Hi Alexei,
The problem is that "0x00800080" can be encoded as an immediate value for
32-bit vector operations, but it cannot be encoded for 64-bit vectors.
(Because the top 32-bits are all zero, and the encoded constant must be a
single pattern). See section C3.3.2 of the ARM ARM.
So 0x0080008000800080 works (single repeating pattern of 0x0080)
But 0x0000000000800080 does not (two patterns)
Cheers
Nick
