A collection of metadata nodes that might be associated with a memory access used by the alias-analysis infrastructure.

SlotIndex - An opaque wrapper around machine indexes.

Properties which a MachineFunction may have at a given point in time. Each of these has checking code in the MachineVerifier, and passes can require t

A wrapper around std::string which contains a source range that's being set during parsing.

Wrapper class representing virtual and physical registers. Should be passed by value.

Struct that holds a reference to a particular GUID in a global value summary.

Wrapper class for IR location info (IR ordering and DebugLoc) to be passed into SDNode creation functions. When an SDNode is created from the DAGBuild

A Counter is an abstract value that describes how to compute the execution count for a region of code using the collected profile count data.

A Counter mapping region associates a source range with a specific counter.

Represents the relative location of an instruction. Instruction locations are specified by the line offset from the beginning of the function (marked

Iterator over Functions, optionally filtered to a single file.

An iterator for DICompileUnits that skips those marked NoDebug.

===----------------------------------------------------------------------===// \class This class holds the attributes for a function, its return value

Result of a LiveRange query. This class hides the implementation details of live ranges, and it should be used as the primary interface for examining

This class contains a discriminated union of information about pointers in memory operands, relating them back to LLVM IR or to virtual locations (suc

Matcher for a specific constant value.

Either constexpr if or renaming ConstantFP::getValueAPF to ConstantFP::getValue is needed to do it via single template function for both apint/apfloat

A Counter expression is a value that represents an arithmetic operation with two counters.

A file format agnostic iterator over coverage mapping data.

===--------------------------------------------------------------------===// Dwarf abbreviation data, describes one attribute of a Dwarf abbreviation.

Identifies a unique instance of a variable. Storage for identifying a potentially inlined instance of a variable, or a fragment thereof. This guarant

Extended Value Type. Capable of holding value types which are not native for any processor (such as the i12345 type), as well as the types an MVT can

A file format agnostic iterator over profiling data.

MachineOperand class - Representation of each machine instruction operand. This class isn't a POD type because it has a private constructor, but its

Pass for printing a Function as LLVM's text IR assembly. Note: This pass is for use with the new pass manager. Use the create...Pass functions above

Thin wrapper around "int" used to store reaching definitions, using an encoding that makes it compatible with TinyPtrVector. The 0th LSB is forced zer

These are IR-level optimization flags that may be propagated to SDNodes. TODO: This data structure should be shared by the IR optimizer and the the ba

Sample context for FunctionSamples. It consists of the calling context, the function name and context state. Internally sample context is represented

Create a verifier pass. Check a module or function for validity. This is essentially a pass wrapped around the above verifyFunction and verifyModule

A nullable Value handle that is nullable. This is a value handle that points to a value, and nulls itself out if that value is deleted.

===----------------------------------------------------------------------===// \class Functions, function parameters, and return types can have attrib

Serializable representation of CallSiteInfo.

ConstMIBundleOperands - Iterate over all operands in a const bundle of machine instructions.
