// InstructionCombining - Combine instructions to form fewer, simple
|
|
// instructions. This pass does not modify the CFG, and has a tendancy to
|
|
// make instructions dead, so a subsequent DCE pass is useful.
|
|
//
|
|
// This pass combines things like:
|
|
// %Y = add int 1, %X
|
|
// %Z = add int 1, %Y
|
|
// into:
|
|
// %Z = add int 2, %X
|
