GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION
Many archs have only one kind of breakpoint, so their breakpoint_from_pc implementations are quite similar. This patch uses macro GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION for breakpoint_from_pc, so that we can easily switch from breakpoint_from_pc to breakpoint_kind_from_pc and sw_breakpoint_from_kind later. gdb: 2016-11-03 Yao Qi <yao.qi@linaro.org> * arch-utils.h (GDBARCH_BREAKPOINT_MANIPULATION): New macro. (SET_GDBARCH_BREAKPOINT_MANIPULATION): New macro. aarch64-tdep.c (aarch64_breakpoint_from_pc): Remove. Use GDBARCH_BREAKPOINT_MANIPULATION. (aarch64_gdbarch_init): Replace set_gdbarch_breakpoint_from_pc with SET_GDBARCH_BREAKPOINT_MANIPULATION. * alpha-tdep.c: Likewise. * avr-tdep.c: Likewise. * frv-tdep.c: Likewise. * ft32-tdep.c: Likewise. * h8300-tdep.c: Likewise. * hppa-tdep.c: Likewise. * i386-tdep.c: Likewise. * lm32-tdep.c: Likewise. * m32c-tdep.c: Likewise. * m68hc11-tdep.c: Likewise. * m68k-tdep.c: Likewise. * m88k-tdep.c: Likewise. * mep-tdep.c: Likewise. * microblaze-tdep.c: Likewise. * mn10300-tdep.c: Likewise. * moxie-tdep.c: Likewise. * msp430-tdep.c: Likewise. * rl78-tdep.c: Likewise. * rx-tdep.c: Likewise. * s390-linux-tdep.c: Likewise. * sparc-tdep.c: Likewise. * spu-tdep.c: Likewise. * tilegx-tdep.c: Likewise. * vax-tdep.c: Likewise. * xstormy16-tdep.c: Likewise.
