            Bug ID: 103673
           Summary: avr-gcc with -mrelax with .balign is buggy
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: therealdragony at gmx dot de
  Target Milestone: ---

Compile the following assembler code with avr-gcc

.rept 300
call test
.endr

ldi ZL,lo8(matrix)
ldi ZH,hi8(matrix)

1:rjmp 1b

test:
ret

.balign 256
matrix:
.byte 1,2,3,4,5


Then look at .lss

 250:   06 d0           rcall   .+12            ; 0x25e <test>
 252:   05 d0           rcall   .+10            ; 0x25e <test>
 254:   04 d0           rcall   .+8             ; 0x25e <test>
 256:   03 d0           rcall   .+6             ; 0x25e <test>
 258:   e8 ea           ldi     r30, 0xA8       ; 168
 25a:   f2 e0           ldi     r31, 0x02       ; 2
 25c:   ff cf           rjmp    .-2             ; 0x25c <const_1s_max+0x1dd>

0000025e <test>:
 25e:   08 95           ret
        ...

00000300 <matrix>:
 300:   01 02           muls    r16, r17
 302:   03 04           cpc     r0, r3
 304:   05 00           .word   0x0005  ; ????

As you can see, the ldi is loading 0x02AB, which is wrong, as the matrix is
(correctly) located at 0x0300.

Compiled via:

#avr-gcc --version
avr-gcc (GCC) 10.2.0

#avr-gcc main.S -o main.elf -Wall -Wextra -std=gnu99 -mmcu=atxmega384c3 
-nostartfiles -mrelax -Wl,--no-stubs -Wa,--no-pad-sections

#avr-objdump -DSg main.elf > main.lss

PS: This is my first bug report at all. I'm sorry if it contains formal
mistakes.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You should report this to binutils (https://sourceware.org/bugzilla) as this is
the assembler you are complaining about and gcc does not contain the assembler.
