* amd64-tdep.c (amd64_pseudo_register_read_value): Rename from amd64_pseudo_register_read. Change arguments. Call mark_value_bytes_unavailable when needed. (amd64_init_abi): Use set_gdbarch_pseudo_register_read_value, not set_gdbarch_pseudo_register_read. * sentinel-frame.c (sentinel_frame_prev_register): Use regcache_cooked_read_value. * regcache.h (regcache_cooked_read_value): Declare. * regcache.c (regcache_cooked_read_value): New function. (regcache_cooked_read): Call gdbarch_pseudo_register_read_value if available. * i386-tdep.h (i386_pseudo_register_read_value): Declare. (i386_pseudo_register_read): Remove. * i386-tdep.c (i386_pseudo_register_read_into_value): Rename from i386_pseudo_register_read. Change arguments. Call mark_value_bytes_unavailable when needed. (i386_pseudo_register_read_value): New function. (i386_gdbarch_init): Call set_gdbarch_pseudo_register_read_value, not set_gdbarch_pseudo_register_read. * gdbarch.sh (pseudo_register_read_value): New method. * gdbarch.c, gdbarch.h: Rebuild. * findvar.c (value_from_register): Call get_frame_register_value. gdb/testsuite * gdb.dwarf2/typeddwarf.c: XFAIL 'z' on x86-64. * gdb.dwarf2/typeddwarf.exp (xfail-gdb-test): Add arch_pattern argument. * gdb.dwarf2/typeddwarf-amd64.S: New file.
