| | | | | | | | | | | Always fold a shuffle-of-shuffle into a single shuffle when there's only one input vector in the first place. Continue to be more conservative when there's multiple inputs. rdar://13402653 PR15866 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180802 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix for wrong instcombine on vector insert/extractBenjamin Kramer2013-04-111-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to collapse sequences of insertelement/extractelement instructions into single shuffle instructions, there is one specific case where the Instruction Combiner wrongly updates the resulting Mask of shuffle indexes. The problem is in function CollectShuffleElments. If we have a sequence of insert/extract element instructions like the one below: %tmp1 = extractelement <4 x float> %LHS, i32 0 %tmp2 = insertelement <4 x float> %RHS, float %tmp1, i32 1 %tmp3 = extractelement <4 x float> %RHS, i32 2 %tmp4 = insertelement <4 x float> %tmp2, float %tmp3, i32 3 Where: . %RHS will have a mask of [4,5,6,7] . %LHS will have a mask of [0,1,2,3] The Mask of shuffle indexes is wrongly computed to [4,1,6,7] instead of [4,0,6,7]. When analyzing %tmp2 in order to compute the Mask for the resulting shuffle instruction, the algorithm forgets to update the mask index at position 1 with the index associated to the element extracted from %LHS by instruction %tmp1.

* Land the long talked about "type system rewrite" patch. ThisChris Lattner2011-07-091-16/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8
* Change instcombine's getShuffleMask to represent undef with negative values.Bob Wilson2010-10-291-0/+13
| | | | | | | | This code had previously used 2*N, where N is the mask length, to represent undef. That is not safe because the shufflevector operands may have more than N elements -- they don't have to match the result type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117721 91177308-0d34-0410-b5e6-96231b3b80d8
