From a9680e0e54cfd8a12ddb1a583b4acb96dc2bbdbd Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Mon, 23 Aug 2021 12:08:25 +0200 Subject: [PATCH] [gdb] Fix 'not in executable format' error message With trying to load a non-executable file into gdb, we run into PR26880: ... $ gdb -q -batch test.c "0x7ffc87bfc8d0s": not in executable format: \ file format not recognized ... The problem is caused by using %ps in combination with the error function (note that confusingly, it does work in combination with the warning function). Fix this by using plain "%s" instead. Tested on x86_64-linux. gdb/ChangeLog: 2021-08-22 Tom de Vries PR gdb/26880 * gdb/exec.c (exec_file_attach): Use %s instead of %ps in call to error function. gdb/testsuite/ChangeLog: 2021-08-22 Tom de Vries PR gdb/26880 * gdb.base/non-executable.exp: New file. --- gdb/exec.c | 8 +++--- gdb/testsuite/gdb.base/non-executable.exp | 32 +++++++++++++++++++++++ 2 files changed, 35 insertions(+), 5 deletions(-) create mode 100644 gdb/testsuite/gdb.base/non-executable.exp diff --git a/gdb/exec.c b/gdb/exec.c index 6f936c9403f..1be51474b4a 100644 --- a/gdb/exec.c +++ b/gdb/exec.c @@ -453,9 +453,8 @@ exec_file_attach (const char *filename, int from_tty) if (!current_program_space->exec_bfd ()) { - error (_("\"%ps\": could not open as an executable file: %s."), - styled_string (file_name_style.style (), scratch_pathname), - bfd_errmsg (bfd_get_error ())); + error (_("\"%s\": could not open as an executable file: %s."), + scratch_pathname, bfd_errmsg (bfd_get_error ())); } /* gdb_realpath_keepfile resolves symlinks on the local @@ -475,8 +474,7 @@ exec_file_attach (const char *filename, int from_tty) /* Make sure to close exec_bfd, or else "run" might try to use it. */ current_program_space->exec_close (); - error (_("\"%ps\": not in executable format: %s"), - styled_string (file_name_style.style (), scratch_pathname), + error (_("\"%s\": not in executable format: %s"), scratch_pathname, gdb_bfd_errmsg (bfd_get_error (), matching).c_str ()); } diff --git a/gdb/testsuite/gdb.base/non-executable.exp b/gdb/testsuite/gdb.base/non-executable.exp new file mode 100644 index 00000000000..4ae123a2cb2 --- /dev/null +++ b/gdb/testsuite/gdb.base/non-executable.exp @@ -0,0 +1,32 @@ +# Copyright 2021 Free Software Foundation, Inc. + +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
