Provide initial work that better handles the problem of needing to filter
files in order to enable specific layers. This adds a new member
function,
shouldIncludeFile
which returns aPartialFunction
that isdefined only if the file being examined is a layer file (as defined in the
FIRRTL ABI for extract layers) and returns true if that layer file should
be included in order to enable the requested layers.
Change both ChiselSim and svsim to no longer use the
filter
function ofLayerControl
. Migrate both to useshouldIncludeFile
partial function.The latter is a much better API as it reserves the handling of files that
are outside the domain of the filter to ChiselSim and svsim.
Remove
LayerControl
's filter as this is no longer load-bearing.
