GDB tests running on arm target should be also run on aarch32 (32-bit mode on aarch64). There should be no difference. It is not precise to check target triplet to decide which tests should be run, because if I compiler all the test binary in 32-bit (arm program), but target triplet is still aarch64, so that these arm specific tests are skipped. This patch is to add a new proc is_aarch32_target which return true if target triplet is arm or the test binary is compiled for arm. gdb/testsuite: 2015-07-07 Yao Qi <yao.qi@linaro.org> * lib/gdb.exp (is_aarch32_target): New proc. * gdb.arch/arm-bl-branch-dest.exp: Check is_aarch32_target instead of "istarget "arm*-*-*"". * gdb.arch/arm-disp-step.exp: Likewise. * gdb.arch/thumb-bx-pc.exp: Likewise. * gdb.arch/thumb-prologue.exp: Likewise. * gdb.arch/thumb-singlestep.exp: Likewise. * gdb.base/disp-step-syscall.exp: Likewise. * gdb.base/float.exp: Likewise.
