2013-02-27IR: Don't constant fold GEP bitcasts between different address spacesMeador Inge
PR15262 reported a bug where the following instruction: i8 getelementptr inbounds i8* bitcast ([4 x i8] addrspace(12)* @buf to i8*), i32 2 was getting folded into: addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @buf, i32 0, i32 2) This caused instcombine to crash because the original instruction and the folded instruction have different types. The issue was fixed by disallowing bitcasts between different address spaces to be folded away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176156 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-25Fix the root cause of PR15348 by correctly handling alignment 0 onChandler Carruth
memory intrinsics in the SDAG builder. When alignment is zero, the lang ref says that *no* alignment assumptions can be made. This is the exact opposite of the internal API contracts of the DAG where alignment 0 indicates that the alignment can be made to be anything desired. There is another, more explicit alignment that is better suited for the role of "no alignment at all": an alignment of 1. Map the intrinsic alignment to this early so that we don't end up generating aligned DAGs. It is really terrifying that we've never seen this before, but we suddenly started generating a large number of alignment 0 memcpys due to the new code to do memcpy-based copying of POD class members. That patch contains a bug that rounds bitfield alignments down when they are the first field. This can in turn produce zero alignments. This fixes weird crashes I've seen in library users of LLVM on 32-bit hosts, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176022 91177308-0d34-0410-b5e6-96231b3b80d8
