[GDBserver] Centralize tdesc for i386-linux
tdesc_i386_XXX_linux is used in many places in linux-x86-low.c and this
patch adds a new function i386_linux_read_description to return the right
tdesc according to xcr0. i386_linux_read_description is quite similar to
the counterpart in GDB, and the following patch will share the duplicated
code, so this patch adds arch/tdesc.h includes the declarations of various
tdesc apis which are used by the shared code. The generated c feature
files can include arch/tdesc.h only.
gdb/gdbserver:
2017-09-05 Yao Qi <yao.qi@linaro.org>
* configure.srv (srv_tgtobj): Append linux-x86-tdesc.o.
(ipa_obj): Likewise.
* linux-i386-ipa.c: Include common/x86-xstate.h
(get_ipa_tdesc): Call i386_linux_read_description.
(initialize_low_tracepoint): Don't call init_registers_XXX
functions, call initialize_low_tdesc instead.
* linux-x86-low.c (x86_linux_read_description): Call
i386_linux_read_description.
(initialize_low_arch): Don't call init_registers_i386_XXX
functions, call initialize_low_tdesc.
* linux-x86-tdesc.c: New file.
* linux-x86-tdesc.h (x86_linux_tdesc): New X86_TDESC_LAST.
(i386_get_ipa_tdesc_idx): Declare.
(i386_get_ipa_tdesc): Declare.
(initialize_low_tdesc): Declare.
gdb:

declarations.
