* unicorn: Add modified ver of unicorns const gen * unicorn: Use upstream consts These consts were generated from the dev branch of unicorn * unicorn: Split common consts into multiple enums * unicorn: Remove arch prefix from consts * unicorn: Add new windows dll Windows 10 - MSVC x64 shared build * unicorn: Use absolute path for const generation * unicorn: Remove fspcr patch * unicorn: Fix using the wrong file extension For some reason _NativeLibraryExtension evaluates to ".so" even on Windows. * unicorn: Add linux shared object again * unicron: Add DllImportResolver * unicorn: Try to import unicorn using an absolute path * unicorn: Add clean target * unicorn: Replace IsUnicornAvailable() methods * unicorn: Skip tests instead of silently passing them if unicorn is missing * unicorn: Write error message to stderr * unicorn: Make Interface static * unicron: Include prefixed unicorn libs (libunicorn.so) Co-authored-by: merry <git@mary.rs> * unicorn: Add lib prefix to shared object for linux Co-authored-by: merry <git@mary.rs>
