Types

type DebugFlag

type DebugFlag struct {
	// contains filtered or unexported fields
}

func NewDebugFlag

func NewDebugFlag(debug interface{}, debugSSA DebugSSA) *DebugFlag

NewDebugFlag constructs a DebugFlag for the fields of debug, which must be a pointer to a struct.

Each field of *debug is a different value, named for the lower-case of the field name. Each field must be an int or string and must have a `help` struct tag. There may be an "Any bool" field, which will be set if any debug flags are set.

The returned flag takes a comma-separated list of settings. Each setting is name=value; for ints, name is short for name=1.

If debugSSA is non-nil, any debug flags of the form ssa/... will be passed to debugSSA for processing.

func (*DebugFlag) Set

func (f *DebugFlag) Set(debugstr string) error

func (*DebugFlag) String

func (f *DebugFlag) String() string

type DebugSSA

type DebugSSA func(phase, flag string, val int, valString string) string

A DebugSSA function is called to set a -d ssa/... option. If nil, those options are reported as invalid options. If DebugSSA returns a non-empty string, that text is reported as a compiler error. If phase is "help", it should print usage information and terminate the process.
