| | | | | | | | | | | | | | | | | | | | | | | | log_assert(false) never returns and thus can't fall through, but gcc doesn't seem to think that far. Making it the last case avoids the problem entirely.

| | | | | | | | | | | | | | | | | | | | C++17 introduced [[fallthrough]], GCC and clang had their own vendored attributes before that. MSVC doesn't seem to have such a warning at all.
* | | | intel_alm: direct LUTRAM cell instantiationDan Ravensloft2020-05-079-52/+163
| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | By instantiating the LUTRAM cell directly, we avoid a trip through altsyncram, which speeds up Quartus synthesis time. This also gives a little more flexibility, as Yosys can build RAMs out of individual 32x1 LUTRAM cells. While working on this, I discovered that the mem_init0 parameter of <family>_mlab_cell gets ignored by Quartus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
