gdbarch: add instruction predicate methods
Add new methods to gdbarch for analyzing the instruction at a given address. Implement those methods for i386 and amd64 architectures. This is needed by "record btrace" to detect function calls in the execution trace. 2014-01-16 Markus Metzger <markus.t.metzger@intel.com> * amd64-tdep.c (amd64_classify_insn_at, amd64_insn_is_call) (amd64_insn_is_ret, amd64_insn_is_jump, amd64_jmp_p): New. (amd64_init_abi): Add insn_is_call, insn_is_ret, and insn_is_jump to gdbarch. * i386-tdep.c (i386_insn_is_call, i386_insn_is_ret) (i386_insn_is_jump, i386_jmp_p): New. (i386_gdbarch_init): Add insn_is_call, insn_is_ret, and insn_is_jump to gdbarch. * gdbarch.sh (insn_is_call, insn_is_ret, insn_is_jump): New. * gdbarch.h: Regenerated. * gdbarch.c: Regenerated. * arch-utils.h (default_insn_is_call, default_insn_is_ret) (default_insn_is_jump): New. * arch-utils.c (default_insn_is_call, default_insn_is_ret) (default_insn_is_jump): New.
