[Bug ld/5552] New: Wrong data address after linking

Subject: [Bug ld/5552] New: Wrong data address after linking
Date: 8 Jan 2008 13:16:04 -0000

While porting Linux to the Fujitsu RISC I observed that pointers within
a structure were not initialized with the right addresses.
After some investigation it boiled down to the linker.

Following testcase shows the problem.

foo.s:
        .globl foo
        .data
        .p2align 2
        .type   foo, @object
        .size   foo, 8
foo:
        .word   286331153
        .word   foo+4
        .word   foo+4
        .word   -1
        
        .globl bar
        .data
        .p2align 2
        .type   bar, @object
        .size   bar, 40
bar:
        .word   286331153
        .word   bar+4
        .word   bar+4
        .word   -1
        
assembled with:
bash-2.05b$ fr30-elf-as foo.s -o foo.o

and linked with:
bash-2.05b$ fr30-elf-ld -t -stats foo.o
fr30-elf-ld: mode elf32fr30
foo.o
fr30-elf-ld: warning: cannot find entry symbol _start; defaulting to 00010000


What I would expect is: a2.out
00001000: 11111111      foo
00001004: 00010004
00001008: 00010004
0000100c: ffffffff
00001010: 11111111      bar
00001014: 00010014      <
00001018: 00010014      <
0000101c: ffffffff

But what I get is: a.out
00001000: 11111111      foo
00001004: 00010004
00001008: 00010004
0000100c: ffffffff
00001010: 11111111      bar
00001014: 00010024      <
00001018: 00010024      <
0000101c: ffffffff
