static LLVM_ABI CastInst * CreatePointerBitCastOrAddrSpaceCast(Value *S, Type *Ty, const Twine &Name="", InsertPosition InsertBefore=nullptr)

Create a BitCast or an AddrSpaceCast cast instruction.

static LLVM_ABI CastInst * CreatePointerCast(Value *S, Type *Ty, const Twine &Name="", InsertPosition InsertBefore=nullptr)

Create a BitCast, AddrSpaceCast or a PtrToInt cast instruction.

Predicate

This enumeration lists the possible predicates for CmpInst subclasses.

This is an important base class in LLVM.

This provides a helper for copying FMF from an instruction or setting specified flags.

Convenience struct for specifying and reasoning about fast-math flags.

Represents flags for the getelementptr instruction/expression.

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

LLVM Value Representation.

unsigned ID

LLVM IR allows to use arbitrary numbers as calling convention identifiers.

@ C

The default llvm calling convention, compatible with C.

This is an optimization pass for GlobalISel generic memory operations.
