Created an attachment (id=18651)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18651&action=view)
Proposed fix

The attached patch attempts to solve the issue, by augmenting the range check
in order to match 0 < imm <= size (increasing size in 1).
I checked that the assembler DTRT, so the fix applies to gcc only.

I tested the patch with the gcc test suite plus a test cases I added (included
in the patch).

I forgot the ChangeLog:

gcc/
* config/arm/neon.md (neon_vshll_n): Checking Bounds
fixed.

gcc/testsuite/
* gcc.target/arm/neon/vfp-shift-a2t2.c: New test case.
