We switch the order of offset and field type to make TBAAStructType node
(name, parent node, offset) similar to scalar TBAA node (name, parent node).
TypeIsImmutable is added to TBAAStructTag node.

Aliasing rules for struct-path aware TBAA.2013-04-11T23:24:18ZManman Renmren@apple.com2013-04-11T23:24:18Zurn:sha1:4df1854f263180fcd04cee3347990afe34749a89
Added PathAliases to check if two struct-path tags can alias.
Added command line option -struct-path-tbaa.

Support in AAEvaluator to print alias queries of loads/stores with TBAA tags.2013-03-22T22:34:41ZManman Renmren@apple.com2013-03-22T22:34:41Zurn:sha1:a2e3834d1644889484ef3a8a94189b7369e3eaf9
Add "evaluate-tbaa" to print alias queries of loads/stores. Alias queries
between pointers do not include TBAA tags.
Add testing case for "placement new". TBAA currently says NoAlias.

Use references to attribute groups on the call/invoke instructions.2013-02-22T09:09:42ZBill Wendlingisanbard@gmail.com2013-02-22T09:09:42Zurn:sha1:351b7a10e2560a835759748c58da09e53207b39d
Listing all of the attributes for the callee of a call/invoke instruction is way
too much and makes the IR unreadable. Use references to attributes instead.

Modify the LLVM assembly output so that it uses references to represent function attributes.2013-02-20T07:21:42ZBill Wendlingisanbard@gmail.com2013-02-20T07:21:42Zurn:sha1:7ab6c76ad1cbf36284ca5b6bd5ee33c625fe3e60
This makes the LLVM assembly look better. E.g.:
define void @foo() #0 { ret void }
attributes #0 = { nounwind noinline ssp }

Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed.2012-02-16T06:28:33ZEli Benderskyeli.bendersky@intel.com2012-02-16T06:28:33Zurn:sha1:0f0c411079cd21bb3a81a1b70bf8c67539a16c22
Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches.

Change CaptureTracking to pass a Use* instead of a Value* when a value is2011-12-28T23:24:21ZNick Lewyckynicholas@mxc.ca2011-12-28T23:24:21Zurn:sha1:b48a18903a5769f0ecb295db069252576b1388b0
captured. This allows the tracker to look at the specific use, which may be
especially interesting for function calls.
Use this to fix 'nocapture' deduction in FunctionAttrs. The existing one does
not iterate until a fixpoint and does not guarantee that it produces the same
result regardless of iteration order. The new implementation builds up a graph
of how arguments are passed from function to function, and uses a bottom-up walk
on the argument-SCCs to assign nocapture. This gets us nocapture more often, and
does so rather efficiently and independent of iteration order.
