This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

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

static LLVM_ABI IntegerType * getInt64Ty(LLVMContext &C)

static LLVM_ABI IntegerType * getInt32Ty(LLVMContext &C)

static LLVM_ABI Type * getDoubleTy(LLVMContext &C)

LLVM Value Representation.

This class implements an extremely fast bulk output stream that can only output to a stream.

This is an optimization pass for GlobalISel generic memory operations.

format_object< Ts... > format(const char *Fmt, const Ts &... Vals)

These are helper functions used to produce formatted output.
