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

Sourcepub(crate) fn generate_local_symbol_name(&self, prefix: &str) -> String
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.

pub(crate) fn coverageinfo_finalize(&self)
Sourcefn covfun_section_name(&self) -> &CStr
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)
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
.

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