Lay the groundwork for my upcoming ilist sentinel shrinking patch
by defining a LLVM_COMPACT_SENTINELS symbol to 0 or 1 in config.h. I'm asking for 3 favors: - may an autofoo expert look at this and suggest improvements? - may a cmake expert suggest analogous functionality for config.h? - may somebody with the right autofoo mix regenerate configure? (mine is too new) Thanks! --This line, and those below, will be ignored-- M configure.ac git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78628 91177308-0d34-0410-b5e6-96231b3b80d8
