[PATCH, ARM] Validate that target really supports LDRD/STRD before use

2013-09-18 Thread Richard Earnshaw
On ARM targets that normally support LDRD/STRD there are tuning parameters that express the preference for using these instructions over LDM/STM. However, that's only a preference and when the architecture and tuning options differ (for example, tuning for Cortex-A15 but using the ARMv5 ISA) then
