btrace: extend struct btrace_insn
Add the instruction's size as well as a coarse classification to struct
btrace_insn. Use the information in ftrace_update_function and
ftrace_find_call.
2015-02-09 Markus Metzger <markus.t.metzger@intel.com>
* btrace.h (btrace_insn_class): New.
(btrace_insn) <size, iclass>: New.
* btrace.c (ftrace_find_call): Update parameters. Update users.
Use instruction classification.
(ftrace_new_return): Update parameters. Update users.
(ftrace_update_function): Update parameters. Update users. Use
instruction classification.
(ftrace_update_insns): Update parameters. Update users.
(ftrace_classify_insn): New.
(btrace_compute_ftrace_bts): Fill in new btrace_insn fields. Add
TRY_CATCH around call to gdb_insn_length.
