The addition of Svadu support and removal of --mmu-dirty
command line flag results in the dirty_enabled configuration state
no longer being used. Remove the remnants of this state.
This is a minor change, turning processor_t from a child class of
isa_parser_t into a class that contains an isa_parser_t as a field.
The point is that it is a step toward separating out
"configuration" (and ISA string parsing) from processor state. This
should be helpful for rejigging things so that we construct more from
a supplied device tree.
This patch adds a --log argument to spike. If not given, the behaviour
is unchanged: messages logging execution of instructions and (if
commit logging is enabled) commits go to stderr.
If --log=P is given, Spike now writes these messages to a log file at
the path P. This is nice, because they are no longer tangled up with
other errors and warnings.
The code is mostly plumbing: passing a FILE* object through to the
functions that were using stderr. I've written a simple "log_file_t"
class, which opens a log file if necessary and yields it or stderr.
the tool can parse the instruction name from spike debug log to help
dsp kernel designer check what instructions have been used
