Expand description

There is one CodegenCx per compilation unit. Each one has its own LLVM llvm::Context so that several compilation units may be optimized in parallel. All other LLVM data structures in the CodegenCx are tied to that llvm::Context.

§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>>

§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.

source§

impl CodegenCx<'_, '_>

source

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.

source

pub(crate) fn coverageinfo_finalize(&self)

source

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.

source§

impl CodegenCx<'_, '_>

source

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

Looks up debug source information about a BytePos.

source§

impl<'ll, 'tcx> CodegenCx<'ll, 'tcx>

source

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.

source

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.

source

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.

source

pub 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.

source

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).

source

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.

source

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

Gets declared value by name.

source

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

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

source§
