* Fix double-free on unmatched logger error patternZachary Snow2021-02-231-3/+3
| | | | | | | When an expected logger error pattern is unmatched, the logger raises another (hidden) error. Because of the previous ordering of actions, `logv_error_with_prefix()` would inadvertently invoke `yosys_atexit()` twice, causing a double-free.
* Replace "ILANG" with "RTLIL" everywhere.whitequark2020-08-261-5/+5
| | | | | | | | | | The only difference between "RTLIL" and "ILANG" is that the latter is the text representation of the former, as opposed to the in-memory graph representation. This distinction serves no purpose but confuses people: it is not obvious that the ILANG backend writes RTLIL graphs. Passes `write_ilang` and `read_ilang` are provided as aliases to `write_rtlil` and `read_rtlil` for compatibility.

* kernel: Trap in `log_error()` when a debugger is attached.whitequark2020-05-031-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | (IEEE1800-2017 section 20.11) This PR allows us to use $info/$warning/$error/$fatal **at elaboration time** within a generate block. This is very useful to stop a synthesis of a parametrized block when an illegal combination of parameters is chosen.
