Commit 10269a2ca2b08c ("perf test sample-parsing: Add endian test for struct branch_flags")
broke the test case 27 (Sample parsing) on s390 on linux-next tree:
# ./perf test -Fv 27
27: Sample parsing
--- start ---
parsing failed for sample_type 0x800
---- end ----
Sample parsing: FAILED!
#
The cause of the failure is a wrong #define BS_EXPECTED_BE statement
in above commit. Correct this define and the test case runs fine.
Output After:
# ./perf test -Fv 27
27: Sample parsing :
--- start ---
---- end ----
Sample parsing: Ok
#
Fixes: 10269a2ca2b08c ("perf test sample-parsing: Add endian test for struct branch_flags")

Hi Thomas,
Thanks for the fix. Not sure, I guess I messed up my big endian setup or
test run I had before sending
the patch. My bad. It fails for me too, but with your patch the issue
fixed.
