opt_lut_ins: fix name of global object. NFCI 2024-06-28 15:12:36 +00:00
Emil J. Tywoniak 01f332e750 opt_expr: reduce mostly harmless warning to log 2024-06-25 20:18:49 +02:00
Martin Povišer fa4a2b6b0d opt_expr: In clkinv loop ignore irrelevant cells early 
Each call to `handle_clkpol_celltype_swap` has a conversion of the
cell's type ID to an allocated string. This can sum up to a
non-negligible time being spent in the clkpol code even for a design
which doesn't have any flip-flop gates.

Martin Povišer 7a8a69b65c opt_expr: Revisit sorting in `replace_const_cells` 
Avoid building a cell-to-inbit map when sorting the cells, add a warning
if we are unable to sort, and move the code treating non-combinational
cells ahead of the rest (this means we don't need to pass
non-combinational cells to the TopoSort object at all).

Philippe Sauter 2f0f10cb87 peepopt: limit padding from shiftadd 
The input to a shift operation is padded.
This reduced the final number of MUX cells
but during techmap it can create huge
temporary multiplexers in the log shifter.
This significantly increases runtime and resources.

A limit is added with a warning when it is used.
