The main user, u-boot, added the workaround with -fno-ira-hoist-pressure=20
to avoid the bug:

    arch/powerpc/config.mk: Pass -fno-ira-hoist-pressure when possible

    There are various toolchain issues that cause us to produce invalid
    binaries with certain gcc 4.8.x and 4.9.x versions when we don't pass
    this flag in.

    Tested-by: Joakim Tjernlund <joakim.tjernlund@transmode.se>
    Signed-off-by: Tom Rini <trini@konsulko.com>

The bug is still there as far as I known, the one-line patch hasn't been
applied
I think.=
