| | | | | | | | | | | | | | | | | | | | | when something changes, instead of moving forward. This allows us to simplify memset lowering, inserting the memset at the end of the range of stuff we're touching instead of at the start. This, in turn, allows us to make use of the addressing instructions already used in the function instead of inserting our own. For example, we now codegen: %tmp41 = getelementptr [8 x i8]* %ref_idx, i32 0, i32 0 ; <i8*> [#uses=2] call void @llvm.memset.i64( i8* %tmp41, i8 -1, i64 8, i32 1 ) instead of: %tmp20 = getelementptr [8 x i8]* %ref_idx, i32 0, i32 7 ; <i8*> [#uses=1] %ptroffset = getelementptr i8* %tmp20, i64 -7 ; <i8*> [#uses=1] call void @llvm.memset.i64( i8* %ptroffset, i8 -1, i64 8, i32 1 ) llvm-svn: 48940
* make the common case of a single store (which clearly shouldn't be turnedChris Lattner2008-03-291-3/+12

| | | | | | | | | | memsets that initialize "structs of arrays" and other store sequences that are not sequential. This is still only enabled if you pass -form-memset-from-stores. The flag is not heavily tested and I haven't analyzed the perf regressions when -form-memset-from-stores is passed either, but this causes no make check regressions. llvm-svn: 48909

* Avoid creating chain dependencies from CopyToReg nodes to load and storeDan Gohman2008-03-272-56/+73
| | | | | | | | | | | | | | | | | | nodes. This doesn't currently have much impact the generated code, but it does produce simpler-looking SelectionDAGs, and consequently simpler-looking ScheduleDAGs, because there are fewer spurious dependencies. In particular, CopyValueToVirtualRegister now uses the entry node as the input chain dependency for new CopyToReg nodes instead of calling getRoot and depending on the most recent memory reference. Also, rename UnorderedChains to PendingExports and pull it up from being a local variable in SelectionDAGISel::BuildSelectionDAG to being a member variable of SelectionDAGISel, so that it doesn't have to be passed around to all the places that need it. llvm-svn: 48893

* Speed-up the SumOfUnscheduledPredsOfSuccs by introducing a new functionRoman Levenstein2008-03-271-2/+25
| | | | | | | | | | called LimitedSumOfUnscheduledPredsOfSuccs. It terminates the computation after a given treshold is reached. This new function is always faster, but brings real wins only on bigger test-cases. The old function SumOfUnscheduledPredsOfSuccs is left in-place for now and therefore a warning about an unused static function is produced. llvm-svn: 48872
