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
