| * | Add WASI platform support. | whitequark | 2020-04-30 | 3 | -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. | |||||

| | | | | | | | | | | | | | | | | | | | 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. | |||||

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, ``` module top(inout io); assign io = 1'bx; endmodule ``` would have the `io` pin demoted to input (same happens for `1'bz`, but not for `1'b0` or `1'b1`), resulting in check failures later on.
