Finding all pointers to functions
...is to look at all the global variables:
for (auto &G : M.globals())
for (auto &V : G.operands())
if (auto F = dyn_cast<Function>(V))
Of course, instructions can also refer to functions, both as direct calls
and otherwise:
for (auto &F : M) {
for (auto &I : inst_range(F)) {
for (auto &V : I.operands())
if (auto F = dyn_cast<Function>(V))
But there are other things as well, for example it seems there is something
called a personality function that can be a pointer to another function, so
need to add that
if (F.hasPersonalityFn())
It...

[LLVMdev] DataLayout missing in isDereferenceablePointer()

In test/Analysis/ValueTracking/memory-dereferenceable.ll, just change
byval to dereferenceable(8), and %dparam won't match (see

get it to pass? I tried introducing a target-triple and
target-datalayout, but it didn't help.
