2013-03-10Remove unneeded #includes. Use forward declarations instead.Jakub Staszak
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176783 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-03Sort the #include lines for the include/... tree with the script.Chandler Carruth
AKA: Recompile *ALL* the source code! This one went much better. No manual edits here. I spot-checked for silliness and grep-checked for really broken edits and everything seemed good. It all still compiles. Yell if you see something that looks goofy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169133 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-08Give CaptureTracker::shouldExplore a base implementation. Most users want to doNick Lewycky
the same thing. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165435 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-17Move includes to the .cpp file.Jakub Staszak
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148342 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-28Change CaptureTracking to pass a Use* instead of a Value* when a value isNick Lewycky
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147327 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-21Add virtual destructor. Whoops!Nick Lewycky

2011-11-20Less template, more virtual! Refactoring suggested by Chris in code review.Nick Lewycky
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145014 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-20Refactor code to use new attribute getters on CallSite for NoCapture and ByVal.Nick Lewycky
Suggested in code review by Eli. That code in InstCombine looks kinda suspicious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145013 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-14Refactor capture tracking (which already had a couple flags for whether returnsNick Lewycky
and stores capture) to permit the caller to see each capture point and decide whether to continue looking. Use this inside memdep to do an analysis that basicaa won't do. This lets us solve another devirtualization case, fixing PR8908! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144580 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-19Extend CaptureTracking to indicate when a value is never stored, evenDan Gohman
if it is not ultimately captured. Teach BasicAliasAnalysis that a local object address which does not escape and is never stored does not alias with a value resulting from a load. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89398 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-18BasicAliasAnalysis and FunctionAttrs were bothDuncan Sands
doing very similar pointer capture analysis. Factor out the common logic. The new version is from FunctionAttrs since it does a better job than the version in BasicAliasAnalysis git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62461 91177308-0d34-0410-b5e6-96231b3b80d8
