System memory allocation functions, which are identified at the IR level by the noalias attribute on the return value, must return a pointer into a memory region disjoint from any other memory accessible to the caller. We can use this property to simplify pointer comparisons between allocated memory and local stack addresses and the addresses of global variables. Neither the stack nor global variables can overlap with the region used by the memory allocator. Fixes PR21556. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223093 91177308-0d34-0410-b5e6-96231b3b80d8 |
