Constructor & Destructor Documentation

◆ sp_instr_hreturn()

sp_instr_hreturn::sp_instr_hreturn	(	uint	ip,
		sp_pcontext *	ctx
	)

Member Function Documentation

◆ execute()

bool sp_instr_hreturn::execute	(	THD *	thd,
		uint *	nextp
	)

overridevirtual

Execute this instruction.

Parameters

	thd	Thread context
[out]	nextp	index of the next instruction to execute. (For most instructions this will be the instruction following this one). Note that this parameter is undefined in case of errors, use get_cont_dest() to find the continuation instruction for CONTINUE error handlers.

Returns: Error status.

Reimplemented from sp_instr_jump.

◆ get_psi_info()

PSI_statement_info * sp_instr_hreturn::get_psi_info ( )

inlineoverridevirtual

Reimplemented from sp_instr_jump.

◆ opt_mark()

uint sp_instr_hreturn::opt_mark	(	sp_head *	,
		List< sp_instr > *	leads
	)

overridevirtual

Mark this instruction as reachable during optimization and return the index to the next instruction.

Jump instruction will add their destination to the leads list.

Reimplemented from sp_instr_jump.

◆ opt_shortcut_jump()

uint sp_instr_hreturn::opt_shortcut_jump	(	sp_head *	,
		sp_instr *
	)

inlineoverridevirtual

Override sp_instr_jump's shortcut; we stop here.

Reimplemented from sp_instr_jump.

◆ print()

void sp_instr_hreturn::print	(	const THD *	thd,
		String *	str
	)

overridevirtual

Reimplemented from sp_instr_jump.

◆ type()

enum Instr_type sp_instr_hreturn::type ( )

inlineoverridevirtual

Get the instruction type of this instruction.

Returns: the instruction type

Reimplemented from sp_instr_jump.
