Nuno Lopes 9969458b16 teach instcombine to remove allocated buffers even if there are stores, memcpy/memmove/memset, and objectsize users. ... This means we can do cheap DSE for heap memory. Nothing is done if the pointer excapes or has a load. The churn in the tests is mostly due to objectsize, since we want to make sure we don't delete the malloc call before evaluating the objectsize (otherwise it becomes -1/0) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159876 91177308-0d34-0410-b5e6-96231b3b80d8		2012-07-06 23:09:25 +00:00
