Function Documentation

◆ createTargetMachineForTriple()

Expected< std::unique_ptr< TargetMachine > > llvm::codegen::createTargetMachineForTriple ( StringRef  TargetTriple,
CodeGenOptLevel  OptLevel = CodeGenOptLevel::Default 
)

Creates a TargetMachine instance with the options defined on the command line.

This can be used for tools that do not need further customization of the TargetOptions.

◆ InitTargetOptionsFromCodeGenFlags()

TargetOptions llvm::codegen::InitTargetOptionsFromCodeGenFlags ( const llvm::Triple TheTriple)

Common utility function tightly tied to the options listed here.

Initializes a TargetOptions object with CodeGen flags and returns it. TheTriple is used to determine the default value for options if options are not explicitly specified. If those triple dependant options value do not have effect for your component, a default Triple() could be passed in.
