Workaround in the same way. Changed definition of the INNER_LOOP_ITERATION
(https://github.com/weidai11/cryptopp/blob/master/vmac.cpp#L549):
#define INNER_LOOP_ITERATION(j) {\
word64 d0 = ConditionalByteReverse(LITTLE_ENDIAN_ORDER, data[i+2*j+0]);\
word64 d1 = ConditionalByteReverse(LITTLE_ENDIAN_ORDER, data[i+2*j+1]);\
AccumulateNH(nhA, d0+nhK[i+2*j+0], d1+nhK[i+2*j+1]);\
if (T_128BitTag)\
AccumulateNH(nhB, d0+nhK[i+2*j+2], d1+nhK[i+2*j+3]);\
}
To:
#if defined(__SUNPRO_CC)
#define PREPARE_D0_D1(j) \
word64 d0_original = 0;\
memcpy(&d0_original, data + i + 2*j + 0,
sizeof(d0_original));\
word64 d1_original = 0;\
memcpy(&d1_original, data + i + 2*j + 1,
sizeof(d1_original));\
\
word64 d0 = ConditionalByteReverse(LITTLE_ENDIAN_ORDER,
d0_original);\
word64 d1 = ConditionalByteReverse(LITTLE_ENDIAN_ORDER,
d1_original)
#else
#define PREPARE_D0_D1(j) \
word64 d0 = ConditionalByteReverse(LITTLE_ENDIAN_ORDER,
data[i+2*j+0]);\
word64 d1 = ConditionalByteReverse(LITTLE_ENDIAN_ORDER,
data[i+2*j+1])
#endif
#define INNER_LOOP_ITERATION(j) {\
PREPARE_D0_D1(j);\
AccumulateNH(nhA, d0+nhK[i+2*j+0], d1+nhK[i+2*j+1]);\
if (T_128BitTag)\
AccumulateNH(nhB, d0+nhK[i+2*j+2],
d1+nhK[i+2*j+3]);\
}
