Share regcache function regcache_raw_read_unsigned
This patch is in preparation for software single step support on ARM in GDBServer. It adds a new shared function regcache_raw_read_unsigned and regcache_raw_get_unsigned so that GDB and GDBServer can use the same call to fetch a raw register into an integer. No regressions, tested on ubuntu 14.04 ARMv7 and x86. With gdbserver-{native,extended} / { -marm -mthumb } gdb/ChangeLog: * Makefile.in (SFILES): Append common/common-regcache.c. (COMMON_OBS): Append common/common-regcache.o. (common-regcache.o): New rule. * common/common-regcache.h (register_status) New enum. (regcache_raw_read_unsigned): New declaration. * common/common-regcache.c: New file. * regcache.h (enum register_status): Move to common-regcache.h. (regcache_raw_read_unsigned): Likewise. (regcache_raw_get_unsigned): Likewise. gdb/gdbserver/ChangeLog: * Makefile.in (SFILES): Append common/common-regcache.c. (OBS): Append common-regcache.o. (common-regcache.o): New rule. * regcache.c (init_register_cache): Initialize cache to REG_UNAVAILABLE. (regcache_raw_read_unsigned): New function. * regcache.h (REG_UNAVAILABLE, REG_VALID): Replaced by shared register_status enum.
