Duncan P. N. Exon Smith d908c6425f IR: Use DenseSet instead of DenseMap for ConstantUniqueMap; NFC ... Use a DenseSet instead of a DenseMap for constants in LLVMContextImpl. Last time I looked at this was some time before r223588, when DenseSet<V> had no advantage over DenseMap<V,char>. After r223588, there's a 50% memory savings. This is all mechanical. There were little bits of missing API from DenseSet so I added the trivial implementations: - iterator::operator++(int) - template <class LookupKeyT> insert_as(ValueTy, LookupKeyT) There should be no functionality change, just reduced memory consumption (this wasn't on a profile or anything; just a cleanup I stumbled on). llvm-svn: 265577		2016-04-06 17:56:08 +00:00
