ConstantArrays constructed during linking can cause quadratic memory explosion. An example is the ConstantArrays constructed when linking in GlobalVariables with appending linkage. Releasing all unused constants can cause a 20% LTO compile-time slowdown for a large application. So this commit releases unused ConstantArrays only. rdar://19040716. It reduces memory footprint from 20+G to 6+G. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226592 91177308-0d34-0410-b5e6-96231b3b80d8 |
