Stepan Dyatkovskiy cb3a147870 Second patch of patch series that improves MergeFunctions performance time from O(N*N) to ... O(N*log(N)). The idea is to introduce total ordering among functions set. It allows to build binary tree and perform function look-up procedure in O(log(N)) time. This patch description: Introduced total ordering among constants implemented in cmpConstants method. Method performs lexicographical comparison between constants represented as hypothetical numbers of next format: <bitcastability-trait><raw-bit-contents> Please, read cmpConstants declaration comments for more details. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208173 91177308-0d34-0410-b5e6-96231b3b80d8		2014-05-07 09:05:10 +00:00
