+* TableGen's syntax for instruction selection patterns has been simplified.
+ Instead of specifying types indirectly with register classes, you should now
+ specify types directly in the input patterns. See ``SparcInstrInfo.td`` for
+ examples of the new syntax. The old syntax using register classes still
+ works, but it will be removed in a future LLVM release.
