Baruch Sterin 2343da6bf1 Makefile: support ccache for compiling ABC. 
Surround $(CC), $(CXX) with double quotes when calling depends.sh, to allow space-delimited compilation tools to be used.

Sean Cross 11c4f998b2 Makefile: break apart steps in `make clean` 
The `make clean` target consists of a single `rm` call that passes every
generated file, object file, and dependency directory.  This results in
a command line that's around 53,800 characters long.

On Linux, the maximum length of a command line is 131,072 or 262,144
characters, however on Windows the limit is 32,768.

The 53,800 character command simply fails to run on Windows, which is a
problem when the first command that gets run is `make clean`.

Break this target into steps, first removing the output files, then the
object files, then any generated garbage, and then the object depedency
directories.

This fixes `make clean` (and as a result yosys) on Windows.

whitequark 128ba6ebc5 Allow changing the `ar` binary. 
This is useful for cross-compilation, when build `ar` cannot handle
the target object files.

The invocation of `ranlib` is replaced with `ar s`, which is
equivalent and simplifies the build system a bit.

Baruch Sterin 5ab3f0fa6b Patch by Larry Doolittle to allow out-of-source builds of ABC. 
Usage:

Starting from an empty directory:

(1) set AS to point to the location of ABC

(2) reconstruct the directory structure of ABC in the new directory:

    mkdir -p `cd $AS && find src -type d`

(3) Build ABC:

    make -f $AS/Makefile VPATH=$AS ABCSRC=$AS

Baruch Sterin b9dfb992c7 (1) Makefile: added a shared library target, (2) no longer compile the main function as part of libabc.a 2016-12-22 18:15:29 -08:00
Bruno Schmitt 5351ab4b13 xSAT is an experimental SAT Solver based on Glucose v3(see Glucose copyrights below) and ABC C version of 
MiniSat (bsat) developed by Niklas Sorensson and modified by Alan Mishchenko. It’s development has reached
sufficient maturity to be committed in ABC, but still in a beta state.

TODO:
* Read compressed CNF files.
* Study the use of floating point for variables and clauses activity.
* Better documentation.
* Improve verbose messages.
* Expose parameters for tuning.
