2013-02-27LoopVectorize: Vectorize math builtin calls.Benjamin Kramer
This properly asks TargetLibraryInfo if a call is available and if it is, it can be translated into the corresponding LLVM builtin. We don't vectorize sqrt() yet because I'm not sure about the semantics for negative numbers. The other intrinsic should be exact equivalents to the libm functions.

2013-02-27For each function that we optimize we initialize a new list of lib ↵Nadav Rotem
functions. For each function name we malloc memory. This patch changes the Libcall map to use BumpPtrAllocator. Now we malloc only once. This speeds up instcombine by a few % on a large c++ program. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176170 91177308-0d34-0410-b5e6-96231b3b80d8

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
