[binutils-gdb] Change tic6x target descriptions


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=506fe5f4996738f25b7c26f126a84b231429ba95

commit 506fe5f4996738f25b7c26f126a84b231429ba95
Author: Yao Qi <yao.qi@linaro.org>
Date:   Fri Nov 24 09:29:43 2017 +0000

    Change tic6x target descriptions
    
    This patch changes tic6x target descriptions to be more flexible.  Rebuild
    tic6x-uclinux GDBserver with my x86 g++, and the unit test passes.
    
    gdb:
    
    2017-11-24  Yao Qi  <yao.qi@linaro.org>
    
    	* arch/tic6x.c: New file.
    	* arch/tic6x.h: New file.
    	* features/Makefile (FEATURE_XMLFILES): Add tic6x-c6xp.xml,
    	tic6x-core.xml and tic6x-gp.xml.
    	* features/tic6x-c6xp.c: Generated.
    	* features/tic6x-core.c: Generated.
    	* features/tic6x-gp.c: Generated.
    	* target-descriptions.c (maint_print_c_tdesc_cmd): Match
    	"tic6x-".
    
    gdb/gdbserver:
    
    2017-11-24  Yao Qi  <yao.qi@linaro.org>
    
    	* configure.srv: Set $srv_regobj for tic6x-linux.
    	* linux-tic6x-low.c: Include "arch/tic6x.h" and "tdesc.h".
    	(tic6x_read_description): Move some code to tic6x_arch_setup.
    	(tic6x_tdesc_test): New function.
    	(initialize_low_arch): Call selftests::register_test.
