From b43c282e4e0de53b9323a5d8d85b07bc73324a17 Mon Sep 17 00:00:00 2001 From: whitequark Date: Mon, 11 Nov 2019 09:23:06 +0000 Subject: Add WASI platform support. 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. --- passes/techmap/abc9_exe.cc | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'passes/techmap/abc9_exe.cc') diff --git a/passes/techmap/abc9_exe.cc b/passes/techmap/abc9_exe.cc index bad91a224..0bf547921 100644 --- a/passes/techmap/abc9_exe.cc +++ b/passes/techmap/abc9_exe.cc @@ -420,11 +420,15 @@ struct Abc9ExePass : public Pass { } size_t argidx; +#if defined(__wasm) + const char *pwd = "."; +#else char pwd [PATH_MAX]; if (!getcwd(pwd, sizeof(pwd))) { log_cmd_error("getcwd failed: %s\n", strerror(errno)); log_abort(); } +#endif for (argidx = 1; argidx < args.size(); argidx++) { std::string arg = args[argidx]; if (arg == "-exe" && argidx+1 < args.size()) { -- cgit v1.2.3
