Generate c for feature instead of tdesc
This patch changes Makefile and command "maint print c-files" so that GDB can print c files for features instead target description. Previously, we feed GDB a target description xml file, which generate c files including multiple features. With this patch, in Makefile, we wrap each feature xml file, and create a temp target description which include only one feature. Then, adjust the target description printer for them, and print a c function for each given feature, so that we can use these c functions later to create target description in a flexible way. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * features/Makefile (CFILES): Rename with TDESC_CFILES. (FEATURE_XMLFILES): New. (FEATURE_CFILES): New. New rules. (clean-cfiles): Remove generated c files. * features/i386/32bit-avx.c: Generated. * features/i386/32bit-avx512.c: Generated. * features/i386/32bit-core.c: Generated. * features/i386/32bit-linux.c: Generated. * features/i386/32bit-mpx.c: Generated. * features/i386/32bit-pkeys.c: Generated. * features/i386/32bit-sse.c: Generated. * target-descriptions.c: Include algorithm. (tdesc_element_visitor): Add method visit_end. (print_c_tdesc): Implement visit_end. (print_c_tdesc:: m_filename_after_features): Move it to protected. (print_c_feature): New class. (maint_print_c_tdesc_cmd): Use print_c_feature if XML file name starts with "i386/32bit-".
