Create tdep->rl78_psw_type lazily
I build GDB for all targets enabled. When I "set architecture rl78", GDB crashes, (gdb) set architecture rl78 Program received signal SIGSEGV, Segmentation fault. append_flags_type_flag (type=0x20cc0e0, bitpos=bitpos@entry=0, name=name@entry=0x11dba3f "CY") at ../../binutils-gdb/gdb/gdbtypes.c:4926 4926 name); (gdb) bt 10 #0 append_flags_type_flag (type=0x20cc0e0, bitpos=bitpos@entry=0, name=name@entry=0x11dba3f "CY") at ../../binutils-gdb/gdb/gdbtypes.c:4926 #1 0x00000000004aaca8 in rl78_gdbarch_init (info=..., arches=<optimized out>) at ../../binutils-gdb/gdb/rl78-tdep.c:1410 #2 0x00000000006b05a4 in gdbarch_find_by_info (info=...) at ../../binutils-gdb/gdb/gdbarch.c:5269 #3 0x000000000060eee4 in gdbarch_update_p (info=...) at ../../binutils-gdb/gdb/arch-utils.c:557 #4 0x000000000060f8a8 in set_architecture (ignore_args=<optimized out>, from_tty=1, c=<optimized out>) at ../../binutils-gdb/gdb/arch-utils.c:531 #5 0x0000000000593d0b in do_set_command (arg=<optimized out>, arg@entry=0x20be851 "rl78", from_tty=from_tty@entry=1, c=c@entry=0x20b1540) at ../../binutils-gdb/gdb/cli/cli-setshow.c:455 #6 0x00000000007665c3 in execute_command (p=<optimized out>, p@entry=0x20be840 "set architecture rl78", from_tty=1) at ../../binutils-gdb/gdb/top.c:666 #7 0x00000000006935f4 in command_handler (command=0x20be840 "set architecture rl78") at ../../binutils-gdb/gdb/event-top.c:577 #8 0x00000000006938d8 in command_line_handler (rl=<optimized out>) at ../../binutils-gdb/gdb/event-top.c:767 #9 0x0000000000692c2c in gdb_rl_callback_handler (rl=0x20be890 "") at ../../binutils-gdb/gdb/event-top.c:200 The cause is that we want to access some builtin types in gdbarch init, but it is not initialized yet. I fix it by creating the type when it is to be used. We've already done this in sparc, sparc64 and m68k. gdb: 2016-12-09 Yao Qi <yao.qi@linaro.org> PR tdep/20953 * rl78-tdep.c (rl78_psw_type): New function. (rl78_register_type): Call rl78_psw_type. (rl78_gdbarch_init): Move code to rl78_psw_type. gdb/testsuite: 2016-12-09 Yao Qi <yao.qi@linaro.org> * gdb.base/all-architectures.exp.in: Remove kfail for rl78.
