2009-10-25Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces.Nick Lewycky
Chris claims we should never have visibility_hidden inside any .cpp file but that's still not true even after this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85042 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-15add a new CallGraphNode::replaceCallEdge method and use it fromChris Lattner
argpromote to avoid invalidating an iterator. This fixes PR4977. All clang tests now pass with expensive checking (on my system at least). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81843 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-31Fix some nasty callgraph dangling pointer problems in Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80527 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-30Switch obvious clients to Twine instead of utostr (when they were already usingDaniel Dunbar
a Twine, e.g., for names). - I am a little ambivalent about this; we don't want the string conversion of utostr, but using overload '+' mixed with string and integer arguments is sketchy. On the other hand, this particular usage is something of an idiom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77579 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-25More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar
- Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77019 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-29Restructure ArgumentPromotion a bit. Instead of just having a single booleanMatthijs Kooijman
that says "unconditional loads from this argument are safe", we now keep track of the safety per set of indices from which loads happen. This prevents ArgPromotion from promoting loads that aren't really valid. As an added effect, this will now disregard the the type of the indices passed to a GEP, so "load GEP %A, i32 1" and "load GEP %A, i64 1" will result in a single argument, not two. This fixes PR2598, for which a testcase has been added as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54159 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-26Factor code to copy global value attributes likeDuncan Sands
the section or the visibility from one global value to another: copyAttributesFrom. This is particularly useful for duplicating functions: previously this was done by explicitly copying each attribute in turn at each place where a new function was created out of an old one, with the result that obscure attributes were regularly forgotten (like the collector or the section). Hopefully now everything is uniform and nothing is forgotten. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51567 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-12Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner
1. There is now a "PAListPtr" class, which is a smart pointer around the underlying uniqued parameter attribute list object, and manages its refcount. It is now impossible to mess up the refcount. 2. PAListPtr is now the main interface to the underlying object, and the underlying object is now completely opaque. 3. Implementation details like SmallVector and FoldingSet are now no longer part of the interface. 4. You can create a PAListPtr with an arbitrary sequence of ParamAttrsWithIndex's, no need to make a SmallVector of a specific size (you can just use an array or scalar or vector if you wish). 5. All the client code that had to check for a null pointer before dereferencing the pointer is simplified to just access the PAListPtr directly. 6. The interfaces for adding attrs to a list and removing them is a bit simpler. Phase #2 will rename some stuff (e.g. PAListPtr) and do other less invasive changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48289 91177308-0d34-0410-b5e6-96231b3b80d8
