CMPccXADD is a new set of instructions in the latest Intel platform Sierra Forest. This new instruction set includes a semaphore operation that can compare and add the operands if condition is met, which can improve database performance.
This test suite provides basic functional check to ensure CMPccXADD works properly.
make
# To run a specific case
./cmpccxadd -t <testcase_id>
(for example, cmpbexadd_above) ./cmpccxadd -t 1
Test results (PASS or FAIL) will be printed out.
