Provides ErrorOr smart pointer.

Represents either an error or a value T.

std::error_code getError() const

Lightweight error class with error context and mandatory checking.

static ErrorSuccess success()

Create a success value.

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.

static ErrorOr< std::unique_ptr< MemoryBuffer > > getFile(const Twine &Filename, bool IsText=false, bool RequiresNullTerminator=true, bool IsVolatile=false, std::optional< Align > Alignment=std::nullopt)

Open the specified file as a MemoryBuffer, returning a new MemoryBuffer if successful,...

StringRef - Represent a constant reference to a string, i.e.

Triple - Helper class for working with autoconf configuration names.

LLVM_ABI void setObjectFormat(ObjectFormatType Kind)

Set the object file format.

LLVM_ABI void setTriple(const Twine &Str)

Set all components to the new triple Str.

bool isNVPTX() const

Tests whether the target is NVPTX (32- or 64-bit).

LLVM_ABI void setOS(OSType Kind)

Set the operating system (third) component of the triple to a known type.

LLVM_ABI void setArch(ArchType Kind, SubArchType SubArch=NoSubArch)

Set the architecture (first) component of the triple to a known type.

LLVM_ABI void setVendor(VendorType Kind)

Set the vendor (second) component of the triple to a known type.

The instances of the Type class are immutable: once they are created, they are never changed.
