2009-10-08remove LoopVR pass. According to Nick:Chris Lattner
"LoopVR's logic was copied into ScalarEvolution::getUnsignedRange and ::getSignedRange. Please delete LoopVR." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83531 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Change Pass::print to take a raw ostream instead of std::ostream,Chris Lattner
update all code that this affects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79830 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-18Replace intersectWith with maximalIntersectWith. The latter guarantees thatNick Lewycky
all values belonging to the intersection will belong to the resulting range. The former was inconsistent about that point (either way is fine, just pick one.) This is part of PR4545. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76289 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-24Rename ScalarEvolution's getIterationCount to getBackedgeTakenCount,Dan Gohman
to more accurately describe what it does. Expand its doxygen comment to describe what the backedge-taken count is and how it differs from the actual iteration count of the loop. Adjust names and comments in associated code accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65382 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27Avoid crashing if instruction is not part of a loop.Torok Edwin
If it is not part of a loop it is obviously invariant wrt to all loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58240 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Switch the asmprinter (.ll) and all the stuff it requires over toChris Lattner
use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55263 91177308-0d34-0410-b5e6-96231b3b80d8
