Author: mramalho Date: Wed Feb 6 19:18:21 2019 New Revision: 353372 URL: http://llvm.org/viewvc/llvm-project?rev=353372&view=rev Log: Moved the whole SMT API to a single file. NFC.
There is no advantage in having them in separate files, I doubt some will ever use them separately. This also makes it easier to move the API to LLVM.
