| | * Fix FIRRTL to Verilog process instance subfield assignment.Jim Lawson2019-02-251-8/+20
| | | | | | | | | | | | | | | | | | Don't emit subfield assignments: bits(x, y, z) <= ... - but instead, add them to the reverse-wire-map where they'll be treated at the end of the module. Enable tests which were disabled due to incorrect treatment of subfields. Assume the `$firrtl2verilog` variable contains any additional switches to control verilog generation (i.e. `--no-dedup -X mverilog`)

| | * Update cells supported for verilog to FIRRTL conversion.Jim Lawson2019-02-151-48/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue warning messages for missing parameterized modules and attempts to set initial values. Replace simple "if (cell-type)" with "else if" chain. Fix FIRRTL shift handling. Add support for parameterized modules, $shift, $shiftx. Handle default output file. Deal with no top module. Automatically run pmuxtree pass. Allow EXTRA_FLAGS and SEED parameters to be set in the environment for tests/tools/autotest.mk. Support FIRRTL regression testing in tests/tools/autotest.sh Add xfirrtl files to test directories to exclude files from FIRRTL regression tests that are known to fail.
