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.

[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.

Dynamically composite xml in reply to GDB GDBserver still uses pre-generated target descriptions in order to reply to GDB's query on target description (see xml-builtin-generated.c in GDBserver build directory). This patch teaches GDBserver to create XML contents according to the target descriptions rather than using pre-generated ones. First, change target feature c files to pass the feature xml file name to tdesc_create_feature, so that target description in GDBserver can record them, and create XML contents from these features in buffer, like ... <xi:include href="$FEATURE1_XML_NAME"/> <xi:include href="$FEATURE2_XML_NAME"/> ... and send this buffer back to GDB. Note that this patch reuses target_desc.xmltarget a little bit, which is to hold the XML contents dynamically generated in tdesc_get_features_xml. However, it is not xfree'ed in ~target_desc, because we can't tell it is from xstrdup or a literal string. Since we don't delete target_desc, there is no memory leak yet. After we change all target descriptions to the new style, target_desc.xmltarget is from xstrdup, then, we can safely xfree it in ~target_desc. gdb: 2017-09-05 Yao Qi <yao.qi@linaro.org> * arch/tdesc.h (tdesc_create_feature): Add an argument xml. * target-descriptions.c (tdesc_create_feature): Likewise, and adjust code. * features/i386/32bit-avx.c: Re-generated. * features/i386/32bit-avx512.c: Re-generated. * features/i386/32bit-core.c: Re-generated. * features/i386/32bit-linux.c: Re-generated. * features/i386/32bit-mpx.c: Re-generated. * features/i386/32bit-pkeys.c: Re-generated. * features/i386/32bit-sse.c: Re-generated. gdb/gdbserver: 2017-09-05 Yao Qi <yao.qi@linaro.org> * linux-x86-tdesc.c: Don't include <inttypes.h>.
