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!
