...s 'true' and 'false' were added to TableGen to improve the readability of the code. * The !sub bang operator was added to perform subtraction. * The !interleave operator was added to concatenate a list of strings with a delimiter between each item. This is simpler and faster than !foldl. * The !filter operator was added to filter a list of items based on a boolean predicate expression. This is simpler and faster than !foldl. * All six comparison operators now work on strings: !eq, !ne, !gt, !ge, !lt, !le. * The !eq and !ne operators now work on records. This eliminates many !ca...

...rather long list of ~30 patches which do a bunch of things in lib/TableGen/ such as: - better and earlier error messages - cleanup type checking - cleanup variable resolving - cleanup record instantiation - late generation of anonymous records that appear in expressions - cleanup !foreach - add !foldl - add !isa<type>(...) and make !cast more useful - add !dag builtin to generate DAG nodes from lists - some other minor new built-ins like !size, !le, !lt, !ge, !gt - add a defset mechanism for collecting records which can then later be looped over in a foreach statement - make foreach state...

...nerated, that would help a lot.​ - cleanup !foreach > ​+1 for having scoped temporary variable. ATM tablegen can use a class field for that, but using it in the global scope still needs a record for it. Things also go wrong when one accidentally uses a record/field with a known value.​ - add !foldl > - add !isa<type>(...) and make !cast more useful > ​Nice.​ > - add !dag builtin to generate DAG nodes from lists > ​Yes, please!

...[proposed](http://lists.llvm.org/pipermail/cfe-dev/2018-March/057113.html) making the C++ `atomic` and C `stdatomic.h` headers explicitly incompatible, resulting in a short and easy to understand error message if both are included in the same translation unit. ## LLVM commits * TableGen gained `!foldl` and `!isa` operations, as well as a new `defset` statement.
