Primary interface to the complete machine description for the target machine.

This pass provides access to the codegen interfaces that are needed for IR-level transformations.

#define llvm_unreachable(msg)

Marks that the current location is not supposed to be reachable.

unsigned ID

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

This is an optimization pass for GlobalISel generic memory operations.

CodeGenOptLevel

Code generation optimization level.

DWARFExpression::Operation Op

OutputIt move(R &&Range, OutputIt Out)

Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.

Implement std::hash so that hash_code can be used in STL containers.

A CRTP mix-in to automatically provide informational APIs needed for passes.

A simple container for information about the supported runtime calls.

This represents a list of ValueType's that has been intern'd by a SelectionDAG.
