* xilinx: add SCC test for DSP48E1 * xilinx: Gate DSP48E1 being a whitebox behind ALLOW_WHITEBOX_DSP48E1 Have a test that checks it works through ABC9 when enabled * abc9 to break SCCs using $__ABC9_SCC_BREAKER module * Add test * abc9_ops: remove refs to (* abc9_keep *) on wires * abc9_ops: do not bypass cells in an SCC * Add myself to CODEOWNERS for abc9* * Fix compile * abc9_ops: run -prep_hier before scc * Fix tests * Remove bug reference pending fix * abc9: fix for -prep_hier -dff * xaiger: restore PI handling * abc9_ops: -prep_xaiger sigmap * abc9_ops: -mark_scc -> -break_scc * abc9: eliminate hard-coded abc9.box from tests Also tidy up * Address review
