New proc is_aarch64_target
Some tests expect the the target is aarch64, but checking target triplet is not accurate, because target triplet can be aarch64 but the program is in arm (or aarch32) state. This patch addes a new proc is_aarch64_target which returns true if the target is on aarch64 state. gdb/testsuite: 2015-07-07 Yao Qi <yao.qi@linaro.org> * gdb.arch/aarch64-atomic-inst.exp: Check is_aarch64_target instead of istarget "aarch64*-*-*". * gdb.arch/aarch64-fp.exp: Likewise. * gdb.base/float.exp: Likewise. * gdb.reverse/aarch64.exp: Likewise. * lib/gdb.exp (is_aarch64_target): New proc.
