PR tdep/9390: Fix typo on xstorxstormy16-tdep.c
This patch fixes the bug described in PR tdep/9390, which is about a
wrong check in the following code:
...
/* optional copying of args in r2-r7 to r10-r13. */
/* Probably only in optimized case but legal action for prologue. */
else if ((inst & 0xff00) == 0x4600 /* 46SD mov rD, rS */
&& (inst & 0x00f0) >= 0x0020 && (inst & 0x00f0) <= 0x0070
&& (inst & 0x000f) >= 0x00a0 && (inst & 0x000f) <= 0x000d)
^^^^^^^^^^^^^^^^^^^^^^^^^
...
This condition will never trigger, and the fix proposed in the bug
(which made sense to me) was to test against 0x000a. I tried finding
documentation about this target, but couldn't find anything. I don't
even know if it is still used, but decided to submit the fix anyway.
Tested on my x86_64 Fedora 20 GNU/Linux.
