2022-01-27 | x86: Add string/memory function tests in RTM region | H.J. Lu | 1 | -0/+53 | |
At function exit, AVX optimized string/memory functions have VZEROUPPER which triggers RTM abort. When such functions are called inside a transactionally executing RTM region, RTM abort causes severe performance degradation. Add tests to verify that string/memory functions won't cause RTM abort in RTM region. (cherry picked from commit 4bd660be40967cd69072f69ebc2ad32bfcc1f206) |
