[ARM] 4630/1: Fix the vector stride of the double vector instruction. (b9a5ce3c) · Commits · 戴 / test

The vector stride of the double-precision vector instructions must be changed to 1-2 from even 2-4, because the double registers numbering has been changed to 0-15 from even 0-30 by commit. Signed-off-by:
