[MemorySSA] inserting or removing memory instructions
Hi guys,
a question about updating memory SSA:
Is it expected that e.g insertion of MemoryDef doesn't change all dominated
uses?
For example test case CreateLoadsAndStoreUpdater produces:
define void @F(i8*) {
; 1 = MemoryDef(liveOnEntry)
store i8 16, i8* %0
; 4 = MemoryDef(1)
store i8 16, i8* %0
br i1 true, label %2, label %3
; <label>:2: ; preds = %1
; 2 = MemoryDef(4)
store i8 16, i8* %0
br label %4
; <label>...
