◆ SaveStatsMode

◆ createTargetMachineForTriple()

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()

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.

◆ MaybeEnableStatistics()

void llvm::codegen::MaybeEnableStatistics ( )

◆ MaybeSaveStatistics()

Conditionally saves the collected LLVM statistics to the received output file, based on the value of the flag.

Should be called after the tool run, and must follow a call to MaybeEnableStatistics() to actually have data to write.
