15 years agoStep #1 to giving Callgraph some sane invariants. The problems with callgraph
Chris Lattner [Mon, 31 Aug 2009 07:23:46 +0000 (07:23 +0000)]
Step #1 to giving Callgraph some sane invariants.  The problems with callgraph
stem from the fact that we have two types of passes that need to update it:

1. callgraphscc and module passes that are explicitly aware of it
2. Functionpasses (and loop passes etc) that are interlaced with CGSCC passes
   by the CGSCC Passmgr.

In the case of #1, we can reasonably expect the passes to update the call
graph just like any analysis.  However, functionpasses are not and generally
should not be CG aware.  This has caused us no end of problems, so this takes
a new approach.  Logically, the CGSCC Pass manager can rescan every function
after it runs a function pass over it to see if the functionpass made any
updates to the IR that affect the callgraph.  This allows it to catch new calls
introduced by the functionpass.

In practice, doing this would be slow.  This implementation keeps track of
whether or not the current scc is dirtied by a function pass, and, if so,
delays updating the callgraph until it is actually needed again.  This was
we avoid extraneous rescans, but we still have good invariants when the
callgraph is needed.

Step #2 of the "give Callgraph some sane invariants" is to change CallGraphNode
to use a CallBackVH for the callsite entry of the CallGraphNode.  This way
we can immediately remove entries from the callgraph when a FunctionPass is
active instead of having dangling pointers.  The current pass tries to tolerate
these dangling pointers, but it is just an evil hack.

This is related to PR3601/4835/4029.  This also reverts r80541, a hack working
around the sad lack of invariants.

simplify some code by making the SCCNodes set contain Function*'s
instead of CallGraphNode*'s.  This also papers over a callgraph
problem where a pass (in this case, MemCpyOpt) introduces a new
function into the module (llvm.memset.i64) but doesn't add it to
the call graph (nor should it, since it is a function pass).

While it might be a good idea for MemCpyOpt to not synthesize
functions in a runOnFunction(), there is no need for FunctionAttrs
to be boneheaded, so fix it there.  This fixes an assertion building
176.gcc.

Fix PR4834, a tricky case where the inliner would resolve an
indirect function pointer, inline it, then go to delete the body.
The problem is that the callgraph had other references to the function,
though the inliner had no way to know it, so we got a dangling pointer
and an invalid iterator out of the deal.

The fix to this is pretty simple: stop the inliner from deleting the
function by knowing that there are references to it.  Do this by making
CallGraphNodes contain a refcount.  This requires moving deletion of
available_externally functions to the module-level cleanup sweep where
it belongs.

15 years agoFix some nasty callgraph dangling pointer problems in
Chris Lattner [Mon, 31 Aug 2009 00:19:58 +0000 (00:19 +0000)]
Fix some nasty callgraph dangling pointer problems in
argpromotion and structretpromote.  Basically, when replacing
a function, they used the 'changeFunction' api which changes
the entry in the function map (and steals/reuses the callgraph
node).

This has some interesting effects: first, the problem is that it doesn't
update the "callee" edges in any callees of the function in the call graph.
Second, this covers for a major problem in all the CGSCC pass stuff, which
is that it is completely broken when functions are deleted if they *don't*
reuse a CGN.  (there is a cute little fixme about this though :).

This patch changes the protocol that CGSCC passes must obey: now the CGSCC
pass manager copies the SCC and preincrements its iterator to avoid passes
invalidating it.  This allows CGSCC passes to mutate the current SCC.  However
multiple passes may be run on that SCC, so if passes do this, they are now
required to *update* the SCC to be current when they return.

Other less interesting parts of this patch are that it makes passes update
the CG more directly, eliminates changeFunction, and requires clients of
replaceCallSite to specify the new callee CGN if they are changing it.

inline the trivial AddToWorkList/RemoveFromWorkList methods
into their callers.  simplify ReplaceInstUsesWith.  Make
EraseInstFromFunction only add operands to the worklist if
there aren't too many of them (this was a scalability win
for crazy programs that was only infrequently enforced).
Switch more code to using EraseInstFromFunction instead of
duplicating it inline.  Change some fcmp/icmp optimizations
to modify fcmp/icmp in place instead of creating a new one
and deleting the old one just to change the predicate.
