whitequark 21d44ebec7 minisat: add missing include guard for WASI. 
Including signal.h used to be allowed in WASI by mistake, but it's
an error since SDK 11.
 2020-06-21 21:26:21 +00:00
whitequark b43c282e4e Add WASI platform support. 
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.

Henner Zeller 5c6e681673 Use static constexpr instead of static const where possible. 
In particular inside class declarations, a static const
assignment is technically not a definition, while constexpr is.

Claire Wolf f72b65b2a5 Using LFSR counter for ezSAT::manyhot() 
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.

Kristoffer Ellersgaard Koch 30c762d3a1 Fix all warnings that occurred when compiling with gcc9 2019-05-08 10:27:14 +02:00
whitequark efa278e232 Fix typographical and grammatical errors and inconsistencies. 
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.

Tim 'mithro' Ansell 1b231b442c minisat: Make update script executable. 2017-11-25 19:48:26 -08:00
Tim 'mithro' Ansell 34c9fbab53 minisat: Only define __STDC_XXX_MACROS if not already defined. 
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).
