--- Comment #3 from Uroš Bizjak <ubizjak at gmail dot com> ---
At the end of the day, this is target problem.

From _.dfinit dump:

;;  entry block defs     1 [dx] 2 [cx] 6 [bp] 7 [sp] 16 [argp] 20 [frame] 21
[xmm0] 22 [xmm1] 23 [xmm2] 24 [xmm3] 25 [xmm4] 26 [xmm5] 27 [xmm6] 28 [xmm7] 37
[r8] 38 [r9]

Registers DI and SI should also be listed here.

I have a patch.
