Member Function Documentation

virtual void sp_instr_hpush_jump::backpatch ( uint  dest )

inlinevirtual

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.

Definition at line 1084 of file sp_instr.h.

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.

Definition at line 1282 of file sp_instr.cc.

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.

Definition at line 1315 of file sp_instr.cc.

Here is the call graph for this function:

virtual uint sp_instr_hpush_jump::opt_shortcut_jump ( sp_head *  sp, sp_instr *  start  )

inlinevirtual

Override sp_instr_jump's shortcut; we stop here.

Reimplemented from sp_instr_jump.

Definition at line 1077 of file sp_instr.h.
