--- Comment #11 from Nico Weber <nicolasweber at gmx.de> ---
This isn't fixed for boringssl in a chromium bug (which is probably the same
source that the openssl bit is reduced from). Maybe it's due to thumb:

thakis at thakis:~/src/chrome/src/out/gnand$ cat
../../third_party/boringssl/linux-arm/crypto/aes/bsaes-armv7.S 
.arch    armv7-a
.fpu    neon

.text
.syntax    unified     @ ARMv7-capable assembler is expected to handle this
.thumb

.type    _bsaes_decrypt8,%function
.align    4
_bsaes_decrypt8:
    adr    r6,_bsaes_decrypt8
    vldmia    r4!, {q9}        @ round 0 key
    add    r6,r6,#.LM0ISR-_bsaes_decrypt8

.type    _bsaes_const,%object
.align    6
_bsaes_const:
.LM0ISR:@ InvShiftRows constants
.quad    0x0a0e0206070b0f03, 0x0004080c0d010509
