pub(crate) fn mcdc_parameters( &mut self, fn_name: &'ll Value, hash: &'ll Value, bitmap_bytes: &'ll Value, )

Emits a call to llvm.instrprof.mcdc.parameters.

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

source

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

source

pub(crate) 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

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

Looks up debug source information about a BytePos.

source

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.

source

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.

source

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.

source

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.

source

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).

source

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.

source

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

Gets declared value by name.

source

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

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

source

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.
