c6707688ba improved get_arith_value() in theory_str 
Since the root of the eqc of an integer term should be a constant
if there is a constant in that eqc, we can ask for it directly
without either iterating over the entire eqc or
asking the arithmetic solver (and receiving potentially stale info).

630863619b [TravisCI] Add Z3_WARNINGS_AS_ERRORS environment variable to 
control the `WARNINGS_AS_ERRORS` CMake option.
 2017-07-09 14:44:20 +01:00

6e2ca69654 [CMake] Change the WARNINGS_AS_ERRORS option from BOOL to STRING 
to allow a new mode `SERIOUS_ONLY`.

Modes:

`ON` - All warnings are treated as errors (same as before)
`OFF` - Warnings are not treated as errors (same as before)
`SERIOUS_ONLY` - A subset of "serious" warnings are treated as errors.

Upgrade code is included to upgrade old CMake cache's to use the new
type of `WARNINGS_AS_ERRORS`. We should remove it eventually. The
user's previous setting is preserved when doing this.

Very few warnings are treated as errors for now. Developers can
add more later as they see fit.
