Running gas twice over the same input results in different object files if ASLR
is enabled. This has been first reported here
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=123743
For example, running gas twice over the attached example on s390x results in:
$ as --gdwarf-5 -m64 -mzarch -march=z196 affinity.s -o t1.o
$ as --gdwarf-5 -m64 -mzarch -march=z196 affinity.s -o t2.o
$ cmp --ignore-initial=16 t1.o t2.o
t1.o t2.o differ: byte 7541, line 18
One time we have:
Disassembly of section .rodata.cst8:
0000000000000000 <.LC17>:
0: 00 00 00 00 .long 0x00000000
4: 02 60 2a 58 .long 0x02602a58
and for the other object file we have:
Disassembly of section .rodata.cst8:
0000000000000000 <.LC17>:
0: 00 00 00 00 .long 0x00000000
4: 01 4d 3a 58 .long 0x014d3a5
