This file implements a class to represent arbitrary precision integral constant values and operations...

#define LLVM_DUMP_METHOD

Mark debug helper function definitions like dump() that should not be stripped from debug builds.

This file contains the declarations for the subclasses of Constant, which represent the different fla...

Module.h This file contains the declarations for the Module class.

#define INITIALIZE_PASS(passName, arg, name, cfg, analysis)

PassT::Result & getResult(IRUnitT &IR, ExtraArgTs... ExtraArgs)

Get the result of an analysis pass for a given IR unit.

Represent the analysis usage information of a pass.

void setPreservesAll()

Set by analyses that do not transform their input at all.

Functions, function parameters, and return types can have attributes to indicate how they should be t...

LLVM_ABI StringRef getValueAsString() const

Return the attribute's value as a string.

bool isValid() const

Return true if the attribute is any kind of attribute.

A Module instance is used to store all the information related to an LLVM module.

LLVM_ABI MDNode * getOperand(unsigned i) const

A set of analyses that are preserved following a run of a transformation pass.

static PreservedAnalyses all()

Construct a special preserved set that preserves all passes.

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

StringRef - Represent a constant reference to a string, i.e.

std::pair< StringRef, StringRef > split(char Separator) const

Split into two substrings around the first occurrence of a separator character.

constexpr bool empty() const

empty - Check if the string is empty.

Triple - Helper class for working with autoconf configuration names.

static LLVM_ABI StringRef getEnvironmentTypeName(EnvironmentType Kind)

Get the canonical name for the Kind environment.

Represents a version number in the form major[.minor[.subminor[.build]]].

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

unsigned ID

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

std::enable_if_t< detail::IsValidPointer< X, Y >::value, X * > extract(Y &&MD)

Extract a Value from Metadata.

This is an optimization pass for GlobalISel generic memory operations.

LLVM_ABI raw_ostream & dbgs()

dbgs() - This returns a reference to a raw_ostream for debugging messages.

FunctionAddr VTableAddr uintptr_t uintptr_t Data

decltype(auto) cast(const From &Val)

cast - Return the argument parameter cast to the specified type.

bool to_integer(StringRef S, N &Num, unsigned Base=0)

Convert the string S to an integer of the specified type using the radix Base. If Base is 0,...

AnalysisManager< Module > ModuleAnalysisManager

Convenience typedef for the Module analysis manager.

A special type used by analysis passes to provide an address that identifies that particular analysis...
