* Use C++11 final/override keywords.whitequark2020-06-181-2/+2
|
* Add WASI platform support.whitequark2020-04-301-2/+9
| | | | | | | | | | | | This includes the following significant changes: * Patching ezsat and minisat to disable resource limiting code on WASM/WASI, since the POSIX functions they use are unavailable. * Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform does not support spawning subprocesses (i.e. Emscripten or WASI). This definition hides the definition of `run_command()`. * Adding a new Makefile flag, DISABLE_SPAWN, present in the same condition. This flag disables all passes that require spawning subprocesses for their function.
* Merge pull request #1864 from boqwxp/cleanup_techmap_abcwhitequark2020-04-171-99/+80

* 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)
* Fix infinite loop in abc command under emscriptenRobert Ou2018-05-181-5/+7
