Alex Zinenko	6aae7b2e9a	CMake build: force-link SDBM lib into SDBM unit tests ... Otherwise, GCC < 7 does not link in the dialect registration, fails to look up the dialect in the context and cannot construct SDBM objects. -- PiperOrigin-RevId: 249259758	2019-06-01 19:54:53 -07:00
Alex Zinenko	3b500c694d	Move SDBM uniquer into the SDBM dialect ... MLIRContext does not have to be aware of the SDBM unique data structures directly. Move the SDBM storage uniquer from MLIRContext to the SDBM dialect instance. Expressions that previously required a context to be constructed now require an instance of the dialect in order to access the uniquer. While they could look up the dialect in the context, it would have introduced a rather expensive lookup into each construction. Instead, the caller is expected to obtain the dialect instance and cache it. -- PiperOrigin-RevId: 249245199	2019-06-01 19:54:43 -07:00
Alex Zinenko	6804cf2429	Move SDBM infrastructure into a new SDBM dialect ... We now have sufficient extensibility in dialects to move attribute components such as SDBM out of the core IR into a dedicated dialect and make them optional. Introduce an SDBM dialect and move the code. This is a mostly non-functional change. -- PiperOrigin-RevId: 249244802	2019-06-01 19:54:33 -07:00
