Tagged union holding either a T or a Error.
Error takeError()
Take ownership of the stored error.
reference get()
Returns a reference to the stored T value.
This is an important class for using LLVM in a threaded context.
StringRef - Represent a constant reference to a string, i.e.
The instances of the Type class are immutable: once they are created, they are never changed.
static Expected< MemoryBufferRef > findBitcodeInObject(const ObjectFile &Obj)
Finds and returns bitcode embedded in the given object file, or an error code if not found.
static Expected< std::unique_ptr< IRObjectFile > > create(MemoryBufferRef Object, LLVMContext &Context)
static Expected< OwningBinary< ObjectFile > > createObjectFile(StringRef ObjectPath)
static Expected< std::unique_ptr< SymbolicFile > > createSymbolicFile(MemoryBufferRef Object, llvm::file_magic Type, LLVMContext *Context, bool InitContent=true)
SymbolicFile(unsigned int Type, MemoryBufferRef Source)
static bool isSymbolicFile(file_magic Type, const LLVMContext *Context)
#define llvm_unreachable(msg)
Marks that the current location is not supposed to be reachable.
This is an optimization pass for GlobalISel generic memory operations.
file_magic identify_magic(StringRef magic)
Identify the type of a binary file based on how magical it is.
Error errorCodeToError(std::error_code EC)
Helper for converting an std::error_code to a Error.
void consumeError(Error Err)
Consume a Error without doing anything.
