◆ TEST_CASE()

TEST_CASE ( "The basic_btb module does not overflow its bounds." )

The BTB module had a sneaky bug. If:

There is more than one core, and
The BTB mispredicts a direct branch, and
The IP was one less than a multiple of 1024, and
The IP was not present in the BTB Then, there would be a buffer overflow and a later prediction to some other core will segfault.
