; Two things to check here: the @earlyclobber constraint (on <= v5) and the "$Rd = $R" ones.
; + Without @earlyclobber the v7 code is natural. With it, the first two
; registers must be distinct from the third.
; + Without "$Rd = $R", this can be satisfied without a mov before the umlal
; by trying to use 6 different registers in the MachineInstr. The natural
; evolution of this attempt currently leaves only two movs in the final
; function, both after the umlal. With it, *some* move has to happen
; before the umlal.

[ARM] Predicate UMAAL selection on hasDSP. UMAAL is a DSP instruction and it is not available on thumbv7m (Cortex-M3) and thumbv6m (Cortex-M0+1) targets. Also fix wrong CHECK prefix in longMAC.ll test. Patch by Vadzim Dambrouski. Differential Revision: https://reviews.llvm.org/D25890 llvm-svn: 285278
