    I've left mozjs52
    compiling on mips (minkus) overnight to see whether both big-endian
    32-bit architectures behave the same.

    Unfortunately mips has new and exciting failures, and lots of them:

    % grep -c UNEXPECTED-FAIL ../mozjs52.log
    4913

    so is in a considerably worse state than s390x or the powerpc family.

    I've committed changes to pkg-gnome git to make these failures
    non-fatal, and will downgrade the severity of this bug to non-RC when
    those changes have been released.

    The test failures clearly indicate at least one bug, but it isn't clear
    what the severity of that bug is: it could be anything from minor (if
    trivial functionality is broken) to RC (if mozjs52 is basically unusable
    on this architecture).

    Any testing and patches that mips users can provide would be
    appreciated. If the bug(s) isn't/aren't fixed, mozjs52 will either remain available with known test failures if it does basically work, or have its
    old binaries removed from mips (with the test failures becoming a FTBFS)
    if feedback indicates that the test failures are evidence of RC bugs.

    mozjs52 is used by current versions of gjs, so architecture-specific
    removal of mozjs52 would also require architecture-specific removal of gnome-shell, gnome-maps, polari etc., which would in turn make the GNOME
    task and metapackages uninstallable on this architecture.

    Summarizing for those not following #debian-gnome:

    It appears that the mips test failures are actually quite bad (as
    indicated by there being thousands of them rather than just a few),
    and might be causing #878519. Adrian Bunk has been looking into a
    solution.

    My changes in pkg-gnome git are not believed to be sufficient: in
    addition to turning off the JIT, Adrian says we need to fix atomic
    operations to not use jit/none/AtomicOperations-none.h. (It isn't
    at all clear to me why disabling the JIT has any effect on the atomic operations used, but that's how it's written...)
