[Larin, Sergei] The core of bundler is the DFA state machine, which also _must_ be a part of any VLIW scheduler, so in my Hexagon VLIW "custom" scheduler (I actually have two - SDNode and MI based) I virtually __create__ bundles, but discard them at the end of pass, only to recreate them again later in the standalone bundler. Second attempt is riddled with additional false dependencies (anti, output etc.) introduced by the register allocation, so bundling quality is affected. > > > Re-bundling is also a...

Also as a VLIW backend maintainer, I just have to say it :) - We do need to have a way to assign bundles much earlier than we do now. And it needs to be intertwined with scheduling (Bundler currently reuses a good chunk of scheduler infrastructure). It is also obvious
