AlignerPlugin

class AlignerPlugin extends FiberPlugin with AlignerService with InjectorService

This plugin will deserialize the aligned fetched words into instructions. - withBuffer => A Fetch.WORD sized buffer will be added to allow unaligned instruction to be read - !withBuffer => Fetch lanes directly feed Decode lanes without muxes. This doesn't support RVC - Warning, if the plugin start to hold stats => you need to notify TrapService when flush a is pending

Here are the challenges : - When RVC is enabled, 32 bits instruction can be unaligned, so one instruction my need 2 fetch word - Branch prediction (ex: from a BTB) may produce a broken stream of fetched word on 32 bits unaligned instruction aswell producing predictions which aren't aligned with the real instruction layout (ex prediction from fetched word slice 2, while slice 2 isn't the last slice of a instruction) - Handeling all the corner cases while keeping the combinatorial path low
