pvanhout	c0719f3bac	[RFC][TableGen][GlobalISel] Add Combiner Match Table Backend ... Adds a new backend to power the GISel Combiners using the InstructionSelector's match tables. This does not depend on any of the data structures created for the current combiner and is intended to replace it entirely. See the RFC for more details: https://discourse.llvm.org/t/rfc-matchtable-based-globalisel-combiners/71457/6 Note: this would replace D141135.

pvanhout	908d0d54b8	[TableGen][GlobalISel] Add Generic MatchTableExecutor Emitter ... Move all of the reusable logic out of `GlobalISelEmitter.cpp` into a `GlobalISelMatchTableExecutorEmitter` class so the future combiner backend can use it as well. Depends on D153755 Reviewed By: aemerson Differential Revision: https://reviews.llvm.org/D153756	2023-07-11 09:42:35 +02:00
