<pre>From trying to assemble the Linux kernel with Clang, Clang's IA barfs on the
use of a few symbols meant to be relocations:
<instantiation>:7:12: error: immediate must be an integer in range [0, 65535].
movz x30, :abs_g3:-142936536793088
^
<instantiation>:1:1: note: while in macro instantiation
mov_q x30, -142936536793088
^
arch/arm64/kernel/entry.S:282:2: note: while in macro instantiation
tramp_alias x30, tramp_exit_native
^
/tmp/entry-5a0f31.s:1486:2: note: while in macro instantiation
kernel_exit 0
^
Looks like there's errors for :abs_g3:, :abs_g2_nc:, :abs_g1_nc:, and
:abs_g0_nc:.
The author confirmed that this was relocation based, and this SO post seems to
be the most informative on the topic:
