Dear contributor, our automatic CI has detected problems related to your patch(es). Please find some details below. If you have any questions, please follow up on linaro-toolchain@lists.linaro.org mailing list, Libera's #linaro-tcwg channel, or ping your favourite Linaro toolchain developer on the usual project channel.
We appreciate that it might be difficult to find the necessary logs or reproduce the issue locally. If you can't get what you need from our CI within minutes, let us know and we will be happy to help.
We track this report status in https://linaro.atlassian.net/browse/GNU-1091 , please let us know if you are looking at the problem and/or when you have a fix.
First I suspect this was failing before r14-6822-g01f4251b8775c8 and I just return it back to that state.
The big ask I have is for reports like this, to include the exact gcc configure line that was used. In this case, is GCC configured to include neon by default? If so then the testcase needs to be updated to add an option to disable neon.
Hi Andrew,
We'll soon have configure and make info in the report.
If not, then someone else will need to look into why the testcase is failing. Basically, the update I did was disable vectorization on a loop which was not being vectorized before r14-6822-g01f4251b8775c8.
Ack.
Thanks,
