<div>It would require updating defining accesses in the walker
(otherwise, it will slow down every query that asks about a

caching something the size of memoryssa ;)).</div>

I've collected some compile time stats when enabling
MemorySSA EarlyCSE just for the EarlyCSE pass added at the
beginning of addFunctionSimplificationPasse<wbr>s at O2 and
higher.<br>
There were 8 benchmarks in the llvm test-suite whose compile
time increased by more than 1%. The biggest increase was in
consumer-typeset. Drilling down a bit, the MemorySSA
construction time for compiling the z44.c input to this
benchmark is reported as 2% of runtime.<br>
