2012-04-14Rename "fpaccuracy" metadata to the more generic "fpmath". That's because I'mDuncan Sands
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

2012-04-14Fix an error in BBVectorize important for vectorizing pointer types.Hal Finkel
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

2012-04-13misched: Added CanHandleTerminators.Andrew Trick
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

2012-04-13By default, use Early-CSE instead of GVN for vectorization cleanup.Hal Finkel
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

2012-04-13Silence various build warnings from Hexagon backend that show up in release ↵Craig Topper
builds. Mostly converting 'assert(0)' to 'llvm_unreachable' to silence warnings about missing returns.

2012-04-12Disable Hexagon test temporarily.Sirish Pande
There is an assert at line 558 in ScheduleDAGInstrs::buildSchedGraph(AliasAnalysis *AA). This assert needs to addressed for post RA scheduler. Until that assert is addressed, any passes that uses post ra scheduler will fail. So, I am temporarily disabling the hexagon tests until that fix is in. The assert is as follows: assert(!MI->isTerminator() && !MI->isLabel() && "Cannot schedule terminators or labels!"); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154617 91177308-0d34-0410-b5e6-96231b3b80d8
