        <pre>Building arch/arm/kernel/sleep.S in linux kernel for ARM with integrated
assembler ended up with the following assertion failure:

arch/arm/kernel/sleep.S:149:20: error: invalid reassignment of non-absolute
variable 'up_b_offset' in '.equ' directive
.equ up_b_offset, 1f - 9998b ; .pushsection ".alt.smp.init", "a" ; .long 9998b
; b . + up_b_offset ; .popsection


I was able to reduce the code to as follows, using X86 assembly,


$ cat repro.s
0:
.equ x, 1f - 0b ;
jmp . + x ;
1:


$ llvm-mc -triple i386 repro.s -filetype=obj -o /dev/null

repro.s:5:9: error: invalid reassignment of non-absolute variable 'x' in '.equ'
directive
.equ x, 0xff ;

$ gcc -c repro.s
$ echo $?
