Dear Maintainer,
I tried to collect some more information and compared this
situation on real hardware armv5tel with an armv7 and
it looks like in keccak_finalize the following instruction
stores different data to memory depending on the arm hardware:
0x005c4ac0 <keccak_finalize+192>: f0 20 c4 e1 strd r2, [r4]
In the failing case this is stored:
(gdb) x/8xb &((keccak_state *) 0xbeffef5c)->a
0xbeffef5c: 0x6f 0x6e 0x20 0x63 0x00 0x00 0x00 0x00
And in the good case this:
(gdb) x/8xb &((keccak_state *) 0xbeffef5c)->a
0xbeffef5c: 0x2e 0x6f 0x6e 0x69 0x6f 0x6e 0x20 0x63
While on both the registers r2 and r3 contain:
r2 0x696e6f2e 1768845102
r3 0x63206e6f 1663069807
In the attached files are some more details leading to the above result.
Kind regards,
Bernhard
