--- Comment #1 from Richard Earnshaw <rearnsha at sourceware dot org> ---
Labels are just constants that get assigned by the assembler. But the bigger
problem here is that we silently convert an absolute value into something PC
relative and that's clearly incorrect:
If I run your testcase through "objdump -dr", I see:
0000000000000000 <.text>:
0: 36080020 tbz w0, #1, 4 <.text+0x4>
4: 37080020 tbnz w0, #1, 8 <.text+0x8>
8: 90000000 adrp x0, 0 <.text>
8: R_AARCH64_ADR_PREL_PG_HI21 *ABS*+0x4
So the first two instructions have clearly been assembled incorrectly, but the
third is (technically) correct in that has a pc-relative relocation relative to
the absolute section (whether or not that's what the user really intended is
somewhat tangential).
