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
.

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

linkage.

pub(crate) fn coverageinfo_finalize(&self)
sourcefn get_pgo_func_name_var(&self, instance: Instance<'tcx>) -> &'ll Value
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
.
sourcefn define_unused_fn(&self, def_id: DefId)
fn define_unused_fn(&self, def_id: DefId)
Functions with MIR-based coverage are normally codegenned only if
called. LLVM coverage tools typically expect every function to be
defined (even if unused), with at least one call to LLVM intrinsic
instrprof.increment
.
Codegen a small function that will never be called, with one counter that will never be incremented.
For used/called functions, the coverageinfo was already added to the
function_coverage_map
(keyed by function Instance
) during codegen.
But in this case, since the unused function was not previously
codegenned, collect the coverage CodeRegion
s from the MIR and add
them. Since the function is never called, all of its CodeRegion
s can be
added as unreachable_region
s.

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

.

sourcepub fn declare_global(&self, name: &str, ty: &'ll Type) -> &'ll Value
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.
sourcepub fn declare_cfn(
&self,
name: &str,
unnamed: UnnamedAddr,
fn_type: &'ll Type
) -> &'ll Value
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.
sourcepub fn declare_entry_fn(
&self,
name: &str,
callconv: CallConv,
unnamed: UnnamedAddr,
fn_type: &'ll Type
) -> &'ll Value
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.
sourcepub fn declare_fn(
&self,
name: &str,
fn_abi: &FnAbi<'tcx, Ty<'tcx>>,
instance: Option<Instance<'tcx>>
) -> &'ll Value
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.
sourcepub fn define_global(&self, name: &str, ty: &'ll Type) -> Option<&'ll Value>
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).
sourcepub fn define_private_global(&self, ty: &'ll Type) -> &'ll Value
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.
sourcepub fn get_declared_value(&self, name: &str) -> Option<&'ll Value>
pub fn get_declared_value(&self, name: &str) -> Option<&'ll Value>
Gets declared value by name.
sourcepub fn get_defined_value(&self, name: &str) -> Option<&'ll Value>
pub fn get_defined_value(&self, name: &str) -> Option<&'ll Value>
Gets defined or externally defined (AvailableExternally linkage) value by name.
