Add a structure to hold the branch trace data and an enum to describe the format of that data. So far, only BTS is supported. Also added a NONE format to indicate that no branch trace data is available. This will make it easier to support different branch trace formats in the future. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * Makefile.in (SFILES): Add common/btrace-common.c. (COMMON_OBS): Add common/btrace-common.o. (btrace-common.o): Add build rules. * btrace.c (parse_xml_btrace): Update parameters. (parse_xml_btrace_block): Set format field. (btrace_add_pc, btrace_fetch): Use struct btrace_data. (do_btrace_data_cleanup, make_cleanup_btrace_data): New. (btrace_compute_ftrace): Split into this and... (btrace_compute_ftrace_bts): ...this.
