Martin and Jan, This set of patches introduces a huge number of testsuite regressions on AIX. AIX defaults to 32 bit. Although it supports a 64 bit "long long" type, it does not have 64 bit atomic operations on "long long" in 32 bit mode. All of the testcases fails with
ld: 0711-317 ERROR: Undefined symbol: .__atomic_fetch_add_8 ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. collect2: error: ld returned 8 exit status Testing LONG_LONG_TYPE_SIZE > 32 does not seem like a robust mechanism, especially later removing GCOV_TYPE_SIZE. I didn't think that __atomic_fetch_add_8 was required in 32 bit mode. Thanks, David
