I am seeing a whole lot of failures in the tests on trunk. From discussions
with Chris and others, I should not be seeing this.
Here's a typical case:
[x86_64-off-opt]: Core was generated by `Output/simple_throw.cbe'.
[x86_64-off-opt]: Program terminated with signal 6, Aborted.
[x86_64-off-opt]: #0 0x00002b0620792b95 in raise () from /lib64/libc.so.6
[x86_64-off-opt]: #0 0x00002b0620792b95 in raise () from /lib64/libc.so.6
[x86_64-off-opt]: #1 0x00002b0620793f90 in abort () from /lib64/libc.so.6
[x86_64-off-opt]: #2 0x00002b0620621af4 in
__gnu_cxx::__verbose_terminate_handler () from /usr/lib64/libstdc++.so.6
[x86_64-off-opt]: #3 0x00002b062061fc36 in ?? () from
/usr/lib64/libstdc++.so.6
[x86_64-off-opt]: #4 0x00002b062061fc63 in std::terminate () from
/usr/lib64/libstdc++.so.6
[x86_64-off-opt]: #5 0x00002b062061fd4a in __cxa_throw () from
/usr/lib64/libstdc++.so.6
[x86_64-off-opt]: #6 0x0000000000400603 in main ()
[x86_64-off-opt]: /ptmp/dag/llvm-project.official/llvm/trunk/projects/test-
suite/DiffOutput.sh
"/ptmp/dag/build.llvm.trunk.official.opt/x86_64-unknown-
linux-gnu/Release/bin/fpcmp " cbe simple_throw
[x86_64-off-opt]: ******************** TEST (cbe) 'simple_throw' FAILED!
********************
[x86_64-off-opt]: Execution Context Diff:
[x86_64-off-opt]: /ptmp/dag/build.llvm.trunk.official.opt/x86_64-unknown-

between 'A' and 't'
[x86_64-off-opt]: ******************** TEST (cbe) 'simple_throw'

Any idea why I would be seeing these and when others don't? Is it because
the
buildbots don't build Release tools? A quick glance suggests all of these
failures in are Release mode.
I am on x86_64 Linux. Is anyone else able to reproduce a bunch of failures in
Release mode?
I am using gcc 4.4.2. Is anyone else using it successfully to build Release
tools? Possibly we have another broken gcc.

But what does "pass" mean? [x86_64-off-opt]: Testing Time: 127.55s [x86_64-off-opt]: Expected Passes : 5006 [x86_64-off-opt]: Expected Failures : 33 [x86_64-off-opt]: Unsupported Tests : 66 Is that really passing? Even though I see a bunch of "FAIL:" lines in the make output? Not 33 of them, however. -Dave
