Functions

func Info

func Info(fnsym *obj.LSym, infosym *obj.LSym, curfn interface{}) ([]dwarf.Scope, dwarf.InlCalls)

func RecordFlags

func RecordFlags(flags ...string)

RecordFlags records the specified command-line flags to be placed in the DWARF info.

func RecordPackageName

func RecordPackageName()

RecordPackageName records the name of the package being compiled, so that the linker can save it in the compile unit's DIE.
