I think that's suspect too. It's too bad we can't specify separate ABI alignments for v16i/f8, v8i/f16, v4i/f32 and v2i/f64 as we should probably set the ABI alignment to the element alignment. But I guess to be conservative we should set it to 8 bits. Unless I'm misunderstanding the purpose of the ABI alignment. -Dave

The vnot PatFrag uses ImmAllOnesV which should put an OPC_CheckImmAllOnesV in the matcher table. And the matcher table should call ISD::isBuildVectorAllOnes. I believe we use vnot with vXi1 vectors on X86 and I haven't seen any issues. The FIXME you pointed to seems related to a scalar patcher not a vector pattern. In that case the issue is that the immediate matcher for scalars calls

I agree, that doesn't look right. It looks like this is what was intended: Index: lib/CodeGen/SelectionDAG/DAGCombiner.cpp =================================================================== --- lib/CodeGen/SelectionDAG/DAGCombiner.cpp (revision 65000) +++ lib/CodeGen/SelectionDAG/DAGCombiner.cpp (working copy) @@ -4903,9 +4903,9 @@ // resultant store does not need a higher alignment than

...elements, result element zero must come from index 0-3. In isSHUFPMask all we have is the SDNode of the shufflevector index vector. Unfortunately, this tells us nothing about the type of the result vector. If we have two operands, we obviously have a v2i/f64 vector. For eight operands, we have a v8i/f32 vector. But for four operands we could have a v4f/i32 or a v4f/i64. So we can't know the vector element size and thus we can't map shufflevector indices valid ranges for output vector elements. If I change isSHUFPMask to take an extra argument which is the result vector type (or elem...

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
