bool sp_instr_hreturn::execute	(	THD *	thd,
		uint *	nextp
	)		`[virtual]`

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.

uint sp_instr_hreturn::opt_mark	(	sp_head *	sp,
		List< sp_instr > *	leads
	)		`[virtual]`

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.

virtual uint sp_instr_hreturn::opt_shortcut_jump	(	sp_head *	sp,
		sp_instr *	start
	)		`[inline, virtual]`

Override sp_instr_jump's shortcut; we stop here.

Reimplemented from sp_instr_jump.
