From: Maciej W. Rozycki Date: Wed, 19 Jan 2022 21:55:10 +0000 (+0000) Subject: Add `set print repeats' tests for C/C++ arrays X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6b4338c868e96a549af44fdf17141f4eac77e225;p=binutils-gdb.git Add `set print repeats' tests for C/C++ arrays Add `set print repeats' tests for C/C++ arrays, complementing one for Fortran arrays and covering the different interpretation of the `set print elements' setting in particular where the per-dimension count of the elements handled is matched against the trigger rather than the total element count as with Fortran arrays. --- diff --git a/gdb/testsuite/gdb.base/array-repeat.c b/gdb/testsuite/gdb.base/array-repeat.c new file mode 100644 index 00000000000..6682b8c3e30 --- /dev/null +++ b/gdb/testsuite/gdb.base/array-repeat.c @@ -0,0 +1,63 @@ +/* Copyright 2022 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.
