| * | opt_expr: Add more $alu optimizations. | Marcelina Kościelnicka | 2020-04-14 | 1 | -4/+52 |
| | | | | | | | | | | | | 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. | ||||
