The datasym workload is to check if perf mem command gets the data addresses precisely. This is needed for data symbol test. $ perf test -w datasym I had to keep the buf1 in the data section, otherwise it could end up in the BSS and was mmaped as a separate //anon region, then it was not symbolized at all. It needs to be fixed separately. Committer notes: Add a -U _FORTIFY_SOURCE to the datasym CFLAGS, as the main perf flags set it and it requires building with optimization, and this new test has a -O0.
