* Add WASI platform support.whitequark2020-04-303-3/+14
| | | | | | | | | | | | 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 #1974 from YosysHQ/eddie/abc9_disable_mfsEddie Hung2020-04-231-2/+17

| | | | | | | | | | | | | | | | | | This pass is a proper subset of opt_rmdff, which is called by opt, which is called by every synth flow in the coarse part. Thus, it never actually does anything and can be safely removed.
