* This patch adds support for defining the ABC location at runtime instead of ↵Ethan Mahintorabi2020-10-281-1/+6
| | | | | | at compile time. This is helpful in build systems like bazel which do not have stable locations for binaries or directories during the compilation phase. This change should be backwards compatible with the existing behavior.

|
* Add WASI platform support.whitequark2020-04-301-2/+9
| | | | | | | | | | | | 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.
