* Add WASI platform support.whitequark2020-04-301-5/+6
| | | | | | | | | | | | 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.
* Improve ezsat onehot encoding schemeClaire Wolf2020-04-021-14/+28

* Using LFSR counter for ezSAT::manyhot()Claire Wolf2020-04-021-0/+118
| | | | | | | | The only user of this API right now is the puzzle3d benchmark and it sees a slight reduction in CNF size from this, but the performance difference is within the noise of measurement on my system. Signed-off-by: Claire Wolf <claire@symbioticeda.com>
* Fix typographical and grammatical errors and inconsistencies.whitequark2019-01-021-1/+1
| | | | | | | | | | | | The initial list of hits was generated with the codespell command below, and each hit was evaluated and fixed manually while taking context into consideration. DIRS="kernel/ frontends/ backends/ passes/ techlibs/" DIRS="${DIRS} libs/ezsat/ libs/subcircuit" codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint More hits were found by looking through comments and strings manually.
* minisat: Only define __STDC_XXX_MACROS if not already defined.Tim 'mithro' Ansell2017-11-251-1/+5
| | | | | | | | | | | | | | | | | Replace; #define __STDC_LIMIT_MACROS #define __STDC_FORMAT_MACROS With #ifndef __STDC_LIMIT_MACROS #define __STDC_LIMIT_MACROS #endif #ifndef __STDC_FORMAT_MACROS #define __STDC_FORMAT_MACROS #endif This fixes a compile warning if you are defining these macros in your CXXFLAGS (as some distros do).
