Test case
Compiling the C files in reloc.tar.gz for ARM/Linux and linking them into an
executable using gcc (I can't get clang to link for ARM) results in a MOVT
instruction with wrong immediate data.
The C files both contain the string "hello world", and the two copies are
merged by the linker. One of the references to this string is correct,
while the other gets a bad value in the MOVT instruction, which one depends
on the link order.
Compiling to assembler with the -S flag and using the gnu assembler, the
output is correct.
I cannot rule out a bug in the gnu linker, but I am unable to reproduce the
error using only gnu tools.
