2013-02-21DAGCombiner: Make the post-legalize vector op optimization more aggressive.Benjamin Kramer
A legal BUILD_VECTOR goes in and gets constant folded into another legal BUILD_VECTOR so we don't lose any legality here. The problematic PPC optimization that made this check necessary was fixed recently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175759 91177308-0d34-0410-b5e6-96231b3b80d8

The constructs %hi() and %lo() represent the high and low 16 bits of the address. Because the 16 bit offset field of an LW instruction is interpreted as signed, if bit 15 of the low part is 1 then the low part will act as a negative and 1 needs to be added to the high part.

2013-02-21PPCDAGToDAGISel::PostprocessISelDAG()Bill Schmidt
This patch implements the PPCDAGToDAGISel::PostprocessISelDAG virtual method to perform post-selection peephole optimizations on the DAG representation. One optimization is implemented here: folds to clean up complex addressing expressions for thread-local storage and medium code model. It will also be useful for large code model sequences when those are added later. I originally thought about doing this on the MI representation prior to register assignment, but it's difficult to do effective global dead code elimination at that point. DCE is trivial on the DAG representation. A typical example of a candidate code sequence in assembly: addis 3, 2, globalvar@toc@ha addi 3, 3, globalvar@toc@l lwz 5, 0(3) When the final instruction is a load or store with an immediate offset of zero, the offset from the add-immediate can replace the zero, provided the relocation information is carried along: addis 3, 2, globalvar@toc@ha lwz 5, globalvar@toc@l(3) Since the addi can in general have multiple uses, we need to only delete the instruction when the last use is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175697 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-20Copy single reaching defs directly into the LiveInterval.Jakob Stoklund Olesen
When findReachingDefs() finds that only one value can reach the basic block, just copy the work list of visited blocks directly into the live interval. Sort the block list and use a LiveRangeUpdater to make the bulk add fast. When multiple reaching defs are found, transfer the work list to the updateSSA() work list as before. Also use LiveRangeUpdater in updateLiveIns() following updateSSA(). This makes live interval analysis more than 3x faster on one huge test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175685 91177308-0d34-0410-b5e6-96231b3b80d8
