With the kernle fix <http://lists.infradead.org/pipermail/linux-arm-kernel/2015-July/356511.html>, aarch64 GDB is able to read the base of thread area of 32-bit arm program through NT_ARM_TLS. This patch is to teach both GDB and GDBserver to read the base of thread area correctly in the multi-arch case. A new function aarch64_ps_get_thread_area is added, and is shared between GDB and GDBserver. With this patch applied, the following fails in multi-arch testing (GDB is aarch64 but the test cases are arm) are fixed, -FAIL: gdb.threads/tls-nodebug.exp: thread local storage -FAIL: gdb.threads/tls-shared.exp: print thread local storage variable -FAIL: gdb.threads/tls-so_extern.exp: print thread local storage variable -FAIL: gdb.threads/tls-var.exp: print tls_var -FAIL: gdb.threads/tls.exp: first thread local storage -FAIL: gdb.threads/tls.exp: first another thread local storage -FAIL: gdb.threads/tls.exp: p a_thread_local -FAIL: gdb.threads/tls.exp: p file2_thread_local -FAIL: gdb.threads/tls.exp: p a_thread_local second time gdb: 2015-09-18 Yao Qi <yao.qi@linaro.org> * nat/aarch64-linux.c: Include elf/common.h, nat/gdb_ptrace.h, asm/ptrace.h and sys/uio.h. (aarch64_ps_get_thread_area): New function. * nat/aarch64-linux.h: Include gdb_proc_service.h. (aarch64_ps_get_thread_area): Declare. * aarch64-linux-nat.c (ps_get_thread_area): Call aarch64_ps_get_thread_area. gdb/gdbserver: 2015-09-18 Yao Qi <yao.qi@linaro.org> * linux-aarch64-low.c: Don't include sys/uio.h. (ps_get_thread_area): Call aarch64_ps_get_thread_area.
