| * | Add v2 memory cells. | Marcelina Kościelnicka | 2021-08-11 | 1 | -3/+6 |

| * | Refactor common parts of SAT-using optimizations into a helper. | Marcelina Kościelnicka | 2021-08-09 | 1 | -57/+18 |
| | | | | | | | | | | | | | | This also aligns the functionality: - in all cases, the onehot attribute is used to create appropriate constraints (previously, opt_dff didn't do it at all, and share created one-hot constraints based on $pmux presence alone, which is unsound) - in all cases, shift and mul/div/pow cells are now skipped when importing the SAT problem (previously only memory_share did this) — this avoids creating clauses for hard cells that are unlikely to help with proving the UNSATness needed for optimization | ||||

| * | Use C++11 final/override keywords. | whitequark | 2020-06-18 | 1 | -2/+2 |

| * | Add flooring division operator | Xiretza | 2020-05-28 | 1 | -1/+3 |
| | | | | | | | | | | | The $div and $mod cells use truncating division semantics (rounding towards 0), as defined by e.g. Verilog. Another rounding mode, flooring (rounding towards negative infinity), can be used in e.g. VHDL. The new $divfloor cell provides this flooring division. This commit also fixes the handling of $div in opt_expr, which was previously optimized as if it was $divfloor. | ||||
| * | Add flooring modulo operator | Xiretza | 2020-05-28 | 1 | -1/+3 |
| | | | | | | | | | | | | The $div and $mod cells use truncating division semantics (rounding towards 0), as defined by e.g. Verilog. Another rounding mode, flooring (rounding towards negative infinity), can be used in e.g. VHDL. The new $modfloor cell provides this flooring modulo (also known as "remainder" in several languages, but this name is ambiguous). This commit also fixes the handling of $mod in opt_expr, which was previously optimized as if it was $modfloor. | ||||

| * | Use ID() macro in all of passes/opt/ | Clifford Wolf | 2019-08-11 | 1 | -173/+173 |
| | | | | | | | | | | | This was obtained by running the following SED command in passes/opt/ and then using "meld foo.cc foo.cc.orig" to manually fix all resulting compiler errors. sed -i.orig -r 's/"\\\\([a-zA-Z0-9_]+)"/ID(\1)/g; s/"(\$[a-zA-Z0-9_]+)"/ID(\1)/g;' *.cc Signed-off-by: Clifford Wolf <clifford@clifford.at> | ||||

| * | Consistent use of 'override' for virtual methods in derived classes. | Henner Zeller | 2018-07-20 | 1 | -2/+2 |
| | | | | | | | | | | o Not all derived methods were marked 'override', but it is a great feature of C++11 that we should make use of. o While at it: touched header files got a -*- c++ -*- for emacs to provide support for that language. o use YS_OVERRIDE for all override keywords (though we should probably use the plain keyword going forward now that C++11 is established) | ||||
