Fix building and running unit tests (#5374)
* Fix building and running unit tests

* Enable unit tests

* Add gtest always

* test-sanitizers.yml: Use makefile.conf

* proper test setup

* make it run on macOS

* Run libyosys build only for unit tests after testing is done

* Disable LTO on public CI

Emil J. Tywoniak 01de9fb453 hashlib: extend unit test with subset collisions, shorten runtime 2025-08-20 00:08:23 +02:00
Robert O'Callahan 3a5742ffd2 Improve commutative hashing.
The simple XOR `commutative_eat()` implementation produces a lot of collisions.
https://www.preprints.org/manuscript/201710.0192/v1/download is a useful reference on this topic.

Running the included `hashTest.cc` without the hashlib changes, I get 49,580,349 collisions.
The 49,995,000 (i,j) pairs (0 <= i < 10000, i < j < 10000) hash into only 414,651 unique hash values.
We get simple collisions like (0,1) colliding with (2,3).

With the hashlib changes, we get only 707,099 collisions and 49,287,901 unique hash values.
Much better! The `commutative_hash` implementation corresponds to `Sum(4)` in the paper
mentioned above.

Robert O'Callahan ffd52a0d8e Making `stringf()` use the format conversion specs as-is without widening them.
And make sure our fast-path for `%d` and `%u` narrows to `int` correctly.

Resolves #5260

Jannis Harder 7cd822b7f5 rtlil: Add {from,to}_hdl_index methods to Wire
In the past we had the occasional bug due to some place not handling all
4 combinations of upto/downto and zero/nonzero start_offset correctly.

Emil J. Tywoniak 785bd44da7 rtlil: represent Const strings as std::string 2024-10-14 06:28:12 +02:00
rodrigosiqueira e0152319f5 Added required structure to implement unit tests
Added modifications inside the main Makefile to refers the unit test Makefile.
Added separated Makefile only for compiling unit tests.
Added simple example of unit test.
