiRequest<'tcx>, ) -> !

Helper used for fn_abi_of_*, to adapt tcx.fn_abi_of_*(...) into a Self::FnAbiOfResult (which does not need to be a Result<...>).

type FnAbiOfResult = &'tcx FnAbi<'tcx, Ty<'tcx>>

The &FnAbi-wrapping type (or &FnAbi itself), which will be returned from fn_abi_of_* (see also handle_fn_abi_err).

impl HasDataLayout for Builder<'_, '_, '_>

fn data_layout(&self) -> &TargetDataLayout

impl HasTargetSpec for Builder<'_, '_, '_>

fn target_spec(&self) -> &Target

impl<'tcx> HasTyCtxt<'tcx> for Builder<'_, '_, 'tcx>

fn tcx(&self) -> TyCtxt<'tcx>

impl<'tcx> HasTypingEnv<'tcx> for Builder<'_, '_, 'tcx>

fn typing_env(&self) -> TypingEnv<'tcx>

fn param_env(&self) -> ParamEnv<'tcx>

FIXME(#132279): This method should not be used as in the future everything should take a TypingEnv instead. Remove it as that point.

impl<'ll, 'tcx> IntrinsicCallBuilderMethods<'tcx> for Builder<'_, 'll, 'tcx>

fn codegen_intrinsic_call( &mut self, instance: Instance<'tcx>, fn_abi: &FnAbi<'tcx, Ty<'tcx>>, args: &[OperandRef<'tcx, &'ll Value>], llresult: &'ll Value, span: Span, ) -> Result<(), Instance<'tcx>>

Remember to add all intrinsics here, in compiler/rustc_hir_analysis/src/check/mod.rs, and in library/core/src/intrinsics.rs; if you need access to any LLVM intrinsics, add them to compiler/rustc_codegen_llvm/src/context.rs. Returns Err if another instance should be called instead. This is used to invoke intrinsic default bodies in case an intrinsic is not implemented by the backend.

fn abort(&mut self)

fn assume(&mut self, val: Self::Value)

fn expect(&mut self, cond: Self::Value, expected: bool) -> Self::Value

fn type_test( &mut self, pointer: Self::Value, typeid: Self::Metadata, ) -> Self::Value

Trait method used to test whether a given pointer is associated with a type identifier.

fn type_checked_load( &mut self, llvtable: &'ll Value, vtable_byte_offset: u64, typeid: &'ll Metadata, ) -> Self::Value

Trait method used to load a function while testing if it is associated with a type identifier.

fn va_start(&mut self, va_list: &'ll Value) -> &'ll Value

Trait method used to inject va_start on the “spoofed” VaListImpl in Rust defined C-variadic functions.

fn va_end(&mut self, va_list: &'ll Value) -> &'ll Value

Trait method used to inject va_end on the “spoofed” VaListImpl before Rust defined C-variadic functions return.

impl<'tcx> LayoutOfHelpers<'tcx> for Builder<'_, '_, 'tcx>

fn handle_layout_err( &self, err: LayoutError<'tcx>, span: Span, ty: Ty<'tcx>, ) -> !

Helper used for layout_of, to adapt tcx.layout_of(...) into a Self::LayoutOfResult (which does not need to be a Result<...>).

type LayoutOfResult = TyAndLayout<'tcx, Ty<'tcx>>

The TyAndLayout-wrapping type (or TyAndLayout itself), which will be returned from layout_of (see also handle_layout_err).

fn layout_tcx_at_span(&self) -> Span

Span to use for tcx.at(span), from layout_of.

impl<'ll> StaticBuilderMethods for Builder<'_, 'll, '_>

fn get_static(&mut self, def_id: DefId) -> &'ll 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.
