Merge pull request #1932 from YosysHQ/dave/cxxrtl-unclocked-read
cxxrtl: Fix handling of unclocked memory read ports
2020-04-15 05:34:29 +00:00
Marcelina Kościelnicka 6c16fd760b opt_expr: Add more $alu optimizations.
Detect the places in the $alu where the carry bit is constant (due to
const A[i] == B[i] ^ BI) and split it into smaller $alu at these points.

Also, make the existing const-carry detection for low bits more generic
(now handles cases where both BI and CI are constant, but not equal to
one another).

Fixes #1912.

Marcelina Kościelnicka 516857f3ba [NFCI] Deduplicate builtin FF cell types list
A few passes included the same list of FF cell types.  Make it a global
const instead.

The zinit pass also seems to include a list like that, but given that
it seems to be completely broken at the time (see #1568 discussion),
I'm going to pretend I didn't see that.
