* Fitting help messages to 80 character widthKrystalDelusion2022-08-241-1/+2
| | | | | | | | | Uses the regex below to search (using vscode): ^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\); Finds any log messages double indented (which help messages are) and checks if *either* there are is no newline character at the end, *or* the number of characters before the newline is more than 80.

* Make a few passes auto-call Mem::narrow instead of rejecting wide ports.Marcelina Kościelnicka2021-05-281-14/+1
| | | | | | This essentially adds wide port support for free in passes that don't have a usefully better way of handling wide ports than just breaking them up to narrow ports, avoiding "please run memory_narrow" annoyance.
* memory_bram: Reuse extract_rdff helper for make_outreg.Marcelina Kościelnicka2021-05-251-23/+38
| | | | | Also properly skip read ports with init value or reset when not making use of make_outreg. Proper support for matching those will land later.

* 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 Zeller2018-07-201-2/+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)
