Hi Maintainers, The attached patch adds gprof support for aarch64. ChangeLog 2013-05-21 Venkataramanan Kumar <Venkataramanan.kumar@linaro.org> * aarch64.c: New file. * corefile.c(find_call): Call aarch64_find_call for bfd_arch_aarch64. * Makefile.am (sources): Add aarch64.c. * Makefile.in: Regenerate. is ok for trunk? regards, Venkat.
