whitequark e561a3a76f flatten: simplify. NFC. 
The `celltypeMap` always maps `x` to `{x}`.

whitequark 6783876807 flatten: simplify. NFC. 
The `design` and `map` designs are always the same when flattening.

whitequark 9338ff66b9 RTLIL: factor out RTLIL::Module::addMemory. NFC. 2020-06-04 00:02:12 +00:00
whitequark ebbbe2156e flatten: rename techmap-related stuff. NFC. 2020-06-04 00:02:12 +00:00
whitequark 76c4ee4ea5 techmap, flatten: remove dead options. 
After splitting the passes, some options can never be activated,
and most conditions involving them become dead. Remove them, and also
all of the newly dead code.

whitequark 6ac54a74fe flatten: split from techmap. 
Although the two passes started out very similar, they diverged over
time and now have little in common. Moreover, `techmap` is extremely
complex while `flatten` does not have to be, and this complexity
interferes with improving `flatten`.

whitequark f3e86bb32a techmap: simplify. 
`rewrite_filename` is already called in `Frontend::extra_args`.

whitequark 68d747f767 techmap: use +/techmap.v instead of an ad-hoc code generator. 2020-06-02 23:43:20 +00:00
