* memory_collect: do not truncate 'x from \INIT.whitequark2018-12-211-3/+0
| | | | | | | The semantics of an RTLIL constant that has less bits than its declared bit width is zero padding. Therefore, if the output of memory_collect will be used for simulation, truncating 'x from the end of \INIT will produce incorrect simulation results.

* memory_bram: Fix initdata bit order after shufflingGraham Edgecombe2018-12-111-0/+17
| | | | | | | | | | | | | In some cases the memory_bram pass shuffles the order of the bits in a memory's RD_DATA port. Although the order of the bits in the WR_DATA and WR_EN ports is changed to match the RD_DATA port, the order of the bits in the initialization data is not. This causes reads of initialized memories to return invalid data (until the initialization data is overwritten). This commit fixes the bug by shuffling the initdata bits in exactly the same order as the RD_DATA/WR_DATA/WR_EN bits.

* Consistent use of 'override' for virtual methods in derived classes.Henner Zeller2018-07-209-18/+18
| | | | | | | | | 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)
