I'm planning to remove StringRef::equals in favor of
StringRef::operator==.
- StringRef::operator==/!= outnumber StringRef::equals by a factor of
10 under mlir/ in terms of their usage.
- The elimination of StringRef::equals brings StringRef closer to
std::string_view, which has operator== but not equals.
- S == "foo" is more readable than S.equals("foo"), especially for
!Long.Expression.equals("str") vs Long.Expression != "str".
This PR massively reorganizes the Test dialect's source files. It moves
manually-written op hooks into `TestOpDefs.cpp`, moves format custom
directive parsers and printers into `TestFormatUtils`, adds missing
comment blocks, and moves around where generated source files are
included for types, attributes, enums, etc. into their own source file.
This will hopefully help navigate the test dialect source code, but also
speeds up compile time of the test dialect by putting generated source
files into separate compilation units.
This also sets up the test dialect to shard its op definitions, done in
the next PR.
TestDialect.cpp along with the ODS-generated files amounts to around
100k LoC and takes a significant amount of time to compile. Factor out
the test ops related to testing the sytnax and assembly format, which
are a relatively large and well delimited group, into a separate set of
files.
Also factor out dialect interfaces into a separate file.
