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_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.
