Eddie Hung a8ab74285b zinit: handle $__DFFS?E?_[NP][NP][01] too 2020-04-14 13:08:23 -07:00
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.

Suppress output of Makefile.conf when printing source versions 
The make targets echo-yosys-ver, echo-git-ver and echo-abc-rev can be
used to programmatically extract contents of make variables for external
scripts. Unfortunately, when a Makefile.conf exists, its contents would
also be echoed, making the output almost unusable. This patch
selectively disables this functionality for these special targets.
