Benjamin Kramer 5633d420b2 Sync the __builtin_expects for our 3 quadratically probed hash table implementations. ... This assumes that a) finding the bucket containing the value is LIKELY b) finding an empty bucket is LIKELY c) growing the table is UNLIKELY I also switched the a) and b) cases for SmallPtrSet as we seem to use the set mostly more for insertion than for checking existence. In a simple benchmark consisting of 2^21 insertions of 2^20 unique pointers into a DenseMap or SmallPtrSet a few percent speedup on average, but nothing statistically significant. llvm-svn: 230232		2015-02-23 16:41:36 +00:00
