* Add WASI platform support.whitequark2020-04-3017-30/+167
| | | | | | | | | | | | 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.

|\ \ \ | | | | | | | | cxxrtl: fix attribute syntax, minor fixes

| | | | | | | | | | | | | | | | | | | | The former prefix does not need to be escaped in Verilog, unlike the latter, and the Yosys convention is to use the former.
