From 289483b6a06c7a24ee9ae9021d2728ca4700b7a6 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Thu, 4 Jan 2018 03:10:34 -0500 Subject: [PATCH] Add new gdb.ada/bp_c_mixed_case testcase for PR gdb/22670 This patch adds a new testcase to demonstrate a regression introduced by: commit b5ec771e60c1a0863e51eb491c85c674097e9e13 Date: Wed Nov 8 14:22:32 2017 +0000 Subject: Introduce lookup_name_info and generalize Ada's FULL/WILD name matching The purpose of the testcase is to verify that a user can insert a breakpoint on a C function while debugging Ada, even if the name of the function includes uppercase letters, requiring us to use Ada's "<...>" notation to tell the GDB that the symbol name should be looked up verbatim. As of the commit above, GDB is no longer finding the function: (gdb) break Function "" not defined. Make breakpoint pending on future shared library load? (y or [n]) Before the patch, the breakpoint was inserted without problem. gdb/testsuite/ChangeLog: PR gdb/22670 * gdb.ada/bp_c_mixed_case: New testcase. Tested on x86_64-linux; generates a KPASS before the regression was introduced, and now generates a KFAIL. --- gdb/testsuite/ChangeLog | 5 +++ gdb/testsuite/gdb.ada/bp_c_mixed_case.exp | 52 ++++++++++++++++++++++ gdb/testsuite/gdb.ada/bp_c_mixed_case/bar.c | 21 +++++++++ .../gdb.ada/bp_c_mixed_case/foo_h731_021.adb | 21 +++++++++ 4 files changed, 99 insertions(+) create mode 100644 gdb/testsuite/gdb.ada/bp_c_mixed_case.exp create mode 100644 gdb/testsuite/gdb.ada/bp_c_mixed_case/bar.c create mode 100644 gdb/testsuite/gdb.ada/bp_c_mixed_case/foo_h731_021.adb diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index a81f9da..c3b38c4 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,6 +1,11 @@ 2018-01-04 Joel Brobecker PR gdb/22670 + * gdb.ada/bp_c_mixed_case: New testcase. + +2018-01-04 Joel Brobecker + + PR gdb/22670 * gdb.ada/complete.exp: Add "complete break ada" test. 2018-01-04 Joel Brobecker diff --git a/gdb/testsuite/gdb.ada/bp_c_mixed_case.exp b/gdb/testsuite/gdb.ada/bp_c_mixed_case.exp new file mode 100644 index 0000000..54c61e3 --- /dev/null +++ b/gdb/testsuite/gdb.ada/bp_c_mixed_case.exp @@ -0,0 +1,52 @@ +# Copyright 2018 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.
