RAG : RED : None AMBER: Worried about trunk failures with test runs. Number of testsuite failures after the atomics merge has increased - more below. .
Task Planned Estimated Actual Historical ~~~~~~~ Connect 2011.q4 preparation 28/10/2011 28/10/2011 28/10/2011 Linaro Tasks ~~~~~~~~~~~~ Fully Investigate the O3 performance regressions 31/01/2012 Writeup on the optimizations 31/12/2011 enabled with PGO ==Progress=== * Debugged the LTO failures for some time this week - not much progress. * The bootstrap failure with trunk turned out to be the same problem as with the CFG not being updated properly with some of the shrink-wrap patches from Alan M . This was fixed on trunk later on Monday. * Tested atomics fixes but the test results are overall looking ugly . Need to do some more debugging. Discovered GDB was broken for single stepping in ARM atomic sequences - Filed bug report https://bugs.launchpad.net/gdb-linaro/+bug/892008 here. * Looked into the vmul / vmla issue for a bit - did some experiments. Need to write these up and follow up . === Plans === * Commit the vcvt fixed point patch. * Finish experiments with the vmla stuff and find out more about this. * Finish debugging the LTO failures with PGO bootstrap. * Some research into the O3 perf issues. Absences. * Dec 19 - 31st Dec - Tentatively booked _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
