arm.c (arm_legitimate_index_p): Add VFP load/store index range case.
2010-12-19 Chung-Lin Tang <cltang@codesourcery.com>
gcc/
* config/arm/arm.c (arm_legitimate_index_p): Add VFP load/store
index range case. Change to SF/DFmode tests to avoid capturing HFmode.
(thumb2_legitimate_index_p): Same.
gcc/testsuite/
* gcc.target/arm/vfp-1.c (test_ldst): New test for VFP
load/store immediate indexes.
