I could have use a child class of ExprOp specific for conditions, but
I prefer to keep a better modularity by just using "<s", "<u" as a new op
I don't add the size issue in expression/expression.py (such as 'parity')
because we don't want dependencies from this file to
expression/simplifications_cond (for TOK_*)
* API has changed, so old scripts need updates
* See example for API usage
* Use tcc or llvm for jit emulation
* Go to test and run test_all.py to check install
Enjoy !
