Sadly, the testsuite is very unreliable on windows (even though it improved a lot recently). I now let it first run with current master as baseline: # of expected passes 42520 # of unexpected failures 3334 # of unexpected successes 1 # of expected failures 25 # of known failures 45 # of untested testcases 133 # of unresolved testcases 574 # of unsupported tests 356 # of paths in test names 32 # of duplicate test names 60 Then one time with my AVX changes: # of expected passes 41663 # of unexpected failures 3686 # of unexpected successes 1 # of expected failures 26 # of known failures 45 # of untested testcases 135 # of unresolved testcases 565 # of unsupported tests 355 # of paths in test names 31 # of duplicate test names 54 And again with my changes, so you see what I mean: # of expected passes 44348 # of unexpected failures 2894 # of unexpected successes 1 # of expected failures 23 # of known failures 45 # of untested testcases 134 # of unresolved testcases 306 # of unsupported tests 359 # of paths in test names 30 # of duplicate test names 44 I think it's funny that even the duplicate test names are different each time. This was only for gdb.arch/gdb.base/gdb.cp, most of the others wouldn't work anyways. I can tell you that I first implemented this AVX stuff almost 2 years ago, and had no problems using gdb related to it since then. Hannes
