Some btrace tests use assembly source files. They use the target triplet to distinguish between x86_64 and ia32 ISA. This does not work for -m32 tests without setting the target triplet to i686-?-?. Instead use is_amd64_regs_target to distinguish between x86_64 and ia32 ISA. See also https://sourceware.org/ml/gdb-patches/2016-07/msg00256.html. testsuite/ * gdb.btrace/record_goto.exp: Use is_amd64_regs_target for selecting assembly source files. * gdb.btrace/stepi.exp: Use is_amd64_regs_target for selecting assembly source files. * gdb.btrace/tailcall.exp: Use is_amd64_regs_target for selecting assembly source files. * gdb.btrace/tailcall-only.exp: Use is_amd64_regs_target for selecting assembly source files.
