2008-07-16Test passing of integer parameters for integersDuncan Sands
of all sizes from i1 to i256. The code is not always that great, for example (x86) movw %di, %ax movw %ax, i17_s where the store could be directly from %di. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53677 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-16Redo InstCombiner::visitExtractValueInst. Instead of using the (complicate)Matthijs Kooijman
FindInsertedValue, it now performs a number of simple transformations that should result in the same effect when applied iteratively. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53673 91177308-0d34-0410-b5e6-96231b3b80d8

While this is not a wonderful organizing principle, it does make it easy to find routines, and clear where to insert new ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53672 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-16Don't use ++idx_begin when I actually mean idx_begin + 1, especially since weMatthijs Kooijman
also use *idx_begin in the same expression, giving unpredictable results. This fixes this bug: http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-July/015877.html git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53670 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-16The atomic.cmp.swap promotion logic is wrong: itDuncan Sands
simply does the atomic.cmp.swap on the larger type, which means it blows away whatever is sitting in the bytes just after the memory location, i.e. causes a buffer overflow. This really requires target specific code, which is why LegalizeTypes doesn't try to handle this case generically. The existing (wrong) code in LegalizeDAG will go away automatically once the type legalization code is removed from LegalizeDAG so I'm leaving it there for the moment. Meanwhile, don't test for this feature. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53669 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-15Remove a few tests which no longer hold for deadargelim (since it is nowMatthijs Kooijman
allowed to canonicalize return values). Add a test that checks if return value and function attributes are not removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53612 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-15Add a testcase for the canonicalizations now performed by deadargelim.Matthijs Kooijman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53611 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-15Allow deadargelim to change return types even though now values were dead. ThisMatthijs Kooijman
again canonicalizes {i32} into i32 and {} into void. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53610 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-15Revert r53606. It turns out that explicitely tracking the liveness of theMatthijs Kooijman
return value as a whole in deadargelim is really not needed now that we simply rebuild the old return value and actually prevents some canonicalization from taking place. This revert stops deadargelim from changing {i32} into i32 for now, but I'll fix that next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53609 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-15Make deadargelim a bit less smart, so it doesn't choke on nested structs asMatthijs Kooijman
return values that are still (partially) live. Instead of updating all uses of a call instruction after removing some elements, it now just rebuilds the original struct (With undef gaps where the unused values were) and leaves it to instcombine to clean this up. The added testcase still fails currently, but this is due to instcombine which isn't good enough yet. I will fix that part next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53608 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-15Don't use isa when we can reuse a previous dyn_cast.Matthijs Kooijman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53607 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-15Make DeadArgElim keep liveness of the return value as a whole in addition toMatthijs Kooijman
only the liveness of partial return values (for functions returning a struct). This is more explicit to prevent unwanted changes in the return value. In particular, deadargelim now canonicalizes a function returning {i32} to returning i32 and {} to void, if the struct returned is not used in its entirety, but only the single element is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53606 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-15LegalizeTypes support for promotion of bswap.Duncan Sands
In LegalizeDAG the value is zero-extended to the new type before byte swapping. It doesn't matter how the extension is done since the new bits are shifted off anyway after the swap, so extend by any old rubbish bits. This results in the final assembler for the testcase being one line shorter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53604 91177308-0d34-0410-b5e6-96231b3b80d8
