2008-09-01Turn this legalize types test on.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55605 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-01Add a small pass that sets the readnone/readonlyDuncan Sands
attributes on functions, based on the result of alias analysis. It's not hardwired to use GlobalsModRef even though this is the only (AFAIK) alias analysis that results in this pass actually doing something. Enable as follows: opt ... -globalsmodref-aa -markmodref ... Advantages of this pass: (1) records the result of globalsmodref in the bitcode, meaning it is available for use by later passes (currently the pass manager isn't smart enough to magically make an advanced alias analysis available to all later passes), which may expose more optimization opportunities; (2) hopefully speeds up compilation when code is optimized twice, for example when a file is compiled to bitcode, then later LTO is done on it: marking functions readonly/readnone when producing the initial bitcode should speed up alias analysis during LTO; (3) good for discovering that globalsmodref doesn't work very well :) Not currently turned on by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55604 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-31Revert the "XFAIL" for the rotate_ops.ll testcase. Instead, mark ISD::ROTRBill Wendling
instructions in CellSPU as "Expand" so that they won't be generated. I added a "FIXME" so that this hack can be addressed and reverted once ISD::ROTR is supported in the .td files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55582 91177308-0d34-0410-b5e6-96231b3b80d8

Dale, Could you please review this? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55581 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-31CellSPU doesn't appear to support fully the "ISD::ROTR" operation. The DAGBill Wendling
combiner can now generate ROTR if the backend says that it can handle it. Cell SPU says this, but gets an error from code gen saying that it can't select ROTR. I'm xfailing this test until this can be fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55579 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-31- Fix comment so that it describes how the code really works:Bill Wendling
// fold (or (shl x, (*ext y)), (srl x, (*ext (sub 32, y)))) -> // (rotl x, y) // fold (or (shl x, (*ext y)), (srl x, (*ext (sub 32, y)))) -> // (rotr x, (sub 32, y)) Example: (x == 0xDEADBEEF and y == 4) (x << 4) | (x >> 28) => 0xEADBEEF0 | 0x0000000D => 0xEADBEEFD (rotl x, 4) => 0xEADBEEFD (rotr x, 28) => 0xEADBEEFD - Fix comment and code for second version. It wasn't using the rot* propertly. // fold (or (shl x, (*ext (sub 32, y))), (srl x, (*ext r))) -> // (rotr x, y) // fold (or (shl x, (*ext (sub 32, y))), (srl x, (*ext r))) -> // (rotl x, (sub 32, y)) (x << 28) | (x >> 4) => 0xD0000000 | 0x0DEADBEE => 0xDDEADBEE (rotl x, 4) => 0xEADBEEFD (rotr x, 28) => (0xEADBEEFD) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55575 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-30Fix an issue where a use might be selected before a def, and then we didn't ↵Owen Anderson
respect the pre-chosen vreg assignment when selecting the def. This is the naive solution to the problem: insert a copy to the pre-chosen vreg. Other solutions might be preferable, such as: 1) Passing the dest reg into FastEmit_. However, this would require the higher level code to know about reg classes, which they don't currently. 2) Selecting blocks in reverse postorder. This has some compile time cost for computing the order, and we'd need to measure its impact. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55555 91177308-0d34-0410-b5e6-96231b3b80d8
