... but those patches simply disable all conditionally-executed instructions,
which is no good for mainline. What is needed is a new CC mode, as discussed in

It looks like the testcase in comment #2 should be fixed by SSUPRE? We have

if ()
foo();
where foo() is an implicit store to *p. Still store sinking should be
applied

this is what we optimize it to:

Well it depends really. As on some targets it has a CFG based ||/
