LLVM Value Representation.
@ BasicBlock
Various leaf nodes.
This is an optimization pass for GlobalISel generic memory operations.
@ Global
Append to llvm.global_dtors.
AtomicOrdering
Atomic ordering for LLVM's memory model.
This struct is a compact representation of a valid (non-zero power of two) alignment.
This class defines the default behavior for configurable aspects of ValueMap<>.
