An attempt at getting closer to building what our Linux users use on a daily basis is not futile. If Linux builds are spread over multiple compilers, then we obviously can't change to a representative compiler. But if a large majority of Linux builds aren't using PGO and we know there's a class of bugs specific to PGO (from experience), it makes complete sense from the quality perspective to match that specific configuration. Discussions are ongoing as to whether disabling the test is our best path forward here, given engineering opposition to disabling PGO. -Alex On Nov 13, 2012, at 10:07 PM, Taras Glek <tg...@mozilla.com> wrote: > On 11/13/2012 3:53 PM, Alex Keybl wrote: >> If the Snappy initiative (or any other group of Mozillians) has short-term >> plans to evangelize the perf wins of PGO to Linux distros, I agree that we >> should leave PGO builds and testing enabled on Linux and further investigate >> the mysterious crash in bug 799295.
