* Rename "fpaccuracy" metadata to the more generic "fpmath". That's because I'mDuncan Sands2012-04-146-47/+47
| | | | | | | | | | thinking of generalizing it to be able to specify other freedoms beyond accuracy (such as that NaN's don't have to be respected). I'd like the 3.1 release (the first one with this metadata) to have the more generic name already rather than having to auto-upgrade it in 3.2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154744 91177308-0d34-0410-b5e6-96231b3b80d8
* Make StringMap's copy ctor non-explicit.Benjamin Kramer2012-04-141-1/+1

* Fix an error in BBVectorize important for vectorizing pointer types.Hal Finkel2012-04-142-0/+54
| | | | | | | | | | When vectorizing pointer types it is important to realize that potential pairs cannot be connected via the address pointer argument of a load or store. This is because even after vectorization, the address is still a scalar because the address of the higher half of the pair is implicit from the address of the lower half (it need not be, and should not be, explicitly computed). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154735 91177308-0d34-0410-b5e6-96231b3b80d8

* misched: Added CanHandleTerminators.Andrew Trick2012-04-132-3/+10
| | | | | | | | | This is a special flag for targets that really want their block terminators in the DAG. The default scheduler cannot handle this correctly, so it becomes the specialized scheduler's responsibility to schedule terminators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154712 91177308-0d34-0410-b5e6-96231b3b80d8

* By default, use Early-CSE instead of GVN for vectorization cleanup.Hal Finkel2012-04-131-2/+9
| | | | | | | | | | As has been suggested by Duncan and others, Early-CSE and GVN should do similar redundancy elimination, but Early-CSE is much less expensive. Most of my autovectorization benchmarks show a performance regresion, but all of these are < 0.1%, and so I think that it is still worth using the less expensive pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154673 91177308-0d34-0410-b5e6-96231b3b80d8
