fb1deb1fef Tests: update all tests to add fields for L1I 2020-05-10 17:02:45 +00:00
Veselin Georgiev
87f3052a7b Add a test with L4 cache (courtesy of @phprus).
The test is a snapshot of a Haswell i7 (a.k.a. "Crystalwell") core.
This is the only test in the test DB right now which has lines for
L4 cache size, associativity and cacheline size different than "-1".

Also update create_test.py to accommodate for the new fields.

94fc6ae36a Modify the table matcher a bit. Put some weights on the different fields.
Priously all fields in the matchtable were treated equal in importance.
With this change, the cache size a taken with half the weight in the decision.

Also add detection entries for some more recent Haswells, and the respective
tests. These are an i5 Haswell from a Mac Book Pro, and a i7 Haswel from
Thinkpad T540.

046d2ca2ab Better support for AVX, AVX2, BMI1 and BMI2 instruction set detection.
- Detect AVX and AVX2 on both Intel and AMD CPUs
- Detect BMI1 and BMI2 instruction sets (BMI2 is only on Haswell, BMI1 is
  also present on Bulldozers).
- Fix tests to reflect changes.
