Potential infinite loop in MemorySSAUpdater
I understand that changing the starting element to “InsertedPHIs.being() + StartingPHISize” it will be finite but given that InsrtedPHIs is finite.
I have a case where one element(same element is appened to InsertedPHIs) is added to InsertedPHIs every time fixupDefs is invoked. I traced the issue why this was happening.

Potential infinite loop in MemorySSAUpdater
We should only add phis that were newly inserted, not ones that were
already found. There are two cases we will hvae inserted phis:
Part of the recursive call, or right in this function.
The easiest way to differentiate new phis from old ones is whether they
have 0 operands.
I expect the attached will fix it.
If not, please file a bug with reproducible IR.

URGENT: Update to ld.so advisory
Update to KSR[T] Advisory #002
Our advisory contained one serious piece of mis-information. The latest
version of ld.so that we tested (1.9.2) still appeared to be
vulnerable to this overflow.
We strongly recommend that anyone running linux install the patch
distributed with the advisory, or wait for your vendor to release
an updated ld.so package and install that as soon as possible.

[MemorySSA] A question about how to update the MemorySSA when we call RecursivelyDeleteTriviallyDeadInstructions
When we erase a memory access instruction, existing passes using
memory ssa like GVN, NewGVN, GVNHoist and EarlyCSE uses
MemorySSAUpdater to do the update before the instruction is erased.
However, if we call llvm::RecursivelyDeleteTriviallyDeadInstructions
to find out dead instruction recursively and memory access
instructions may be erased inside the recursive process, we need a way
to update

[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: ;

[MemorySSA] inserting or removing memory instructions
In particular, if you want to add support, the right way to know what to
rename is (off the top of my head)
add a flag or something to have renamepass reset all uses it sees (you only
have to change the uses, defs are all linked together and thus already
fixed by the updater). Right now it only does that if they have no
defining access.
Make it skip blocks already in the visited set (the
