[PATCH] D36911: TableGen: Add --gen-register-info-debug-dump

[Matthias Braun via Phabricator via llvm-commits]

MatzeB created this revision.
Herald added a subscriber: mcrosier.

Adds a new --gen-register-info-debug-dump mode to tablegen that dumps various register related information:

- List of register classes with super and subclasses
- List of subregister indexes with lanemasks
- List of registers with subregisters

I will use this in an upcoming commit to create a test.
It may also be useful for target developers wanting to get an overview of all the register related information, esp. the things inferred by tablegen and not directly visible in the .td file.
