| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The workflow of debugging fatal pass errors in Yosys is flawed in three ways: 1. Running Yosys under a debugger is sufficient for the debugger to catch some fatal errors (segfaults, aborts, STL exceptions) but not others (`log_error()`, `log_cmd_error()`). This is neither obvious nor easy to remember. 2. To catch Yosys-specific fatal errors, it is necessary to set a breakpoint at `logv_error_with_prefix()`, or at least, `logv_error()`. This is neither obvious nor easy to remember, and GDB's autocomplete takes many seconds to suggest function names due to the large amount of symbols in Yosys. 3. If a breakpoint is not set and Yosys encounters with such a fatal error, the process terminates. When debugging a crash that takes a long time to reproduce (or a nondeterministic crash) this can waste a significant amount of time. To solve this problem, add a macro `YS_DEBUGTRAP` that acts as a hard breakpoint (if available), and a macro `YS_DEBUGTRAP_IF_DEBUGGING` that acts as a hard breakpoint only if debugger is present. Then, use `YS_DEBUGTRAP_IF_DEBUGGING` in `logv_error_with_prefix()` to obviate the need for a breakpoint on nearly every platform. Co-Authored-By: Alberto Gonzalez <boqwxp@airmail.cc>

| * | | 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.
