* Fixes for some of clang scan-build detected issuesMiodrag Milanovic2023-01-171-2/+2

* tcl: Update help message to mention 'tee -s'Jannis Harder2022-12-051-2/+2

* tcl: Unset both result.json and result.string only before calling passJannis Harder2022-12-051-2/+1

* tcl: Don't exit repl on recoverable command errorsJannis Harder2022-12-021-4/+34
|
* tcl: Return scratchpad result.json and result.string as tcl objectsJannis Harder2022-12-021-2/+57
| | | | | | | | | | | | | | | | | This makes it possible for yosys commands to return values when invoked as tcl commands. Right now no commands natively support this, but the tee command can be used with json output like this: ```tcl set stat [yosys tee -q -s result.json stat -json -top top] dict get $stat modules \\top num_cells_by_type \$pmux ``` Or with newline separated lists like this: ```tcl split [yosys tee -q -s result.string select -list top] "\n" ```

* Update tcl doc, yosys does not return data to tclrockybulwinkle2022-06-231-0/+6
| | | | | | | This pull request is to address YosysHQ/yosys#2980. The documentation, as originally written, does not make it clear that yosys commands, when used within a tcl script, do not return any value to the tcl script. This pull request notes this and offers a workaround via tee as noted in the issue.

* Observe $TMPDIR variable when creating tmp filesMohamed A. Bamakhrama2022-05-271-1/+30
| | | | | | | | | POSIX defines $TMPDIR as containing the pathname of the directory where programs can create temporary files. On most systems, this variable points to "/tmp". However, on some systems it can point to a different location. Without respecting this variable, yosys fails to run on such systems. Signed-off-by: Mohamed A. Bamakhrama <mohamed@alumni.tum.de>

* Replace "ILANG" with "RTLIL" everywhere.whitequark2020-08-261-3/+3
| | | | | | | | | | 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.

* Add WASI platform support.whitequark2020-04-301-9/+18
| | | | | | | | | | | | 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.
* Support custom PROGRAM_PREFIXMiodrag Milanovic2020-04-101-1/+10
