Add default_breakpoint_from_pc
This patch adds the default implementation of gdbarch breakpoint_from_pc, which is, const gdb_byte * default_breakpoint_from_pc (struct gdbarch *gdbarch, CORE_ADDR *pcptr, int *lenptr) { int kind = gdbarch_breakpoint_kind_from_pc (gdbarch, pcptr); return gdbarch_sw_breakpoint_from_kind (gdbarch, kind, lenptr); } so gdbarch can only defines sw_breakpoint_from_kind and breakpoint_kind_from_pc. gdb: 2016-11-03 Yao Qi <yao.qi@linaro.org> * arch-utils.c (default_breakpoint_from_pc): New function. * arch-utils.h (GDBARCH_BREAKPOINT_FROM_PC): Remove. (GDBARCH_BREAKPOINT_MANIPULATION): Don't use GDBARCH_BREAKPOINT_FROM_PC. (SET_GDBARCH_BREAKPOINT_MANIPULATION): Don't call set_gdbarch_breakpoint_from_pc. (default_breakpoint_from_pc): Remove declaration. * gdbarch.sh (breakpoint_from_pc): Add its default implementation. * gdbarch.c, gdbarch.h: Regenerate. * arm-tdep.c: Don't use GDBARCH_BREAKPOINT_FROM_PC. * arc-tdep.c, bfin-tdep.c, cris-tdep.c, iq2000-tdep.c: Likewise. * m32r-tdep.c, mips-tdep.c, mt-tdep.c: Likewise. * nios2-tdep.c, score-tdep.c, sh-tdep.c: Likewise. * sh64-tdep.c, tic6x-tdep.c, v850-tdep.c, xtensa-tdep.c: Likewise.
