Types ¶

type Attribute ¶

type Attribute uint16

Attribute represents TEXT or DATA flags.

const (
	// Don't profile the marked routine. This flag is deprecated.
	NOPROF Attribute = 1

	// It is ok for the linker to get multiple of these symbols. It will
	// pick one of the duplicates to use.
	DUPOK Attribute = 2

	// Don't insert stack check preamble.
	NOSPLIT Attribute = 4

	// Put this data in a read-only section.
	RODATA Attribute = 8

	// This data contains no pointers.
	NOPTR Attribute = 16

	// This is a wrapper function and should not count as disabling 'recover'.
	WRAPPER Attribute = 32

	// This function uses its incoming context register.
	NEEDCTXT Attribute = 64

	// Allocate a word of thread local storage and store the offset from the
	// thread local base to the thread local storage in this variable.
	TLSBSS Attribute = 256

	// Do not insert instructions to allocate a stack frame for this function.
	// Only valid on functions that declare a frame size of 0.
	NOFRAME Attribute = 512

	// Function can call reflect.Type.Method or reflect.Type.MethodByName.
	REFLECTMETHOD Attribute = 1024

	// Function is the top of the call stack. Call stack unwinders should stop
	// at this function.
	TOPFRAME Attribute = 2048
)

Attribute values defined in textflag.h.

func (Attribute) Asm ¶

func (a Attribute) Asm() string

Asm returns a representation of the attributes in assembly syntax. This may use macros from "textflags.h"; see ContainsTextFlags() to determine if this header is required.

func (Attribute) ContainsTextFlags ¶

func (a Attribute) ContainsTextFlags() bool

ContainsTextFlags returns whether the Asm() representation requires macros in "textflags.h".

func (Attribute) DUPOK ¶

func (a Attribute) DUPOK() bool

DUPOK reports whether the DUPOK flag is set.

func (Attribute) NEEDCTXT ¶

func (a Attribute) NEEDCTXT() bool

NEEDCTXT reports whether the NEEDCTXT flag is set.

func (Attribute) NOFRAME ¶

func (a Attribute) NOFRAME() bool

NOFRAME reports whether the NOFRAME flag is set.

func (Attribute) NOPROF ¶

func (a Attribute) NOPROF() bool

NOPROF reports whether the NOPROF flag is set.

func (Attribute) NOPTR ¶

func (a Attribute) NOPTR() bool

NOPTR reports whether the NOPTR flag is set.

func (Attribute) NOSPLIT ¶

func (a Attribute) NOSPLIT() bool

NOSPLIT reports whether the NOSPLIT flag is set.

func (Attribute) REFLECTMETHOD ¶

func (a Attribute) REFLECTMETHOD() bool

REFLECTMETHOD reports whether the REFLECTMETHOD flag is set.

func (Attribute) RODATA ¶

func (a Attribute) RODATA() bool

RODATA reports whether the RODATA flag is set.

func (Attribute) TLSBSS ¶

func (a Attribute) TLSBSS() bool

TLSBSS reports whether the TLSBSS flag is set.

func (Attribute) TOPFRAME ¶

func (a Attribute) TOPFRAME() bool

TOPFRAME reports whether the TOPFRAME flag is set.

func (Attribute) WRAPPER ¶

func (a Attribute) WRAPPER() bool

WRAPPER reports whether the WRAPPER flag is set.
