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.

destdestination instruction pointer.

Reimplemented from sp_instr_jump.

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

Execute this instruction

thdThread context
[out]nextpindex 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.
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.
