From e6ddc3bfedb4665c9d4baa2c85037af25167cdf3 Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Thu, 13 Apr 2017 08:29:43 +0100 Subject: 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 * rl78-tdep.c (rl78_gdbarch_init): Use XCNEW instead of XNEW. * rx-tdep.c (rx_gdbarch_init): Likewise. --- gdb/rl78-tdep.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gdb/rl78-tdep.c') diff --git a/gdb/rl78-tdep.c b/gdb/rl78-tdep.c index 9f2193e..307a760 100644 --- a/gdb/rl78-tdep.c +++ b/gdb/rl78-tdep.c @@ -1412,7 +1412,7 @@ rl78_gdbarch_init (struct gdbarch_info info, struct gdbarch_list *arches) /* None found, create a new architecture from the information provided. */ - tdep = XNEW (struct gdbarch_tdep); + tdep = XCNEW (struct gdbarch_tdep); gdbarch = gdbarch_alloc (&info, tdep); tdep->elf_flags = elf_flags; -- cgit v1.1
