XCNEW gdbarch_tdep in rl78 and rx
"struct gdbarch_tdep" is XNEW'ed in rl78 and rx, so the memory is not
cleared. As the result, tdep->rl78_psw_type is never initialized
properly.
struct gdbarch_tdep *tdep = gdbarch_tdep (gdbarch);
if (tdep->rl78_psw_type == NULL)
{
tdep->rl78_psw_type = arch_flags_type (gdbarch,
"builtin_type_rl78_psw", 1);
The bug is found by my unit test in the following patch.
gdb:
2017-04-13 Yao Qi <yao.qi@linaro.org>
* rl78-tdep.c (rl78_gdbarch_init): Use XCNEW instead of XNEW.
* rx-tdep.c (rx_gdbarch_init): Likewise.
