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

pub fn generate_local_symbol_name(&self, prefix: &str) -> String

Generates a new symbol name with the given prefix. This symbol name must only be used for definitions with internal or private linkage.

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

Looks up debug source information about a BytePos.

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

Gets declared value by name.

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

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

pub(crate) unsafe 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 a LLVM type that has at most the required alignment, and exactly the required size, as a best-effort padding array.

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

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

type CodegenCx = CodegenCx<'ll, 'tcx>

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

fn data_layout(&self) -> &TargetDataLayout

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

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

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

fn target_spec(&self) -> &Target

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

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

impl<'ll, 'tcx> IntrinsicCallMethods<'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
)

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.

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::Value) -> 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 Value
) -> 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>

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 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<...>).

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.
