From 3dd170be2528487b4c200b531d7abda38d64634f Mon Sep 17 00:00:00 2001 From: Sanimir Agovic Date: Tue, 26 Nov 2013 14:47:16 +0000 Subject: [PATCH] test: cover subranges with present DW_AT_count attribute The dwarf attribute DW_AT_count specifies the elements of a subrange. This test covers subranges with present count but absent upper bound attribute, both with static and dynamic attribute values. testsuite/ChangeLog: * gdb.dwarf2/count.exp: New file. --- gdb/testsuite/ChangeLog | 4 ++ gdb/testsuite/gdb.dwarf2/count.exp | 125 +++++++++++++++++++++++++++++++++++++ 2 files changed, 129 insertions(+) create mode 100644 gdb/testsuite/gdb.dwarf2/count.exp diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 7d0bd2e..2882a74 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,5 +1,9 @@ 2014-04-14 Sanimir Agovic + * gdb.dwarf2/count.exp: New file. + +2014-04-14 Sanimir Agovic + * gdb.base/vla-sideeffect.c: New file. * gdb.base/vla-sideeffect.exp: New file. diff --git a/gdb/testsuite/gdb.dwarf2/count.exp b/gdb/testsuite/gdb.dwarf2/count.exp new file mode 100644 index 0000000..d52fa62 --- /dev/null +++ b/gdb/testsuite/gdb.dwarf2/count.exp @@ -0,0 +1,125 @@ +# Copyright 2014 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.
