When I tried an rpi2 buildworld for clang380-import -r294609 it failed =
with =E2=80=9Crelocation truncated=E2=80=9D problems. (arm7-a cortex-a7 =
no misaligned accesses as my context.)
It looks like this is from picking up base/head=E2=80=99s -r294499 as =
part of forming -r294599 in clang380-import. -r294499 commented out =
having -mlong-calls in /usr/src/lib/clang/clang.lib.mk:
