virtual void sp_instr_hpush_jump::backpatch

(

uint

dest

)

[inline, virtual]

Update all instruction with the given label in the backpatch list to the specified instruction pointer.

Parameters:

dest	destination instruction pointer.

Reimplemented from sp_instr_jump.

bool sp_instr_hpush_jump::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_hpush_jump::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_hpush_jump::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.
