From 9b6da501bff22325867d8afe42fa01d4704e72f8 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 2 Feb 2017 23:36:29 +0000 Subject: Fix "maintenance selftest" printing stray instructions The "maintenance selftest" command is printing odd bits of stray instructions like: ~~~ brkwarning: A handler for the OS ABI "GNU/Linux" is not built into this configuration of GDB.

I.e. "verbose" is only initialized after the base constructor is called. Since the gdb_disassembler_test object is created on the stack, "verbose" has garbage at that point. If the gargage is non-zero, then we end up with the gdb_disassembler_test's stream incorrectly pointing to gdb_stdout. gdb/ChangeLog: 2017-02-02 Pedro Alves * disasm-selftests.c (print_one_insn_test): Move the "verbose" field out of gdb_disassembler_test and make it static. --- gdb/ChangeLog | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 95dfd00..202c90c 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,10 @@ 2017-02-02 Pedro Alves + * disasm-selftests.c (print_one_insn_test): Move the "verbose" + field out of gdb_disassembler_test and make it static. + +2017-02-02 Pedro Alves + * mi/mi-common.h (struct mi_interp): Delete the mi2_interp, mi1_interp and mi_interp fields. -- cgit v1.1
