Split breakpoint_from_pc to breakpoint_kind_from_pc and sw_breakpoint_from_kind
We convert each ARCH_breakpoint_from_pc to ARCH_breakpoint_kind_from_pc and ARCH_sw_breakpoint_from_kind. Note that gdbarch doesn't have methods breakpoint_kind_from_pc and sw_breakpoint_from_kind so far. gdb: 2016-11-03 Yao Qi <yao.qi@linaro.org> * arch-utils.h (GDBARCH_BREAKPOINT_FROM_PC): New macro. (GDBARCH_BREAKPOINT_MANIPULATION_ENDIAN): New macro. * arm-tdep.c (arm_breakpoint_from_pc): Remove. (arm_breakpoint_kind_from_pc): New function. (arm_sw_breakpoint_from_kind): New function. (arm_breakpoint_from_pc): Call arm_breakpoint_kind_from_pc and arm_sw_breakpoint_from_kind. Use GDBARCH_BREAKPOINT_FROM_PC. (arm_remote_breakpoint_from_pc): Call arm_breakpoint_kind_from_pc. (arm_gdbarch_init): Replace set_gdbarch_breakpoint_from_pc with SET_GDBARCH_BREAKPOINT_MANIPULATION. * arc-tdep.c: Likewise. * bfin-tdep.c: Likewise. * cris-tdep.c: Likewise. * iq2000-tdep.c: Likewise. * m32r-tdep.c: Likewise. * mips-tdep.c: Likewise. * mt-tdep.c: Likewise. * nios2-tdep.c: Likewise. * rs6000-tdep.c: Likewise. * score-tdep.c: Likewise. * sh-tdep.c: Likewise. * sh64-tdep.c: Likewise. * tic6x-tdep.c: Likewise. * v850-tdep.c: Likewise. * xtensa-tdep.c: Likewise.
