std::string Name
This file implements the StringSwitch template, which mimics a switch() statement whose cases are str...
StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50
A switch()-like statement whose cases are string literals.
Definition: StringSwitch.h:44
R Default(T Value)
Definition: StringSwitch.h:182
Triple - Helper class for working with autoconf configuration names.
Definition: Triple.h:44
This class implements an extremely fast bulk output stream that can only output to a stream.
Definition: raw_ostream.h:52
#define llvm_unreachable(msg)
Marks that the current location is not supposed to be reachable.
Architecture getArchitectureFromName(StringRef Name)
Convert a name to an architecture slice.
StringRef getArchitectureName(Architecture Arch)
Convert an architecture slice to a string.
std::pair< uint32_t, uint32_t > getCPUTypeFromArchitecture(Architecture Arch)
Convert an architecture slice to a CPU Type and Subtype pair.
bool is64Bit(Architecture)
Check if architecture is 64 bit.
Architecture
Defines the architecture slices that are supported by Text-based Stub files.
Definition: Architecture.h:27
raw_ostream & operator<<(raw_ostream &OS, Architecture Arch)
Architecture mapToArchitecture(const llvm::Triple &Target)
Convert a target to an architecture slice.
Architecture getArchitectureFromCpuType(uint32_t CPUType, uint32_t CPUSubType)
Convert a CPU Type and Subtype pair to an architecture slice.
This is an optimization pass for GlobalISel generic memory operations.
